The Project

The Osa Peninsula

The Osa Peninsula is one of the most intensely biodiverse places on the planet and contains 2.5% of the world’s species crammed into an area the size of New York City! The Corcovado National Park, which takes up a third of the peninsula, is the crown jewel in Costa Rica’s park system and is home to more than 500 species of trees, 140 species of mammals, 370 species of birds, 40 species of freshwater fish, 120 amphibians and reptiles, more than 150 species of orchids and more than 6000 species of insect and butterfly. The waters around the peninsula are home to over 25 dolphin and whale species, all four species of Pacific sea turtles, sharks, manta rays, tuna, blue marlin and sailfish – to name but a few – and the Caño Island marine reserve in Drake Bay is a globally important mating area for humpback whales from both the northern and southern hemispheres!

The Programme

The programme has been working with local communities to protect sea turtles in the Osa Peninsula for 11 years, and is based at the Río Oro National Wildlife Refuge - the most important nesting beach on the South Pacific coast of Costa Rica.

When to Come

Volunteers are needed at Río Oro Beach from the beginning of July to the end of December for 1 to 12 weeks in duration, every year.

Río Oro Beach

The programme’s site at Río Oro beach offers volunteers the chance to protect one of the most important nesting habitats on the Pacific coast of Costa Rica. The beach receives over 4000 Olive Ridley and Green sea turtles each year, and the area is a pristine and remote wilderness paradise! Volunteers are practically guaranteed to see turtles nesting, and often they will see dozens during their stay.

The Río Oro site is located on the unsealed road between Puerto Jiménez and Carate (the nearest village), where the road terminates just a few kilometres from the La Leona ranger station and southernmost entrance to the Corcovado National Park. Carate itself has another sea turtle project that protects Carate beach. Volunteers from both projects have the chance to collaborate with conservation activities and spend free time together, and there are often a large number of volunteers working in the area.

Weighing eggs at the turtle hatchery


As a volunteer, you will be working under the direct supervision of a Scientific Supervisor throughout your time at the programme. Activities include:

  • Performing night surveys on the beach to find nesting turtles and help protect them from illegal extraction and predators (4-6h per day).
  • Relocating eggs, building new nests.
  • Monitoring nests and baby turtles. 
  • Tagging female turtles.
  • Collecting biometric data on the beach.
  • Releasing baby turtles into the ocean.
  • Nest excavation (exhumations)
  • Maintenance of beach and camp.
  • Helping with local environmental education and ecotourism projects.

Food, Lodging, Travel

Facilities at the main camp

Food & Accommodation

Accommodation is at the Hacienda Río Oro eco-lodge near to Puerto Jiménez in the Osa Peninsula. Volunteers stay in mixed dorms with private bathrooms in a luxurious new tented camp at the site and accommodation includes three meals per day. The camp also has several communal areas with hammocks, football, volleyball, ping-pong and hand-wash laundry facilities. There is no ‘grid’ electricity however, the Hacienda Río Oro is equipped with solar panels and generators that provide lighting and power at night, and there is cell phone and Wi-Fi internet service available for essential communications.

Dorms at Rio OroIt is important to be aware that there is no village nearby, although there is a small bar within walking distance and weekly social events are organised with the volunteers from the neighbouring turtle projects at Piro and Carate. Volunteers are also free to visit the town of Puerto Jiménez on their days off and as part of planned excursions. Puerto Jiménez is the largest and most developed town in the Osa Peninsula and has banks with ATM machines, supermarkets, bars, restaurants, souvenir shops, a post office, an airport and a number of other amenities. There is a local ‘colectivo’ truck that travels from Puerto Jiménez to Río Oro twice daily and costs $6 each way (2.5 hours). There is no ATM in Drake Bay, however the hostel accepts credit and debit cards in order to pay for any tours.

