4 Star 88x31Turtle Island leads primary research with volunteer dive research assistants at Cocos Island National Park, Costa Rica, an oasis of ocean life. Hundreds of sharks and rays, schools of fish numbering in the tens of thousands and endangered sea turtles surround the island.  Our research is setting the basis for better protections at Cocos Island and for a “Protected Swimway” to save sharks, sea turtles and other migratory animals as they swim throughout the region.

Learn how to join a Cocos Island Research Expedition today to help study, tag and track sharks and sea turtles with leading environmentalists at Cocos Island.  We are also offering a raffle for a spot on our November 2016 trip!  Learn more below and contact info@seaturtles.org for more information.
