San José, Costa Rica


Costa Rica is home to stretches of lush turtle nesting beaches all along its unspoilt coastline. In such a tropical paradise, it is hard to imagine the extinction of the turtles, however the sea turtle population is rapidly plummeting. Due to natural predation from animals and severe human interference such as turtle egg poaching, industrial fishing and selling turtle shell products, all turtle species from the Pacific Coast are, to some degree, in danger of becoming extinct.

Working alongside an influential NGO, the local community and other volunteers, you will be protecting nesting turtles and their eggs, and ensuring that more adult and baby turtles can make it safely to the sea. The hard work of volunteers over the past few years has resulted in the survival of thousands more turtles.

What will I be doing?

As a Costa Rica turtle volunteer, your project tasks can include, but are not limited to:

  • Beach patrols and data collection
    By night you patrol the beaches, watching for nesting turtles coming up out of the sea. This is an incredible sight – one which many volunteers will never forget. Research and measurements on the turtles are recorded, and the eggs transported to a hatchery, where they can hatch in safety. This all takes place under the Milky Way, seen in incredible clarity due to the lack of light pollution ( beginning of season and through to November).
  • Working in the hatchery
    By day and by night you check the hatchery for hatching turtles. As the turtles hatch, you collect data on the incubation period and hatching success rate. The research is linked to a worldwide study, and helps with global campaigns to end industrial fishing close to land. Baby turtles generally start hatching from mid August onwards.
  • Helping around your new home
    You will also be asked to do a few chores around the project house to keep it clean and tidy. Local children often pop by to practice their English and coax you into some of their games – you are encouraged to join them!
  • Conservation projects
    An important role for you as a sea turtle conservation volunteer is preserving the turtle’s nesting habitat and educating local people about the importance of this task. You can be helping with beach and land clean ups, teaching local children about sea turtle conservation, helping with a reforestation programme and assisting with any ad hoc research and data collection tasks. There is also the opportunity to travel to a local fishing village to learn about sustainable fishing, have lunch with the locals and take a mangrove tour.

When can I go?

  • The project is open from July – December, the turtle nesting season
  • Mother turtles can be seen throughout this period – nature permitting of course!
  • Baby turtles start hatching from mid August onwards

Where will I be based?

There are two project sites close together. Volunteers are accommodated in one of the two similar beach projects depending on volunteer numbers and where you are needed the most.

  • The paradise beach project: A buzzing little community of both Costa Ricans and American expats, this project site has a stunning white sand beach and plenty to keep you busy, with an excellent surf school and other outdoor activities, and lots to explore. Find out more…
  • The tropical beach project: A close-knit community of about 100 residents. The beach is stunning, lined with coconut trees and facing a small fishing port over the estuary. This is a beautiful base, with great access to the beach, excellent surfing, strong community ties and a real opportunity to work with locals and improve your Spanish. Find out more… This beach operates for those families in upgraded accommodation.

More Information

The main aim of the project is to increase the number of baby turtles that will survive from each nest. It is generally believed that, for every 1000 turtles born, just two will survive until adulthood. Through aiding the hatching process and making sure that the baby turtles make it to the sea safety, the volunteers are helping to reduce that staggering statistic.

The predominant role of the volunteer is the exciting nightly beach patrol. The beach patrol is generally organised into two shifts of about 3 hours and timings change depending on the tides.

The number of turtles that are born and that survive is on the decline. At the beach sites where turtle eggs are protected in hatcheries, approximately 80% of the eggs hatch and make it to the sea. In sites where there is no hatchery, maybe 15% of the eggs will hatch and make it to the sea. In beach sites with no protection whatsoever, the survival rate is even less. The difference here is quite staggering.

Turtle eggs, once laid, are at risk from all sorts of factors. Nests are endangered by racoons, coati, termites and skunks, and if it manages to make it to fruition, the baby turtle’s effort to reach the sea is often scuppered by vultures and crabs! Volunteering in Costa Rica means that you can help increase the number of turtles hatching and hence prevent a beautiful species from becoming extinct.

