Cocos Island Expedition 2026 - Hammerhead Sharks

The expedition

The wildest
sanctuary
in the Pacific.

Cocos Island is one of the last pelagic paradises on the planet. A UNESCO World Heritage site, 550 km off the coast of Costa Rica, with no tourism, no neighboring islands, only deep ocean and one of the largest concentrations of sharks in the world.

Schools of hammerhead sharks, Galápagos sharks, whitetip sharks, manta rays, giant tuna and dolphins accompany nearly every dive on the volcanic pinnacles that rise from the depths.

Dive For Fun boards the Sea Hunter, a world reference in liveaboards for Cocos, for 10 nights of sailing, 21 dives and an experience that few divers in the world have ever lived.
