Marine Conservation & Underwater Adventures | Costa Rica

Passionate about Marine Conservation? Take a trip to Costa Rica and get involved with some of the fantastic work organisations do. Enjoy some underwater adventures while you’re at it!

The craggy Osa Peninsula sits in the remote southern reaches of Costa Rica’s Pacific coast. Jutting out to sea a strip of lush rainforest borders powdery sands. Home to leatherback, hawksbill, green and olive ridley sea turtles, thousands head up the beach between the months of March and October to hatch their eggs.

Rise early and help local specialists on the Osa Marine Conservation project working to increase sea turtle populations.

Hop aboard a research vessel and join marine biologists in their efforts to tag and track hammerhead sharks. Collect scientific data on shark fisheries and help to identify and describe critical habitats of hammerhead sharks.

On an accompanying skiff that doubles as an open water research lab fish, catch, measure, tag and then document the vital shark data.


Back on land, choose to adopt and name a shark, receiving data and reports of its travels and growth over its lifespan. You will be helping protect the Golfo Dulce, the first sanctuary for hammerhead sharks in the world.

Begin the expedition on Argo, a singular dive expedition cruiser. A blend of work ship and luxury yacht, Argo accommodates up to 18 guests and is mothership to the DeepSee submersible.

Once onboard the DeepSee, a custom-built one-atmosphere submarine, plunge to depths of 1,500 feet (450 metres). Sitting in the orb of the cockpit, take in 360-degree views of your surroundings and forget that you’re behind glass.

Explore Guanacaste where the wild and remote Bat Islands are found. Home to a dozen large bull sharks, there are schools of thousands of kaleidoscopic fish. Watch in awe as pelagic fish, sailfish, manta rays, and whale sharks cruise by the orb.

Discover the Golfo Dulce, a tropical fjord home to a diverse ecosystem including marine mammals, reptiles, sharks, and invertebrates including coral reefs.

Another route takes travellers to Cocos Island, part of the beautiful Osa Peninsula. Known to be home to 2.5% of the world’s biodiversity, it is Costa Rica’s destination for nature lovers and adventurers.
