Finca Nature & Coexistence Statement

Finca Astronómica

Foundational information, operating principles and rules

This statement records the environmental, operational and coexistence principles behind Finca Astronómica. It is intended as a source of truth for public information, client communication, policies, FAQs and operational guidance. Finca Astronómica is an astronomical and science-education facility operating in a real rural, off-grid environment. Its astronomy, animals, land, water, energy systems and guest activities are therefore managed as parts of one interconnected system.

Why do we have animals?

1. Astronomy doesn't stop at the telescope

Astronomy is the study of the Universe - and Earth is part of that Universe.

Understanding our own planet, its atmosphere, climate, geology, ecosystems and life is

fundamental to understanding what makes planets habitable. Some of the biggest questions in

modern astronomy concern the conditions necessary for life and whether those conditions exist

elsewhere.

We look outward to understand other worlds, but Earth is the only living

world we currently know.

For us, astronomy education therefore doesn't finish when somebody steps away from a

telescope. Understanding the natural world around us is part of understanding our place in the

Universe.

2. Astronomy has an unusually close relationship with nature

Astronomical observatories need darkness, open skies and distance from major sources of

artificial light. For that reason, they are frequently located in remote rural areas, mountains,

deserts and other places where natural environments remain relatively undisturbed.

That creates both an opportunity and a responsibility.

The natural environment surrounding an observatory isn't simply empty space around the

astronomy facility. It is often one of the reasons astronomy is possible there in the first place.

Responsible astronomical activity therefore means thinking not only about protecting the night

sky from light pollution, but also about our impact on the land beneath it: wildlife, vegetation,

water, soil, waste, noise, traffic and the wider ecosystem.

We don't believe that protecting the night sky while damaging everything

underneath it makes much sense.

3. Finca Astronómica is designed around coexistence

Finca Astronómica exists within a real rural landscape. We are situated in an agricultural area,

close to the transition between land with limited agricultural possibilities and the natural

mountain environment.

We don't want to remove nature from the property in order to create a sanitised astronomical

attraction.

Our approach is the opposite: how can an astronomical and educational facility operate while

remaining part of the landscape that makes its work possible?

That means finding practical ways for people, astronomy, agriculture, animals and the natural

environment to coexist.

The Finca itself therefore becomes part of what we teach. It is an opportunity to demonstrate that

scientific activity and environmental responsibility don't have to compete with one another.

4. Our animals have practical roles

The animals at Finca Astronómica are not simply decoration. They form part of how we manage

the property and its resources.

Depending on the species, they contribute to:

vegetation and land management;
responsible use of suitable organic food and plant material;
natural nutrient cycles through manure and composting;
insect and pest management;
food production, including eggs;
reducing unnecessary waste;
reducing reliance on intensive mechanical or chemical land-management methods;
maintaining a functioning rural environment;
teaching children and adults about ecosystems, biodiversity, sustainability and responsible animal care.

This is particularly relevant in a Mediterranean environment, where responsible vegetation

management is also important for maintaining the land and controlling excessive dry vegetation.

The animals therefore connect the scientific, educational and practical sides of Finca

Astronómica: from understanding life on our own planet to demonstrating how humans can

operate within a rural ecosystem rather than simply replacing it.

We don't just protect the sky above Finca Astronómica. We protect and work

with the environment underneath it.

Animals & Hygiene

Hygiene in a living rural environment

Finca Astronómica is an open-air rural venue. The presence of animals and wildlife is therefore

considered as part of the hygiene system rather than something whose existence can simply be

excluded from it.

A rural environment is not a sterile environment.

Soil contains microorganisms. Plants attract insects. Birds cross the property. Domestic animals

live here. Wind carries pollen, dust, leaves and feathers.

Hygiene does not mean eliminating nature. It means identifying and controlling meaningful

routes of contamination and disease.

The objective is therefore neither to create a sterile environment nor to operate an uncontrolled

farmyard. It is to maintain a properly managed rural environment in which animals, visitors,

food service and educational activities can coexist safely.

Separation of activities and controlled areas

Animal care and food handling are separate activities.

Food preparation, food storage and the bar are controlled areas. Food, ingredients, utensils,

crockery and food-service equipment are kept separate from animal-care equipment, animal feed

and animal housing.

Animal feeding containers, cleaning equipment and other animal-care materials are not used for

preparing or serving human food.

Anyone moving from animal-care activities to food handling must follow appropriate hand

hygiene before doing so.

The fact that animals live on the wider property does not mean that animals are permitted to

contaminate food or food-contact surfaces.

The dining environment

Finca Astronómica has a large open-air dining and activity area with tables and seating.

This is deliberately an outdoor space rather than an enclosed restaurant environment. It remains

physically connected with the landscape and forms part of the experience of being at the Finca.

As an outdoor environment, it is potentially accessible to domestic animals, wild birds, insects

and other wildlife.

The dining area is cleaned and maintained regularly and prepared for activities, but it is not

intended or represented as a sterile indoor environment.

The terrace and buffet area

The bar opens directly onto a large covered terrace with a hard concrete floor. During activities,

this terrace becomes the principal food-service and buffet area.

Buffet tables are prepared there and dishes are brought out for service.

Food is not permanently stored on the terrace. Preparation and storage take place separately, and

food is brought into the service area when required.

The hard flooring allows the area to be inspected, swept, washed and cleaned considerably more

effectively than untreated agricultural ground. The terrace remains, however, an outdoor space.

Animals can access outdoor areas

Some animals at Finca Astronómica are free-ranging within appropriate parts of the property.

Wild birds and other wildlife naturally cannot be excluded from an open rural environment.

