Osa Conservation Volunteer Opportunity


About Us

Osa Conservation, a non-profit organization, is devoted to protecting the natural diversity of the Osa Peninsula in Costa Rica. The organization aims to conserve and preserve the terrestrial and marine biodiversity by creating projects protecting the ecosystem, enhancing scientific understanding, providing education and training, and providing sustainable economic opportunities.

Join us and experience “where the rainforest meets the sea.” Acclaimed as the most biologically intense place on earth by National Geographic, the Osa Peninsula reigns as the crown jewel of Costa Rica. In the enchanting south Pacific region, the Osa encompasses 2.5% of the earth’s biodiversity, including over 300 endemic species of plants and vertebrates, over 400 species of birds, and 140 types of mammals. Osa Conservation seeks energetic and engaging volunteers who are passionate about protecting the earth’s wild tropical regions of rainforests, wetlands and beaches.

Accommodations: Conservation Volunteers stay at Osa Conservation’s biological station. Accommodations include a bunk bed with mosquito netting, clean sheets and a bath towel, 3 meals a day centered around local Costa Rican cuisine, and refreshing cold water showers (which are appreciated most days in the heat).

Requirements: To volunteer, we ask that you commit to a 2-week minimum stay to account for the 2-day training period, but you can stay for as long as you would like!

If you are interested in staying for 6 months or more, you may be eligible to apply for our Research Field Assistant positions that are offered for more specific opportunities.

If you are visiting for less than 2 weeks, we would love to have you join us as a Conservation Visitor (and you still get to see and do much of what is listed here!)
