Cocos Island... Dive in the 'Little Galapagos'

Why we love it

Located 500 km west of Costa Rica, this lush volcanic island shelters a high number of endemic species above water and incredible marine life - white tip reef sharks, schooling hammerheads, dolphins, mantas - just to name a few. Because it is so remote, we think this dive trip is once-in-a-lifetime… 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 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 with strong currents - attracting big pelagics. Cocos Island has fantastic topography with seamounts, arches and caves. Would you want to do anything else than diving?! If yes, try the sea kayaks, snorkel time, hikes on the 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.
