Cocos Island fully justifies its place as one of the world's finest liveaboard destinations. This remote Pacific outpost is a magnet for sharks, most notably large schools of hammerheads.

Located over 500 kilometres off the western coast of Costa Rica, the only way to dive Cocos Island is by liveaboard. A number of vessels offer ten-night itineraries throughout the year. From April to November, these waters are famous for encounters with vast schools of scalloped hammerheads. November to April brings calmer weather conditions and more excellent marine life encounters.

In addition to hammerheads, divers may encounter bull, silky, silvertip, Galapagos and white-tip sharks. Eagle and manta rays are also frequent visitors, along with occasional whale sharks.

The itinerary below is based on a ten-night trip on board the Okeanos Aggressor II.