Animals may therefore cross the dining or terrace areas when they are not occupied. Birds may

occasionally leave feathers or droppings. Wind may introduce leaves, dust or other natural

material. An area that has been cleaned can subsequently be crossed by a bird or animal.

These are normal realities of maintaining an outdoor environment in which nature has not been

physically excluded. They do not remove the requirement for cleaning.

Outdoor guest and food-service areas are inspected and cleaned regularly and as appropriate

before and during their use. Visible animal waste in areas being used by guests is removed and

affected surfaces are cleaned.

During activities, and particularly when large numbers of people occupy the dining and buffet

areas, birds and other animals generally avoid the activity naturally.

Clean does not mean sterile

The possibility that a feather, insect or bird dropping may occasionally appear somewhere within

a large outdoor area does not in itself demonstrate inadequate hygiene.

Equally, describing something as natural does not mean that it should simply remain in a guest

area.

The relevant question is whether contamination is appropriately identified, removed and

prevented from reaching food and food-contact surfaces.

An outdoor rural environment can be clean without being sterile.

Cleaning an outdoor terrace also cannot permanently seal it from the environment. A bird may

cross it afterwards. Wind may carry something onto it afterwards. An insect may land there

afterwards.

The appropriate response to new contamination is further cleaning where required, rather than

attempting to create an impossible guarantee that nature cannot subsequently enter an outdoor

space.

Food-contact surfaces are different from the surrounding environment

A fundamental distinction exists between environmental surfaces and food-contact surfaces.

The concrete terrace floor, surrounding ground, gravel, gardens and other outdoor surfaces are

not food-contact surfaces.

Food, plates, serving utensils, containers, preparation surfaces and equipment that directly

contacts food require a different level of hygiene control.

Hygiene measures therefore concentrate particularly on realistic contamination pathways:

food preparation and storage;
food-contact surfaces;
serving equipment and utensils;
crockery;
hand hygiene;
appropriate food handling;
prevention of direct animal contact with food;
cleaning or replacement of anything that becomes contaminated.

Attempting to make every square metre of an outdoor finca microbiologically equivalent to a

kitchen worktop would be neither possible nor hygienically meaningful.

Food and animals

Animals are not permitted to feed from buffet dishes or interfere with food intended for guests.

If food itself is contaminated through animal contact or another significant source of

contamination, it is removed from service.

If a food-contact surface, utensil or serving item becomes contaminated, it must be appropriately

cleaned or replaced before further use.

The presence of animals within the wider environment is therefore fundamentally different from

accepting animal contact with human food.

Hand hygiene

Direct transfer from hands to the mouth or food is an important potential contamination

pathway following animal contact.

Hands should therefore be washed after direct contact with animals, animal waste, animal

housing or animal-care equipment and before preparing, serving or consuming food.

Guests, particularly children, who interact with animals should likewise wash their hands before

eating.

People undertaking animal-care tasks should not move directly into food-handling tasks without

appropriate hand hygiene and separation of activities.

Animal-area hygiene and welfare

Animal housing, feeding and drinking areas have their own cleaning and maintenance

requirements.

Manure and other animal waste are managed rather than being allowed to accumulate

indiscriminately. Feeding equipment, drinking water, bedding and living areas are maintained

according to the requirements of the relevant species.

This is not simply a matter of maintaining an appropriate environment for visitors. Proper

hygiene is fundamental to animal health and welfare as well.

The principle

Finca Astronómica does not teach sustainability, ecosystems and biodiversity as abstract concepts

while attempting to remove every manifestation of the natural world from the property.

Animals live here. Wildlife passes through. Plants grow here. People visit, eat, learn and observe

the Universe here.

These activities have different requirements, and those requirements are managed accordingly.

The objective is neither 'nature must never be visible' nor 'anything goes because this is the

countryside.' It is responsible coexistence supported by practical management.

Coexistence requires management, not sterilisation.

Dogs & Cats

Dogs in guest areas

The Finca's dogs do not enter food-preparation or kitchen areas. They are trained not to remain

within the dining and buffet areas, and guests are asked not to call or encourage them into those

spaces. The same principle applies to visiting animals: animals brought onto the property should

not be kept within areas being actively used for dining or food service.

The dogs are accustomed to the operation of the Finca and are well trained around guests and

food. They do not approach buffet tables or attempt to take food from tables.

Nevertheless, Finca Astronómica is their home and an open rural property. A dog may

occasionally cross the terrace or another guest area while moving around the Finca, checking its

surroundings or responding to something elsewhere on the property.

Crossing an outdoor service area is different from being allowed to remain around, approach or

interfere with food.

The Finca's dogs are regularly cared for and maintained to an appropriate standard of cleanliness

and general animal hygiene.

Cats in guest areas

The cats at Finca Astronómica are well cared for and maintained, but they remain cats: they

climb, jump, explore elevated surfaces, move between areas and choose resting places according to their own preferences.

They may therefore be seen sleeping on outdoor furniture, on the piano, or on the bar counter

when it is not being used for food service. They may also jump onto or cross outdoor tables or

other furniture.

This behaviour is not treated as permission for cats to interact with food. Cats are not

intentionally allowed onto surfaces while food is being served there, and they are not permitted

to walk amongst buffet dishes, eat from guest food or interfere with food service.

A cat may sometimes choose the bar as a resting place outside service periods. Before a surface is subsequently used for food or drink service, it is cleaned as appropriate. The same principle

applies if a cat has walked or rested on a table or another surface that will later be used for food

service.

If an animal accesses a relevant surface after it has been prepared for food service, the affected

surface must be cleaned again before food is placed or service continues there.

Cats may also choose to sleep or sit on furniture close to the buffet or dining area, including the

piano situated within the covered terrace area. Physical proximity of a healthy domestic animal

to a dining area is not equivalent to contamination of food.

