Schooling hammerheads, countless white-tip sharks, mantas, tuna and even whale sharks call Cocos home.

Escape to Cocos Island on a liveaboard scuba diving trip in Costa Rica! Cocos is a lush, green uninhabited island resting 342 miles off Costa Rica's Pacific coast. Rocky pinnacles surrounding Cocos are beacons for big animals and big action. Schooling hammerheads, countless white-tip sharks, mantas, tuna and even whale sharks call Cocos home.

Cocos Island National Park was designated a World Heritage site by UNESCO in 1997. Weather permitting, OKEANOS AGGRESSOR I® guests are shuttled ashore to hike through the jungles of Cocos and swim in her many waterfalls. All ten-day trips offer seven days of Costa Rica liveaboard scuba diving.

The Okeanos Aggressor I® & Okeanos Aggressor II® depart from Puntarenas, Costa Rica. Boarding and departure depends on the tide schedule. Immediately after boarding the liveaboard yacht departs for its 36 hour crossing to Cocos Island. There are multiple dives throughout the day for an average of 24 dives on 10 night charters. No night diving is currently offered at Cocos Island.

Water temperatures range from 72 - 82F, 22 - 28C with cooler thermoclines. 3 - 5 mm wetsuit recommended

The Okeanos Aggressor I & II are each equipped with two 8" x 22" tenders.  All dives from tenders.
