Dive Liveaboards Costa Rica

Costa Rica liveaboards offer a gateway to the remote wonders of Cocos Island, where massive schools of hammerheads and graceful manta rays define the underwater experience.

For serious divers seeking high-seas encounters, Costa Rica is synonymous with one primary objective: the legendary Cocos Island. Because these waters lie far offshore, a liveaboard is the only practical way to access these remote sites. Most itineraries involve a significant transit from the embarkation point, typically spanning 9 to 11 days, which is necessary to reach the remote volcanic peaks and steep drop-offs characteristic of the region. Choosing a vessel in this area allows you to encounter some of the ocean's most iconic megafauna. You can expect to encounter massive schools of hammerhead sharks, Galapagos sharks, and manta rays, with occasional sightings of whale sharks. The diving experience is centered entirely on these remote offshore waters, making the liveaboard format essential for reaching the most productive sites. Regarding the fleet available, the selection caters to different preferences. You can choose between high-end yacht-style comfort, such as the Aggressor vessels, or a more rustic, functional approach like the Sea Hunter, which was originally built as a commercial diving support vessel. Regardless of the style of boat chosen, Nitrox is available on all three vessels to assist with decompression management during these long-distance expeditions. Whether you seek the refined amenities of a modern yacht or the rugged reliability of a former workboat, the focus remains strictly on the spectacular wildlife of Cocos Island.