Because the dining area is outdoors, a cat may occasionally jump onto or cross a table occupied

by guests. This is discouraged, but it cannot reasonably be represented as behaviour that will

never occur in an environment where free-ranging cats live. Guests should not encourage cats

onto dining tables or feed them from tables, plates or buffet food.

Three different situations

Finca Astronómica distinguishes between three fundamentally different situations:

Animal presence - an animal is somewhere within the wider outdoor environment.
Animal contact with environmental furniture or surfaces - for example, a cat sleeping on an outdoor bar or crossing a table outside food service. This requires cleaning where the surface will subsequently be used for food.
Animal contact with food or prepared food-contact surfaces - this is not accepted. Affected surfaces or equipment require cleaning, and contaminated food must be removed from service.

Animals are allowed to behave like animals. Food hygiene is managed like food

hygiene. The two principles can coexist.

Finca Astronómica does not promise an animal-free hospitality environment. It provides a

managed rural environment in which domestic animals are present and appropriate controls are

applied wherever their presence becomes relevant to hygiene or food safety.

Animal Roles, Communication & Sound

A living ecosystem makes sound

Finca Astronómica is located in a rural environment containing agricultural properties, domestic

animals, wild animals and protected natural areas. A consequence of choosing to preserve and

participate in that environment is that it has a natural soundscape.

Dogs bark. Roosters crow. Guinea fowl call. Peacocks call. Geese vocalise. Birds communicate with one another across considerable distances. Wild animals make sounds. Insects become

particularly noticeable after sunset.

These sounds are not artificial entertainment introduced into the Finca, nor are they necessarily

evidence of distressed or badly managed animals. Vocal communication is a fundamental part of

animal behaviour.

Animals use sound to communicate social information, maintain contact, announce their

presence, defend territories, warn of perceived threats and respond to changes within their

surroundings.

Finca Astronómica therefore does not operate according to the principle that a well-managed

rural property should be a silent property.

Silence and tranquillity are not the same thing.

The absence of traffic, urban activity and artificial noise allows natural sounds to become

considerably more noticeable. That is part of experiencing a rural environment rather than

evidence that the rural environment is malfunctioning.

Why we deliberately maintain an animal community

The species living at Finca Astronómica have not been selected simply to create a collection of

interesting animals. Different species perform different functions, and importantly, they perform

those functions together.

Some forage. Some consume organic material. Some control insects and other invertebrates.

Some alert. Some deter. Some provide physical protection. Some contribute manure and

nutrients. Some help manage vegetation.

The result is not a series of isolated animals but an interacting rural system.

A small bird may detect and announce a disturbance. A larger animal may investigate it. Dogs

respond to activity around the property's boundaries. Cats control smaller animals around

buildings. Poultry forage through the ground layer. Organic material becomes food, manure

becomes a resource, and nutrients return to the soil.

The animals therefore occupy different ecological and practical niches.

Dogs: protection, warning and territorial awareness

The dogs at Finca Astronómica are companion animals, but they also have an important working

role.

The Finca is a rural property containing people, animals, equipment and infrastructure, adjacent

to large areas of countryside. The dogs provide an additional layer of awareness and protection.

For this reason, barking is not behaviour that we attempt to eliminate entirely.

Dogs naturally bark when they detect unfamiliar people, animals, vehicles, movements or sounds

around their territory. Appropriate alert barking is useful behaviour on a rural property, and the

Finca's dogs are permitted and encouraged to alert when they perceive something that may

require attention.

This does not mean that uncontrolled or continuous barking is an objective. It means that a dog

giving an alarm is performing one of the functions for which dogs have lived alongside human

settlements for thousands of years.

Astronomy assistance dogs

The dogs at Finca Astronómica are not only companion animals or protection dogs. They are

trained to participate in astronomical activities and perform practical functions alongside our

astronomers.

Astronomy creates an unusual working environment: we deliberately work in darkness.

Ordinary white lighting is restricted during observations because it destroys dark adaptation and

interferes with both visual astronomy and astrophotography. Staff therefore cannot manage a

group at night in exactly the same way that they would manage visitors during a daytime activity.

The dogs provide an additional layer of awareness.

They are taught to become familiar with the group at the beginning of an activity. They approach

and interact with guests, including sniffing and greeting them, allowing the dogs to recognise the

people who are currently part of their environment. They subsequently remain around the group

and monitor its movement.

If somebody moves away from the main group, the dogs will often notice and may follow or

accompany that person. This is particularly valuable with children, whose movements during

activities require additional awareness in darkness.

Their role is not to replace human supervision. Rather, they provide an additional set of eyes,

ears and senses in an environment in which human vision has deliberately been restricted.

This becomes even more important when Astronomy Tours operates away from Finca

Astronómica. Astronomical observations and astrophotography frequently take place at remote

dark-sky locations where there may be virtually no artificial illumination, few buildings, little

passing traffic and considerable distance between the observing site and other people.

In these circumstances, the dogs help maintain awareness of the group and its surroundings.

They can accompany somebody moving away from the principal observing area, alert staff to

unusual movement or activity and provide both reassurance and deterrence in an isolated

location.

They also assist with astronomical equipment. Telescopes, mounts, cameras, computers and

astrophotography systems may remain operating outdoors for long periods, sometimes at some

distance from the astronomers themselves. The dogs can remain around deployed equipment and provide an obvious deterrent against interference or theft while continuing to monitor the

surrounding area.

Their hearing and sense of smell also provide environmental information unavailable to the

astronomers working beside them. A dog may detect an approaching person, animal or vehicle

long before somebody concentrating on a telescope in darkness becomes aware of it.

This also explains why the dogs are normally present with the group rather than routinely being

confined elsewhere during astronomical activities.

