Dive in Cocos Island, One of the Hottest Shark Diving Destinations!

Why We Love It

Located 500 km west of Costa Rica, this lush volcanic island shelters a high number of endemic species both above and below water, as well as incredible marine life - white tip reef sharks, schooling hammerheads, dolphins, mantas - just to name a few. Because it is so remote, we think that this dive trip is a once-in-a-lifetime experience... but the truth is, many visitors go back again and again!


The dive operator works closely with the Cocos Island National Park Department in their efforts to protect the island, the University of Costa Rica's Marine department, the NGO's Turtle Island Restoration Network, Crema, and Costa Rica por Siempre.

Who Is It For?

Accomplished divers ready to indulge in one of the most well-known marine life-watching experiences. Most sites are deep and have strong currents, attracting large pelagics. Cocos Island has fantastic topography with seamounts, arches, and caves. Would you want to do anything else besides diving? If so, try the sea kayaks, snorkeling, hikes on Cocos Island. And for a real thrill, reserve a spot aboard the DeepSee Submersible and plunge hundreds of meters below the surface - a truly unforgettable experience!

Marine Life

  • The island was formed during a volcanic upheaval about two-and-a-half million years ago. It is remote, 36 hours from the mainland, and well-preserved.
  • Sometimes called the 'Little Galapagos', it is among the Top 10 dive destinations in the world: schooling hammerheads, white tip reef sharks, dolphins, mantas and marbled rays, giant moray eels, sailfish, whale sharks occasionally. Large schools of jacks and tuna, silky sharks, silver tips, marlin, creole fish, green turtles, octopuses, and the exotic rosy-lipped batfish.
  • The terrestrial life at Cocos also exhibits a high number of endemic species.
