You can choose between 2 programs
  • Osa In-Water Volunteering
  • Pacuare Volunteering



Osa In-Water Volunteering Program

The project Osa In-Water is located on Playa Blanca, close to Puerto Jiménez on the Osa Peninsula in the southern Pacific province of Puntarenas, Costa Rica. The surrounding landscape of Playa Blanca is a lot of flat farmland, however most of the Osa Peninsula is under some kind of protection. The reason why is because this area is one of 25 biodiversity hotspots worldwide, with a vast variety of mammals, birds, amphibians, reptiles and insects.

How can you help?

The project recruits national and international volunteers to support our field work as part of the research and conservation project. It is essential that the monitoring and tagging efforts continue for a better understanding of the presence of different size classes of these species, as well as the role of the animals in the reef, and the use given to the different habitats studied and their health status. Volunteers support our scientists and research assistants in the field work, where tasks include the support in our four working areas:

  • In-Water Monitoring
  • Rescue and Rehabilitation Center
  • Mangrove Reforestation Program
  • Sea Grass Monitoring


We supply Accomodations and Food.

Pacuare Volunteering Program

The project is located in the north of the Caribbean province Limón, 1km northwards of the Pacuare River Mouth. The beach is part of the 50km coastline stretching between Tortuguero National Park and the port of Limón, one of the biggest ports of Costa Rica. It is an important nesting beach for Leatherback and Green Sea Turtles and sometimes also visited by the rare Hawksbill Sea Turtle. Moreover the tropical rainforest, mangroves and rivers are home for a lot of exotic animals like monkeys, sloths, crocodiles and a numerous variety of birds and insects. Surrounded by this lush and beautiful nature, you will find the community-based volunteer project of LAST.