Their presence is functional. Their observation is functional. Their movement

around the group is functional. Appropriate alert barking is functional.

For this reason, we describe them as our astronomy assistance dogs. This is a descriptive role

within Finca operations and does not imply a legally recognised disability/service-animal status.

They are not a replacement for astronomers, guides, responsible adults or normal safety

procedures. They are another layer within those procedures - and one particularly well adapted

to working when humans have voluntarily turned the lights off.

Guinea fowl: biological pest control and an alarm system

Guinea fowl are active ground foragers and consume a wide variety of invertebrates. They are

consequently valued on farms as part of biological pest management, including helping to reduce

populations of ticks and other unwanted invertebrates.

Their second characteristic is considerably more obvious to visitors: guinea fowl are loud.

That is not an accidental defect in an otherwise useful bird. Their vigilance and conspicuous

alarm calls are among the reasons guinea fowl have historically been valued around farms and

rural properties.

They are highly alert to unusual movement and disturbances. When something unfamiliar enters

or approaches their environment, they frequently notice it and announce it very effectively.

Within a mixed group of animals, that alarm has value beyond the guinea fowl themselves. Other

animals can respond to the warning and investigate or take defensive action.

Their noise and their protective function are therefore intimately connected.

Peacocks: territory, pest control, culture and science

Peafowl have a long association with rural properties and estates and are also familiar within the

landscape and cultural environment of the Cartagena area.

At Finca Astronómica, their role has several dimensions. They are highly visible and vocal

animals. Their calls can announce disturbances and contribute to the wider warning network

between animals on the property. They are also opportunistic foragers and consume insects and

other small animals, contributing to the biological management of the environment.

The peacock also has a particularly interesting role within our educational philosophy.

The peacock has carried powerful symbolism across multiple ancient cultures. Its tail, covered

with apparently eye-like patterns and associated with the heavens, immortality and celestial

imagery, has appeared repeatedly in mythology, art and historical representations of the cosmos.

The extraordinary colours of a peacock feather also provide an immediate demonstration that

science is present in ordinary natural objects. Much of the brilliant colour of peacock plumage

does not arise simply from pigments. Microscopic structures within the feather interact with

light, producing structural colour and iridescence through optical effects involving interference

and the feather's highly ordered microscopic architecture.

Change the angle between the feather, the light and the observer, and the apparent colour

changes. The same fundamental physics of light that we investigate when discussing spectra,

diffraction, interference and astronomical instruments can therefore be encountered in a feather

held in someone's hand.

Science is all around us. The first scientific instrument is observation.

Roosters, chickens, ducks and other poultry

Roosters communicate naturally through vocalisation. Crowing is associated with territorial and

social communication and follows strong daily biological rhythms. Although the stereotypical

image is a rooster crowing at sunrise, roosters are perfectly capable of crowing at other times in

response to environmental and social stimuli.

Hens, ducks and other poultry have additional practical roles as effective foragers and consumers

of suitable organic material. They consume insects and other small invertebrates while moving

around the property and can use appropriate food material that might otherwise become waste.

Humans inevitably drop food. Crumbs, pieces of bread, vegetables and other suitable material fall

underneath tables and onto outdoor surfaces regardless of how carefully an area is maintained.

Once food service has finished and the area is appropriate for animal access, poultry can forage

for suitable remnants as part of their normal behaviour. They simultaneously consume insects

and other invertebrates attracted to organic material.

This does not replace normal cleaning. It complements it as part of the biological system

operating on the property.

Geese and other alarm animals

Where geese are present, their value extends beyond grazing and foraging. Geese are famously

vigilant and territorial animals. Their strong vocal response to unfamiliar movement has resulted

in their historical use as alarm animals around farms, properties and other sites.

Like guinea fowl, they demonstrate an important principle of the Finca's animal system:

protection does not have to depend upon a single species.

Food leftovers and the Finca's resource cycle

One of the most practical functions of the animals is the recovery of appropriate food material.

Finca Astronómica aims to minimise avoidable organic waste.

After meals, suitable leftovers can be separated according to what can appropriately be

consumed by different animals. Different materials are therefore separated rather than

indiscriminately mixing everything together.

Material suitable for one group of animals may not be suitable for another, and material

unsuitable for animal consumption follows a different route.

The objective is not simply to give leftovers to the animals. It is to identify which resources can

safely remain within the biological system of the Finca.

Suitable food becomes animal nutrition. Animals produce manure and other organic material.

Appropriate organic material contributes to compost and soil improvement. That soil supports

vegetation and cultivated areas.

The objective is to retain useful biological resources within the system for as long as reasonably

possible rather than automatically treating them as rubbish.

The animals operate as a system

It is therefore misleading to evaluate every species at Finca Astronómica in isolation.

The chickens and ducks that forage efficiently are themselves vulnerable animals. Guinea fowl

can provide an early alarm. Peafowl and geese contribute additional vigilance. Cats occupy

another ecological niche. Dogs provide substantially greater territorial awareness and physical

deterrence.

The animals communicate, react to one another and modify their behaviour according to what

the other animals are doing.

Mixed-species information networks exist throughout nature. Animals routinely respond not only

to signals from their own species but also to the alarm calls and behaviour of other species

sharing their environment.

The Finca allows those relationships to function rather than attempting to manage every species

as an isolated exhibit.

Natural sound is part of coexistence

The consequence is unavoidable: some of these animals make noise. Indeed, in several cases

making noise is part of their function.

Removing every animal that barks, crows, calls or sounds an alarm would not constitute

successful coexistence with a rural ecosystem. It would mean progressively removing the

ecosystem whenever its natural behaviour became inconvenient.