Working Conditions & Requirements

All volunteers should be at least 18 yrs old age. English is required and Spanish is very helpful, even if basic, but a small amount of Spanish would go a long way. A strong interest in conservation is required, as is good team work spirit and flexibility. You should also be in good health and fit - you need to be able to work 2-3 nights per week (rest the next day) and walk several kilometres on soft sand - please note that the nesting beach is a 6kms walk from the Ecolodge, although you are taken there by car, but you will be doing lots of walking for turtle patrols. The work at the project can be extremely tough and is not necessarily for everybody. Weather conditions can be extreme, especially since the nesting season coincides with the rainy season, with heavy rainfall and storms often a daily occurrence (rainy season = turtle season!). The majority of the work is nocturnal and it will be necessary to adjust to sleeping in the daytime, often enduring high temperatures and humidity. The way of life is rustic, but the environment is full of jaw-dropping natural beauty and extraordinary biodiversity. After a little time at the project you will no doubt find yourself adjusting to the life of a local.

Tours and Free Time
We know that volunteers come not only to work but also to discover the incredible nature of the Osa Peninsula, and the programme offers unforgettable tours and activities at two different sites. The Hacienda Río Oro offers horse riding and kayaking and several farm activities, such as cheese making, and volunteers are free to trek around the trails surrounding the site.  

You can also visit the village of El Progreso, Drake Bay, and stay at the Drake Bay backpackers which offers all of the most popular tours in the area, including trekking in the Corcovado National Park and snorkeling or diving at the Caño Island marine reserve. All volunteers may choose to spend some time at Drake Bay Backpackers, and it is highly recommended that you plan to depart the programme from Drake Bay so that you can take advantage of the hostel, relax and enjoy some tours during your last few days. Long-term volunteers may choose to stay at Drake Bay Backpackers on several occasions during their placement. Accommodation at the hostel is in mixed dorms and includes three meals per day. The site is equipped with free Wi-Fi, hot showers, volleyball, a swimmable river and trail, yoga, cinema screen and several chill-out areas with hammocks and sofas.

Volunteers having lunch at Rio OroHow to get there?
Multiple airlines fly to San José, Costa Rica, via the United States, including United, American Airlines and Delta. From Europe, British Airways, Iberia and Condor all fly to San José either directly or with a short stopover in the Dominican Rebublic. Please remember not to look for San Jose in California, it is San José International Airport (Juan Santamaria) - code SJO.

It is highly recommended that volunteers plan to arrive via Puerto Jiménez (near to the Hacienda Río Oro), and leave via Drake Bay from Drake Bay Backpackers.

Arrival information to Puerto Jiménez - By bus 8 hours and by plane ($15), 40 minutes ($90 to $150). You can book online at: http://www.natureair.com or http://www.flysansa.com.  Departure Information from Drake Bay - by bus and boat duration is 8 hours ($21 plus $35-40) and by plane duration is 40 minutes ($90 to $150).  From Drake Bay airport, there are several daily departures to San José with Nature Air and Sansa. The hostel provides a free shuttle service to the airport, which is located in the same village of El Progreso.

Volunteer Testimonials

Andy White from the UK volunteered for 10 weeks from October 2016 to January 2017: 

Pacific Sea Turtle projectVolunteering with the Pacific Sea Turtle Program was a truly memorable and life-changing experience. Having the opportunity to work closely with such amazing, prehistoric creatures was unlike anything I'd ever done before and something I would recommend to anyone with an interest in animals, conservation or the natural world in general.

While challenging at times, particularly during the torrential downpours at the start of my ten-week volunteer period, each day provided an exciting new adventure. The comradery between the international mix of volunteers was really positive, with everyone pulling together and having a blast while doing so. I made many new friends while on the project and getting to know people from such a variety of different cultures was eye-opening and thoroughly enjoyable.

Pacific Sea Turtle project

The Pacific Sea Turtle Program provided the perfect platform for me to develop numerous interpersonal and professional skill, particularly as I was given the opportunity to take on a leadership role, passing on what I had learned to new volunteers and heading up night patrols and morning censuses.

As someone who has always been passionate about nature, being in such a beautiful, wild location with a group of inspiring and dedicated individuals was unforgettable. Magical census sunrises, babysitting hatchlings as they set out on their incredible journey, the mesmerizing dance of a nesting Olive Ridley and turtle tagging during midnight patrols under a sky full of stars are just a handful of the memories that will live with me forever.

