Costa Rica : Sea turtle protection

Sea turtles have become synonymous with protecting our oceans. Watching these amazing sea creatures lay their eggs on the beaches is an immersive experience. It is indescribable to see these huge creatures in real life and to contribute to their protection. As an Eco Volunteer in this conservation project, you will help protect sea turtles on the Pacific Coast of Costa Rica.  

A 500-hectare marine and land reserve

The project in Costa Rica was founded over 30 years ago and works hard to protect the the sensitive ecosystem and breeding grounds of sea turtlesThe project site includes an area of over 500 hectares made up of marine and land reserve. The dreamlike landscape is characterized by small bays, beautiful beaches, mangrove forests and countless small islands.

Olive Ridley, Leatherback and Green turtles

The volunteer mission takes place at the "arribadas" site. Arribadas are the massive, synchronized nesting of the olive ridley turtle. It's a fascinating natural phenomenon that only happens a few times a year. In fact, during the high season, from around August to January, an average of 200,000 turtles come to the beaches, making this region the second largest sea turtle breeding site in the world. In addition to the Olive Ridley turtle, two other turtle species nest here: the Leatherback turtle and the Green turtle.

The role of the eco-volunteer with sea turtles

To support sea turtles, volunteers carry out exciting night-time patrols along Pacific beaches. Their role is to spot sea turtles, observe their behavior and make sure their nests are protected. These night patrols are always carried out in teams with other volunteers and/or local staff. Sea turtles only come to the beaches after dark, between 6pm and 6am. Although sea turtles come to the beaches of this reserve all year round, the peak season is between August and January.

Protecting turtle eggs

To protect sea turtle eggs from natural and human predators (turtle eggs are marketed as delicacies), and to ensure the growth of the turtle population in the Pacific, volunteers collect certain eggs. These eggs are kept in incubators until the baby turtles hatch after around 45 to 60 days. After successful reproduction, the baby turtles are released back into the wild.
In addition to night patrols, volunteers take part in beach clean-ups during the day, collecting garbage to keep sea turtle breeding sites clean.

  • The tasks entrusted to ecovolunteers can vary. They depend on various factors such as the number of volunteers, the weather, the season, the current needs of the project, as well as motivation... Not all volunteers can be fully involved in all these tasks.