  • Beach patrols: Beach patrols take place at night time as this is when the turtles come out to nest. Patrols usually last up to 3 hours- they include walking up and down the beach looking for turtles and nests, recording data, taking the eggs to the hatchery and releasing baby turtles into the sea.
  • Hatchery monitoring: You will spend about 2 hours per day monitoring the hatchery, and this can be in the daytime or the night time. In busy times the hatchery is checked hourly for new babies emerging.
  • Releasing babies: This is an extra ordinary event to witness as you set little babies on a path to survival – which has of course been increased by your efforts! When all babies have emerged into their mesh protection circle, they are collected and counted and an average of 10 are weighed and measured. They are then released under the watchful eye of volunteers as they make their own way for the last couple of metres into the great ocean
  • Writing up data / cleaning equipment: You will spend some time each day writing up the data collected on the previous night’s beach patrol, and cleaning down the buckets, gloves and other items used on the patrols.
  • Nap time: Most people find that they like to take a nap at some point during the day. As your night’s will be slightly disrupted with the beach patrols, it is good to get in some extra sleep during the day.
  • Free time: Meals are served three times a day, and in between these you can explore the coastline, the rainforest, chill out in a hammock with a book and drink fresh coconut juice straight from the coconut. Village communities are centred round the football pitch, so there is plenty of opportunity to get involved with local games. You will find that you live a very laid back Tico lifestyle. Local trips can be arranged in advance of the day you want to travel. Sponsor a turtle or a nest and paint a personal sign – the team will give you updates on your hatchling date or if your turtle returns to nest again! Please note the ocean on this coast is strong and there are often riptides. Perfect for surfing but we recommend you go no deeper than waist height when standing. There are no lifeguards as this is not a tourist beach.

If  you’ve ever thought to volunteer abroad with animals or indeed volunteer sea turtles themselves, then this is the project for you.

The sad fact of the matter is that the turtle populations around the world are plummeting. Costa Rica turtle conservation gets you stuck in to actively protecting these vulnerable creatures. To volunteer with sea turtles, protecting adult and baby turtles, is not just an important thing to do, it is also a step in the right direction to preserving this species for generations to come.

The setting of these projects comes in a close second to why you should do this. Several of our volunteers over the years have chosen to travel Costa Rica either before or after the project- and each one has said that the project beaches were the most stunning that they have seen in the entire country. Patrolling the beach under the Milky Way, relaxing in a hammock beneath the palms, releasing baby turtles out to an azure sea… the location just makes this project unforgettable. Despite this beauty, the oceans have been filled with plastic and a lot of this washes up on the beach. It is amazingly satisfying to take part in the weekly beach clean up patrol.

Nesting season is from July until December. We take volunteers from the beginning of July until the middle of December.

Be aware that there are no hatchling until at least mid August but the laying season is still a very rewarding time as you get to see mother turtles up close and collect those precious eggs. Likewise, there are few nesting turtles at the very end of the season but the hatchling are popping out regularly! In the middle of the season (Sept/Oct) there are plenty of both!

  • August – October:  Green season. Generally high temperatures (20 – 30 degrees celsuius) with sunny mornings and wet afternoons. This is the peak time for nesting turtles, and baby turtles start to hatch from August onwards.
  • November – December: End of the green season / beginning of the high season. Generally high temperatures (20 – 30 degrees celsius). It can always rain in Costa Rica, but there is generally a bit less of it in November and December.   You can generally see nesting turtles into December, although the majority of sightings will be the babies that you are releasing.
  • There will always be a mixture of sunshine and rain. Nature cannot be guaranteed, so we would suggest booking the dates that work best for you and enjoying whatever happens!
  • There is turtle activity throughout July – December, whether it be with adults or babies (or both!).
  • The turtle nesting season is July – December, and mother turtles come to lay their eggs on the beach throughout this season. Sadly there are no guarantees that they come up every day however!
  • Baby turtles start hatching from mid August onwards, depending when mother turtles lay their eggs.

Whilst late-availability is possible, we would advise booking as soon as you can to guarantee your ideal dates. Our projects are very popular and spaces can fill up several months in advance, especially for the months of June to September.