We manage animal welfare, hygiene, safety and genuinely problematic behaviour. We do not

attempt to suppress normal biological behaviour merely because it is audible.

Visitors to a rural astronomical facility should therefore expect a natural rural soundscape

alongside the dark sky: birds, insects, dogs and other animals may all occasionally be heard.

The darkness that makes astronomical observation possible and the living countryside

surrounding that darkness are part of the same environment.

Science is all around us

The animals of Finca Astronómica ultimately demonstrate the same principle as the telescopes.

Science begins by noticing what is happening.

Why does the guinea fowl suddenly call? Why does another animal react to it? Why does a

rooster keep time without a clock? Why does a peacock feather change colour when we rotate it?

Why do insects appear around one ecological resource and disappear when another animal

begins foraging there? Why do different species cooperate without anyone teaching them to?

Looking through a telescope is one form of observation. Looking carefully at the living world

immediately around us is another.

The objective of science education is not simply to accumulate facts. It is to stop treating the

world as a collection of unrelated things and begin recognising the systems connecting them.

2. Sustainability, Resources & Staying at the Finca

Overnight stays at Finca Astronómica

Why we provide places to sleep

Finca Astronómica is not a hotel, resort or conventional holiday-accommodation business.

The yurts and glamping pods exist primarily because astronomy does not operate according to normal daytime schedules.

Astronomical observations may continue late into the night. Particular objects may only become observable at certain hours. Planetary observations can require waking before sunrise. Meteor showers, conjunctions, eclipses and other phenomena occur when celestial mechanics determine that they occur - not when it is convenient for hotel check-in and check-out times.

Astrophotography creates another requirement. An imaging sequence can continue automatically for several hours while a telescope collects light from the same astronomical target. There is little value in requiring an astronomer, student or visitor to sit beside the equipment for those hours simply because there is nowhere appropriate to rest.

For people travelling some distance to participate in an Astronomy Night, being able to sleep before driving home can also be considerably more sensible than immediately beginning a long journey after a late night of observation.

The accommodation at Finca Astronómica developed in response to those realities.

Accommodation in support of astronomy

Our overnight facilities should therefore be understood as accommodation supporting astronomical activity.

They provide somewhere comfortable and sheltered to sleep, rest between observations or remain overnight when astronomical activities continue across different parts of the night.

A visitor might participate in an evening observation, sleep for several hours and wake again before dawn for planets or another astronomical phenomenon. An astrophotographer may start an imaging sequence, leave the equipment operating and sleep while photons continue accumulating. Another guest may simply prefer to sleep after a long Astronomy Night and leave the following morning.

The accommodation exists around the astronomy rather than the astronomy existing around the accommodation.

Glamping pods

The glamping pods are deliberately small and simple. Their purpose is to provide a private, comfortable place for basic overnight rest without introducing the infrastructure, resource consumption and environmental footprint associated with conventional hotel accommodation.

They are sleeping spaces, not hotel rooms. Their compact size reflects their function: somewhere to sleep, store essential personal belongings and rest between astronomical activities.

Guests booking a pod should expect simple astronomical accommodation in a rural environment, rather than the space, facilities or service structure of a hotel room or holiday apartment.

Yurts

The yurts provide a different style and somewhat larger form of overnight accommodation while following the same underlying principle.

They allow guests to remain within the astronomical environment of the Finca and sleep close to the observing facilities rather than leaving the site at the end of the activity.

A yurt is nevertheless still a yurt. It should not be interpreted as a conventional hotel bedroom simply because it contains beds and is available for overnight use. Its construction, relationship with the outdoor environment and facilities are fundamentally different. That difference is intentional.

Staying at the Finca is part of an astronomical visit

An overnight booking should not be understood as purchasing a conventional hotel stay with astronomy added as an optional evening activity. The relationship is the reverse.

The astronomy is the reason for the overnight facilities.

The pods and yurts extend what is possible during an astronomical visit by allowing people to remain on site through the night. They make observations at unusual hours practical, allow rest during long astrophotography sessions, allow guests to wake for astronomical events before dawn, and make multi-stage observations possible without repeatedly travelling between the Finca and external accommodation.

Arrival and use of the accommodation

Because the accommodation supports the astronomical programme, Finca Astronómica does not operate around conventional hotel-style check-in.

Guests should not expect to arrive many hours before an activity simply because they have booked somewhere to sleep that night.

Arrival, access to accommodation and departure are organised around the relevant activity and the operation of the Finca.

The booking therefore provides overnight accommodation associated with the astronomical visit, not unrestricted occupation of a holiday property for a conventional tourism day.

Expectations and simplicity

The appropriate expectation is deliberately straightforward: a clean, comfortable and unusual place to sleep at an astronomical facility in the countryside.

Guests should not expect conventional hotel-room dimensions, hotel reception or concierge services, resort facilities, unrestricted early check-in, the infrastructure of an apartment or holiday home, or the level of resource consumption associated with conventional hotel accommodation.

What they gain instead is the ability to sleep at the observing site itself, wake when the sky requires it, and remain immersed in the astronomical environment throughout the night.

Providing somewhere to sleep does not automatically require constructing conventional buildings, creating large climate-controlled rooms or dramatically increasing the consumption of water, electricity and other resources.

We provide what the activity genuinely requires rather than consuming resources simply to imitate a conventional hotel.

Observe, rest, wake, and look at the sky again.

Water, Wastewater & Toilets

Water is a resource, not simply a utility bill

Water conservation at Finca Astronómica is not primarily about reducing the cost of water. It is about reducing the consumption of a limited natural resource.

In an urban environment, opening a tap can create the impression that water is effectively unlimited: it arrives through the municipal network and disappears through another pipe after use.

