Liveaboard diving in Costa Rica is centered around the remote paradise of Cocos Island where hammerhead sharks are common and Caño Island where you might also see mantas, whales and dolphins.
The water around Costa Rica is fantastic for diving, with the very best liveaboard diving centred around the remote islands of Cocos, Caño, Bat and Guanacaste. Here you’ll find lots of pelagic species. Cocos Island is great for hammerhead shark encounters, while you’re likely to see mantas at Caño Island and bull sharks at Bat Island. Furthermore, both islands are uninhabited, so diving in these areas is only possible from a diving liveaboard. Due to the distance from the mainland, diving safaris to Cocos and Caño have an itinerary of around 8 to 10 days. Finally, the best time to dive Caño Island is from January to June, while the best time to dive at Cocos Island is from June to December.
