EXPEDITION
Join us on an Offshore Expedition to one of the hottest spots in the world for pelagic diving. Cocos Island is 550km off the shore from Costa Rica and one of the few remote islands in deep Eastern Pacific. Like Galapagos it's a magnet for pelagic life - famous for its massive schools of hammerheads. You can also expect to dive with silky sharks, Galapagos sharks, as well as big sharks like whalesharks and tiger sharks. Amongst the regular visitors are also dolphins, pelagic manta rays, turtles and sometimes even Orcas or whales. It's all possible, in Cocos!!

THE ITINERARY
Cocos Island Marine Park is 550km off the coast of Costa Rica. We fly to San Jose and will drive from there for 3h to Golfito, from where we depart. Its a long trip out to the island which can take 30-40h. It is a remote island in the middle of deep ocean, and your excitement will grow with every mile.
THE DIVING
Cocos Island Marine Park is situated in the middle of deep, deep water. Pelagic animals take a break from their journeys here and relax, clean or feed off the steep drop-offs.
We are going to be going to diving in the wettest season of the year. As you can expect from an Insider divers Expedition there is a reason - because this is also when you can expect the most action. It's smack in the middle of the best time for the really massive schools of hammerheads and eagle rays. Sometimes the biggest whalesharks, the pregnant 12-15m ones pass by here on their migration to their birthing grounds.
The diving in Cocos is advanced. You can expect strong currents, choppy to rough seas, and big animals. You should be comfortable in the water, have at least 80 dives under your belt, and preferably been on at least one liveaboard before.