An off-grid rural property operates much closer to the physical reality of the resource. Water has to come from somewhere. It has to be transported, collected, stored or produced. Storage has limits. Supply has limits. And after water has been used, it does not magically disappear. It has to go somewhere.

Water in a dry Mediterranean environment

Finca Astronómica operates in the dry Mediterranean environment of the Region of Murcia and within the wider environmental context of the Mar Menor basin.

Water availability and water management here cannot reasonably be approached as though the Finca were situated in a high-rainfall region with effectively unlimited municipal supply and sewerage infrastructure.

Many rural properties in the area cannot simply consume arbitrary quantities of water. Natural rainfall is limited and irregular. Water storage has physical limits. Producing, transporting or obtaining additional usable water requires infrastructure and resources.

The relevant question is not merely 'Can we obtain more water?' It is also 'Do we actually need to use that water in the first place?'

Water does not disappear after use

Every litre of water entering a property eventually has to leave it, remain stored, evaporate, be incorporated into biological processes or be appropriately managed as wastewater.

Therefore, excessive water consumption creates an output problem as well as an input problem.

Finca Astronómica cannot simply take large quantities of clean water, use them once and indiscriminately discharge the resulting wastewater onto the surrounding land.

This is especially important within the environmental context of the Mar Menor basin, where responsible management of water, nutrients and discharges is particularly significant.

Water management means considering the entire cycle: supply -> storage -> use -> recovery -> treatment -> reuse or appropriate disposal.

The Finca's water-management system

Finca Astronómica has progressively developed its own water-management and conservation infrastructure as part of its off-grid operation. The system continues to evolve.

Our objective is not simply to install one technical solution and declare the water problem solved. We continually explore practical ways of reducing unnecessary water consumption, increasing storage capacity and resilience, improving efficiency, recovering water where appropriate, separating different water uses, managing wastewater responsibly, recycling suitable wastewater where technically and environmentally appropriate, reducing unnecessary discharge, and developing new solutions as the Finca and its activities evolve.

Off-grid operation encourages something that conventional infrastructure can easily hide: resources have physical limits.

Why there are no guest showers

The absence of guest showers at Finca Astronómica is deliberate. It is not an accidental missing hotel amenity.

Showers create one of the largest discretionary water demands associated with overnight accommodation. They also immediately generate a corresponding volume of wastewater that must subsequently be managed.

Providing conventional unrestricted shower facilities for overnight visitors would therefore require substantially increasing both the Finca's water supply and its wastewater-management capacity. That would contradict the purpose of providing simple accommodation supporting astronomical activities.

The combination of limited water resources, off-grid operation, water conservation, wastewater management, environmental responsibility within the Mar Menor basin, and the intentionally simple nature of astronomical overnight accommodation is therefore the principal reason guest showers are not provided.

Creating a sustainable place to sleep does not require creating a hotel bathroom beside every bed.

Drinking water

Conservation of water used for infrastructure does not mean compromising access to safe drinking water.

Drinking water provided to guests is supplied in bottles through a water supplier. This separates potable drinking requirements from the wider technical water-management systems operating on the property.

Cleaning does not always require water

Responsible water management also influences how outdoor areas are cleaned.

Dry leaves, dust, feathers, loose material and many forms of dried animal waste can often be removed mechanically without introducing water and cleaning chemicals into the environment.

Depending on the surface and contamination involved, appropriate methods can include sweeping, vacuum or suction systems, blowing or other forms of dry mechanical removal. Where washing or disinfection is genuinely required, it can of course be used.

Using water and chemicals where they provide no meaningful additional hygiene benefit is not automatically better cleaning.

The objective is effective cleaning with the minimum appropriate environmental impact, rather than maximum water consumption.

Finca Astronómica does not have an urban sewer beneath it

The toilets at Finca Astronómica operate as part of an independent wastewater system.

Waste does not enter a municipal sewer network where kilometres of infrastructure and a large treatment facility take responsibility for whatever disappears down the toilet.

The Finca uses septic/wastewater-management infrastructure with finite physical capacity and specific biological and mechanical requirements. What enters the toilet therefore matters.

The toilet is part of a biological system

A septic system is designed to receive the materials associated with normal toilet use and appropriate toilet paper. It is not a general waste-disposal system.

Items that do not break down appropriately can obstruct pipes, damage components, interfere with treatment, accumulate within the system and create failures requiring physical intervention and removal.

This includes:

wet wipes, including products marketed as flushable;
nappies/diapers;
sanitary products;
tissues and other paper products not intended for septic toilet use;
cloth;
plastics;
packaging;
excessive quantities of paper;
other solid waste.

The fact that an object physically fits into a toilet does not mean that the wastewater system can process it.

Why the toilet rules matter

Damage to an off-grid wastewater system is not equivalent to blocking a toilet in a hotel room. A blockage or septic-system failure can affect the sanitation infrastructure available to the entire property.

Repair can require opening pipes, pumping systems, removing accumulated foreign material or temporarily taking facilities out of service.

For that reason, instructions concerning toilet use are operational requirements, not arbitrary requests for convenience.

Guest responsibility

At present, Finca Astronómica relies primarily on clear information and cooperation from visitors. There is no practical mechanism capable of physically preventing somebody from placing a wipe, nappy, sanitary product or another inappropriate object into a toilet.

We therefore ask guests to follow the instructions provided and use the waste bins available for materials that must not enter the wastewater system.

Unfortunately, inappropriate materials continue periodically to be introduced despite these instructions, resulting in avoidable maintenance and damage.

If repeated misuse makes the present cooperative approach unsustainable, additional measures controlling the use, maintenance or availability of toilet facilities may eventually become necessary. Our preference is not to introduce unnecessary restrictions.