  • Flexible: Working with nature means that things can change at the last minute – the timing of your beach patrol, the weather, dinner time. Pack a good dose of flexibility and you can’t go wrong. You will need to be prepared for interrupted sleep patterns but you’ll have plenty of time to catch it up with naps.
  • Positive attitude: We can’t guarantee lots of turtle sightings, we can’t guarantee that you won’t get a frog in the shower and we can’t guarantee beautiful weather. With a positive attitude however, you can guarantee a fantastic time for yourself doing turtle conservation volunteering. The location is stunning, the project is amazing and the opportunity is unique. Embrace it all!
  • Initiative: You may need to use your initiative to help on this project. The staff are there to support you, but the thinking and the action is all down to you.
  • Sociable: You will be living and working alongside other people. There is lots of fun to be had together, and your free time will be filled with lots of socialising.
  • Get up and go attitude: You will have lots of downtime on the project, and it is up to you to amuse yourself. If you want to take trips or do something with your day, it is up to you to arrange it and make it happen! The Costa Rican pace of life is much slower than you might be used to, so be prepared for a setback or two!

Turtles are greatly endangered around the world, and as such this project is created with their conservation and preservation in mind. There are several regulations in place to ensure that the preservation of the turtles is at the forefront:

  • When patrolling the beaches at night and a nesting turtle is seen, volunteers must remain quiet and only use the red lamp on their head torches.
  • When working around the nesting turtles, volunteers should remain quiet and conduct the research quickly and efficiently without disrupting the nesting turtle
  • Volunteers are not permitted to touch adult turtles unless asked to help with measuring. Babies must be handled with gloves at all times.
  • Eggs are transported from the site where they were laid to a protected hatchery to ensure greater hatching success rates
  • On hatching, baby turtles are kept together in one space until they are all hatched to preserve their energy.
  • Baby turtles are taken close to the edge of the sea for release. They must walk at least the final 10 metres to see independently of volunteers so that their muscles strengthen and their navigation is improved
  • Volunteers will not interfere with the baby turtles’ progress towards the sea.

Oyster assesses projects carefully to ensure that they offer high standards of animal welfare and environmental practice. We also check that volunteers understand key points of good practice before working with animals. To find out more, see our animal welfare policy.

The village spreads, with its 200 inhabitants, along the length of its 3.2km beach. This is a very small community, and you will soon become one of the locals. The local children in particular love coming to the volunteer house to practice some English and play games.

The beach is flanked on one end by cliffs with crashing waterfalls in rainy season- there are lovely rock pools and shells to be found at this end. At the other end is a mangrove swamp and the river estuary.

For proactive people, there are quite a few free time activities- surfing lessons, exploring the mangroves, playing football, basketball or volleyball with the locals, horse back riding on the beach or in the jungle, a trip to the local butterfly farm. In addition to these activities, the beach is beautiful- perfect for an afternoon of reading, walking or relaxing. You need to be proactive to get these things done however!

The beach has a small local community of approximately 100 inhabitants. It is rural, rugged and beautiful, stretching over 4.5km along the Pacific Ocean. To one end of the beach is a river that separates the paradise beach project and the tropical beach project. To the other end is a beautiful estuary facing on to a small fishing port. The surfing here is excellent.

Private upgraded family rooms with AC and a swimming pool are available alongside the main station house.

There are some really great community ties here, and the locals love to have the volunteers with them. The locals even help out with the beach patrols, offering a great cultural immersion and the opportunity to improve your Spanish.

There are always fun projects to be done, including painting signs, updating the hatchery and working with the community to promote the project. Most days the local children come by for English homework help or just for a quick soccer game in the yard. The community is excited to have the project and is always willing to help when needed.

We are an approved activity provider for the Duke of Edinburgh’s Award. You are able to put the time that you spend volunteering abroad on this project towards achieving your Gold Duke of Edinburgh’s Award. We are happy to sign off your completion of this programme to show that you have achieved the Residential section of the Gold Award.

We would recommend budgeting up to £50 per week for drinks, treats and trips.

There are no cash machines at the project sites so you will need to have all your money with you for your stay. The closest access to an ATM is an hour away with no regular transport. Costa Rican Colon is not available outside the country so it is best to change some as soon as you arrive. We recommend you take US Dollars to spend on larger purchases like tours and trips.

Typically you can stay as a visitor in Costa Rica for up to 3 months, although the exact period is at the discretion of the immigration officer on arrival. If you will be flying through the USA you will need to apply for an online ESTA visa before you leave.

You should make sure your passport is valid for the duration of your stay plus 1 day.

