Best Time to Dive in Cocos Island

The island is best known for spectacular shark-spotting opportunities, so between April and November, watch out for schools of scalloped hammerheads as they cut through the water. Outside of these months, keep your eyes peeled for bull, silky, white-tip, Galapagos and silvertip sharks, with even the occasional sighting of an elusive whale shark.

If sharks aren't your thing, don't worry - there's plenty of other fish in the sea (quite literally). As you dive down, expect to spot elegant eagle and manta rays weaving their way through the water.

Located over 500 miles from Costa Rica's western coast, Cocos Island is only accessible via liveaboard. This distance from mainland Costa Rica has meant that Cocos Island has become one of the world's finest liveaboard destinations, with a number of vessels offering ten-night itineraries all year round.
