Cocos Island 11- or 14-Day Diving Expedition

Remote Pacific liveaboard diving

Sail from Puntarenas aboard Sea Hunter to Cocos Island National Park, a UNESCO World Heritage Site far offshore. Current expeditions run 11 or 14 days on fixed dates, with a 32–36-hour ocean crossing each way.

Diver requirements

Cocos is not a beginner destination. Most dives are deeper than 18 m/60 ft, currents and visibility change quickly, and the divemaster decides who may join each dive. Bring certification valid to recreational limits; advanced skills, deep-diver training and at least 25 hours of experience are strongly recommended. The operator also says certification proof must support diving to the recreational limit, so your exact certification must be reviewed. A dive computer and evacuation-capable dive insurance are mandatory.

Life aboard

The standard 11-day expedition includes cabin accommodation, meals, snacks, non-alcoholic drinks and beer aboard, divemasters, seven diving days, 12 L tanks, weights, and air or unlimited Nitrox fills for certified divers. Rental equipment, training, transfers, park fees and specialty support cost extra or require advance reservation.

Arrive in Costa Rica at least one night before departure. Do not schedule an international flight on the day Sea Hunter returns, because ocean and port delays are possible. Adventure Inn shore nights must be booked separately unless your written package states otherwise.