Most of our volunteers are independent travellers and you will become part of a group of people from around the world here. It is fine to travel with friends or as part of a small group too however- more the merrier!

The simple answer to this question is, yes absolutely!

It is important to bear in mind however that this may not be like other holidays that you have taken. Remember that you are volunteering, and this means that you will be put to work! This sort of holiday is a world away from sun loungers and cocktails, with our volunteers often heading home tired but immensely satisfied. If you think that you will need a bit of relaxing time on your trip too, do make sure to factor this in when your time on the project is complete.

You should visit your doctor or travel nurse to find out what vaccinations you will need. There are no compulsory inoculations necessary for Costa Rica but check with your doctor to make sure that your Polio, Typhoid, Hepatitis A and B vaccinations are all up to date. None of the project sites are in malaria risk areas, but getting anti-malarials is up to you, as there are areas in Costa Rica where malaria is found. You should follow your doctor’s advice.

Please see the Fit for Travel website or the UK government’s travel advice page for Costa Rica.

There is a mobile medical unit that comes through the villages, as well as a hospital within an hour of the project.

Costa Rica is considered to be one of the safest countries in Latin America. It is one of the few countries in the world not to have an army!  Transfers can be are included in this project, including travel to and from the airport, which means you avoid having to negotiate San Jose alone. However, if you do have time to spend in San Jose, you will find a lively and buzzing city. The guesthouse included in the transfer package we offer is based close to the city centre in a very safe area. We recommend that you return to the hotel before it gets dark as street lighting is a lot more limited than you might be used to.

At your project site you will be living in a small community which is very friendly and has known and supported this project for many years. The accommodation is lovely and right next to the beach with locks on the doors. The area is beautiful and locals love to show you the area.

The small communities where you will be living have around 200 people. They are approximately 5 hours from the city of San Jose. The closest town has the main head office, supermarket, bar and cafe. Volunteers can jump in with staff at the weekends or pre-arrange a lift.

There is good WiFi access at both beaches.

Signal can be erratic on mobile phones, best to stick to WhatsApp for calls and messages and save your data!

Costa Rica is 6 hours behind GMT (GMT -6)

In Costa Rica, American 2 pin plug sockets are used.

  • Many volunteers simply enjoy chilling out in hammocks, walking the beach, swimming, surfing, helping in the local community, getting involved at the local school and playing games at the beach with the local children.
  • There are opportunities to go surfing with a surf school right next door
  • Horse riding on the beach or in the jungle – your choice!
  • The beaches are the perfect place for relaxation and exploration as well as protecting the turtles.
  • Trips to local schools in the right season – no guarantees however as there are sporadic holiday dates and exams!
  • With the amazing wildlife on your doorstep, this project feels a long way from the hustle and bustle of life in busy San Jose.
  • There is a tree plantation project in town which is connected to the turtle organisation and volunteers are more than welcome to help and learn about native species
  • You can do local fishing trips and mangrove tours with fisherman
  • Chill out in the main office in town and make sure of the shops, cafe and bar on Sundays
  • Take plenty of books, cards and a board game, writing materials, beach games, bat and ball etc as there is a good amount of free time in between project duties.
  • Please note the ocean on this coast is strong and there are often riptides. Perfect for surfing but we recommend you don’t go deeper than waist height when standing. There are no lifeguards as this is not a tourist beach.

Most of the turtle activities take place at night time and in the mornings, so you will find that your days are mostly free for you to explore, relax and get involved with community projects. Top tips: take things with you that you enjoy doing in your free time and be proactive!

Supervision will be fairly intensive during the first few days, when you will receive a thorough induction and work-related training. Once you are comfortable with things, you might not always have a supervisor working alongside you, but there will always be staff and other volunteers around to help, and you will always be accompanied for any high risk activities.

Staff at Oyster’s head office and in-country will be responsible for your safety and welfare while you are at the project. This will start from the moment you are picked up from the airport until the time you are dropped back there. Before and after these times, you will be outside Oyster’s responsibility and should make sure that you act safely and avoid risk. This is also true if you choose to leave the project during your time off. We will give you plenty of guidance and advice about this.

Oyster has personally hand-picked some of the best volunteering projects out there. With so much amazing choice, it can be hard to make a decision. Our Animal Welfare Destination Manager, Anne, has written a guide to help you to choose the best animal volunteering project for you.