If it does not belong in the wastewater system, put it in the bin.

Resource use is part of visiting an off-grid Finca

Water conservation, simple overnight accommodation, the absence of showers and careful toilet use are not unrelated inconveniences. They are different consequences of the same operating model.

Water must be obtained and stored. Electricity must be produced. Wastewater must be managed. Solid waste must be processed or removed.

Everything consumed by the property has a physical origin, and everything discarded has a physical destination.

Sustainability begins when resources stop being treated as though they appear from nowhere and disappear when we have finished with them.

Electricity & Energy

An off-grid energy system

Finca Astronómica operates off grid.

Our principal source of electricity is solar energy. The Finca has its own photovoltaic installation and energy-storage system designed to provide the electricity required for normal operation of the property and its astronomical activities.

On most days, solar production and stored energy provide what the Finca needs. But being off grid does not mean having an unlimited supply of electricity.

Every unit of electricity consumed at Finca Astronómica first has to be produced and, when it is not used immediately, successfully stored.

There is no conventional electricity grid sitting invisibly behind the property to provide unlimited additional power whenever consumption increases. This makes energy management an essential part of operating the Finca.

Solar production naturally varies

Solar panels do not produce the same amount of electricity every day. Production depends on environmental conditions including available sunlight, cloud cover, season, length of day and the temperature of the photovoltaic panels themselves.

A cloudy day can significantly reduce production. Extremely high temperatures can also reduce photovoltaic efficiency.

At the same time, energy consumption varies. An Astronomy Night with many visitors requires electricity for the operation of the property, bar and food-service infrastructure, water pumps, toilets and wastewater systems, refrigeration, astronomical equipment, computers and other systems.

The electricity demand does not end when the last telescope observation finishes.

The Finca still has to work after the guests go to bed

After an activity, the property has to be restored and prepared. Dishes must be washed. Food-service equipment has to be cleaned. Refrigeration continues operating. Water and wastewater pumps may continue to be required. Toilets continue being used by overnight guests. Equipment may remain operational, particularly during astrophotography.

This can create a substantial electricity demand precisely when the Sun is no longer producing electricity.

Normally that demand is supplied from energy stored during the day. However, after a day of unusually low solar production, unusually high consumption or a combination of both, stored energy may not be sufficient to safely operate everything required throughout the night.

That is why the Finca also has backup generation.

Generator use

A generator provides resilience to the off-grid energy system. We deliberately minimise its use because our preferred energy source is solar power.

Nevertheless, there are circumstances in which running the generator is necessary to maintain essential operations, protect the electrical system or replenish energy reserves.

This may particularly occur after prolonged or significant cloud cover, unusually low solar production, exceptionally demanding activities, unusually high electricity consumption, periods of extreme environmental conditions, or a combination of substantial daytime and nighttime energy demand.

Generator operation may therefore occasionally occur during the late evening or night.

Generator noise and overnight guests

A generator is mechanical equipment and consequently produces sound. We understand that somebody sleeping at the Finca would generally prefer not to hear it, and unnecessary nighttime generator operation is avoided wherever reasonably possible.

However, the Finca cannot guarantee that the generator will never need to operate during an overnight stay.

The accommodation exists within a functioning off-grid astronomical facility. If available stored electricity is insufficient to maintain essential systems, protecting the operation of those systems takes priority over maintaining absolute silence.

Off-grid living does not eliminate infrastructure. It makes the infrastructure visible.

Responsible electricity use by guests

Because electricity is locally produced and stored, guest consumption also matters.

Overnight accommodation includes reasonable access to electricity for ordinary low-consumption personal devices, such as mobile phones, tablets, laptops, cameras, small battery packs and comparable personal electronics.

This does not constitute unrestricted access to the Finca's electrical system for arbitrary electrical appliances or equipment. Guests should not bring high-consumption devices and assume they can simply be connected to the Finca's electricity supply.

Where specialist equipment is genuinely required for an astronomical, accessibility or other agreed purpose, its electrical requirements can be considered separately.

At an off-grid property, electricity is a managed resource rather than an unlimited utility.

Why the glamping accommodation does not have air conditioning

The glamping pods are not equipped with conventional air-conditioning systems.

Air conditioning creates a substantial and sustained electricity demand. Installing individual air-conditioning systems throughout simple overnight accommodation would dramatically increase nighttime energy consumption - precisely when photovoltaic panels are no longer producing electricity.

Meeting that additional demand would require substantially more generation, battery storage and potentially more frequent use of backup generation. That would contradict both the environmental philosophy of the Finca and the purpose of the accommodation itself.

The pods exist to provide simple rest in support of astronomical activities. They are not intended to reproduce climate-controlled hotel rooms in a rural field.

Sustainability is not simply replacing the power source

Sustainability does not mean taking exactly the same level of consumption expected in a resource-intensive environment and merely attempting to power all of it with solar panels.

The first question should be whether that consumption is necessary. Producing renewable electricity matters. Using less electricity when it is unnecessary matters too.

Produce responsibly, store intelligently, consume deliberately, and use backup generation when reality requires it.

Real renewable-energy systems operate within physical constraints. The Sun does not shine equally every day. Batteries have finite capacity. Equipment requires energy. Weather changes. People consume resources. And occasionally a backup system is necessary.

Resources are available to be used responsibly - not because they are infinite, but precisely because they are not.

3. External Food & Drinks

Why external food and drinks are not permitted

External food and drinks are not permitted at Finca Astronómica, with the exception of personal drinking water.

This rule exists primarily for participant safety, animal welfare, hygiene, waste management and the responsible operation of the Finca.

It is not based on an expectation that visitors should arrive hungry or be forced to purchase everything separately from the bar.