I feel honored and privileged to have been able to support the Sea Turtle Program and would unreservedly recommend it to anyone with an interest in conservation!

Previous volunteer Laura Hickey, from the USA describes her time at the project:

Coming to Costa Rica and volunteering was a spur of the moment decision of mine. If I could go back to that moment, the only change I would make would be planning to extend my stay. One week here, while wonderful, surely wasn´t enough for my liking. From the moment I met two other volunteers in our travels to the Hacienda, I felt welcome and excited.

Landing in Puerto Jimenez, we were greeted by departing volunteers and a wonderful staff. When I did some research about the program prior, I felt very prepared for the workload and program.

Volunteers on the beach in Costa Rica

An unexpected surprise, however, was the family-like atmosphere. Each meal, day,and patrol is shared with others from many different areas of the world, contributing their own personalities and cultures. Of course, I also learned a lot about turtles in my stay here. The nesting process, identification, and general activity of sea turtles was very unexpected and beautiful to be able to witness. You feel a connection with the turtles as you record and possibly relocate their nests.  I felt like another parent in the situation. Along with turtles, Costa Rica and the Hacienda have much more wildlife to see and learn about including a variety of reptiles, birds, and small mammals. Overall, I only have great things to say about Rio Oro, the staff, and of course the turtles. I could only wish for more time here.


Volunteers in Costa Rica

Previous volunteer Daniel Ridley from Scotland describes his time at the project:

I thoroughly enjoyed my two weeks at Rio Oro working, socialising and patrolling the beach. The research assistants (Ed, Emily, Eva and Alberto) and head of the project, Aida, have made my stay very comfortable and great fun. They are extremely friendly and although their primary job is turtle conservation they are always making sure you are enjoying yourself and are happy with the activities and the general day to day goings on. The people I have stayed with here have all been very welcoming and some of the most interesting and diverse people I have met. Patrolling and seeing turtles has got to be the highlight of the trip but learning about the local area, working to help the project, exploring the surrounding area and hanging out with the other volunteers don´t fall too far behind. It has been an experience of a lifetime here at Rio Oro and I wish my writing skills were good enough to convey my appreciation of my time here. I will never forget the people and the wildlife and I hope I can return soon.

Volunteers Swimming in Costa RicaPrevious volunteer Mackenzie describes her time at the project:

I came to the project as an environmental science major trying to figure out if the path of a field researcher is one I really want to take. This was the best possible decision I could have made. During night patrol the last 4 weeks I worked on over 20 turtles, helping to measure the turtles' carapace, write down data, camouflage nests, and relocate eggs that are at risk. While the turtles are obviously the main purpose of being here, we have ample free time during the day to go to the beach or the river, travel to Puerto Jimenez, go on hikes, hit up the bar, and relax in hammocks.

Pacific sea turtle in Costa Rica The Osa Peninsula is absolutely beautiful and the wildlife you will see is incredible. In addition to all of this, the volunteers and leaders here are some of the most wonderful people you will ever have the pleasure to meet. Thank you Emily, Ed, Eva, Alberto, and Aida for making this such an unforgettable experience and I'll miss you all! I may be leaving with more bug bites than the entire population to Costa Rica has put together and a recently developed fear of rice and beans, but I can't say enough good things about this program. Thank you again and I can't wait to tell everyone back in California about my time at Hacienda Rio Oro.

Sea turtle volunteers in Costa RicaPrevious volunteer Linda describes her time at the project:

The time I spent at Rio Oro was an unforgettable experience. I really enjoyed how remote it was, the rest of the world just seems really far away. All the people were great and because you spend all your time together you become good friends very quickly. I saw turtles almost every night and the work is so fascinating. I think the best part was being on the beach, you look around and as far as you can see, there is no other person, With all the work being at night, you very quickly get used to sleeping at any hour, but it also means you have the days off for tours or activities, or to just chill in a hammock all day. I would definitely recommend coming here and I will never forget the time I spent here.