Where an activity is long enough to require a meal, appropriate food is included or otherwise organised as part of the activity. Depending on the programme, this may be dinner, lunch or another appropriate meal.

Short activities that do not extend across a normal meal period may not include food because there is no practical need for it.

Drinking water is always available. Many Finca experiences additionally include access to drinks such as lemonade, tea and coffee according to the particular activity.

A bar operates for guests wishing to purchase additional drinks, snacks and other products selected and approved by Finca Astronómica.

The intention is therefore to provide for the reasonable food and drink needs of visitors without introducing uncontrolled food into the environment.

Food safety and allergen control

Food brought onto the property from unknown external sources creates something Finca Astronómica cannot adequately control.

We do not necessarily know its ingredients, how it was prepared, how it has been transported, how long it has remained unrefrigerated, how it has been stored, what allergens it contains, what surfaces or other foods it has contacted, or what happens to it after the person bringing it has finished eating.

This becomes particularly important in a group environment. A product brought for one person's consumption can be shared with somebody else. Food can be left on a table. Children can exchange snacks. Crumbs and pieces of food can fall onto common surfaces.

Once uncontrolled food enters a shared environment, Finca Astronómica can no longer reliably manage all of the risks associated with it. Restricting external food substantially reduces those uncontrolled variables.

Protecting the animals

Human food is not automatically animal food

One of the most important reasons for the rule is animal safety.

Food brought onto the property does not necessarily remain with the person who brought it. It can fall underneath a table, be dropped while somebody walks, be left behind, be deliberately given to an animal, be taken by an animal when somebody is distracted, or become accessible later after guests have left an area.

For this reason, even food intended exclusively for human consumption can become an animal-welfare issue.

Many foods routinely consumed by people are inappropriate or potentially dangerous for particular animal species. Even where a food is not directly toxic, uncontrolled additional feeding can interfere with managed diets, digestive health, weight, medication or other aspects of animal care.

Our animals' diets are managed

Animal nutrition at Finca Astronómica is actively managed rather than left entirely to random feeding by visitors.

The Finca team includes specialist knowledge in animal dietetics, and the diets and nutritional requirements of our animals are monitored accordingly.

Different species have different requirements. The fact that some Finca animals participate in the recovery of suitable food material does not mean that they can eat arbitrary leftovers.

Suitable food remaining after Finca-managed meals is separated according to what can appropriately be consumed by particular animals. That separation is controlled by us. Food brought independently by visitors bypasses that system completely.

Do not bring treats for our animals

External animal food is also prohibited.

Guests should not bring dog treats, cat treats, bird food, bread for poultry, biscuits, sweets, animal snacks or any other food intended to be given to Finca animals.

Animals may be friendly, interested and extremely convincing when attempting to obtain food. This should not be interpreted as nutritional advice from the animal.

Please do not feed Finca animals unless a particular interaction has been specifically authorised and supervised by the Finca team.

Cleanliness and waste

External food also creates packaging, bottles, wrappers, crumbs, spills and leftovers.

In a large outdoor environment, these materials do not remain neatly confined to one table. Wind moves lightweight packaging. Liquids spill. Food falls. Children drop things. Adults drop things. Animals investigate. Insects are attracted.

The issue is therefore not simply whether a visitor personally intends to put their rubbish into a bin.

The more uncontrolled material introduced into the property, the more uncontrolled waste has to leave it.

Reducing what enters the Finca is one of the simplest ways of reducing waste, cleaning requirements and unnecessary environmental impact.

Alcohol

Guests may not bring their own alcoholic drinks onto Finca Astronómica.

Where alcohol is available, it may be purchased through the Finca bar. This allows the Finca to retain control over alcohol being supplied and consumed during its activities.

Astronomy Nights take place in darkness, around specialist equipment, uneven outdoor environments, animals, families and other participants. Responsible alcohol management is therefore also a matter of safety and the experience of other guests.

The existence of alcohol at the bar does not create an entitlement to purchase unlimited alcohol.

Finca staff may refuse the sale or further service of alcohol whenever they consider it appropriate.

External alcohol remains prohibited regardless of whether the same or a similar product happens to be available from the bar.

Food and drinks in overnight accommodation

External food and drinks, other than drinking water, should not be taken into the glamping pods or yurts.

The accommodation is intended primarily for sleeping and resting during or following astronomical activities.

Introducing food into sleeping accommodation creates additional problems including crumbs and spills, insects, attraction of animals, odours, staining, additional waste and unnecessary cleaning.

Food and drinks are available through the designated dining and bar facilities rather than being consumed or stored within sleeping accommodation. Drinking water is permitted.

Personal water

Guests may bring their own drinking water. However, doing so is generally unnecessary because drinking water is provided at Finca Astronómica.

The exception exists simply because access to personal drinking water should never depend upon purchasing something from the Finca.

Medical, dietary and other genuine requirements

The prohibition on external food is not intended to create a health risk for somebody with a genuine medical or exceptional dietary requirement.

Where a person needs to carry or consume something specific for medical reasons, severe allergies, infant needs or another requirement that cannot reasonably be accommodated through the normal Finca provision, this should be discussed with Finca Astronómica in advance whenever possible.

An agreed exception does not convert the general rule into permission for a group to bring additional food and drinks.

The underlying principle

Finca Astronómica already assumes responsibility for providing food and drink when the duration and nature of an activity require them.

In return, we ask visitors not to introduce additional uncontrolled food, drinks or animal feed into the property.

This allows us to manage what enters the Finca, what people consume, what animals can access, what becomes waste and what ultimately leaves the Finca.

That is simultaneously a food-safety policy, an animal-welfare policy, a cleanliness policy and a sustainability policy.

If we control what enters the system, we can take responsibility for what happens to it afterwards.
