Liveaboard Scuba Diving Cocos Island Costa Rica

Located in the Eastern Tropical Pacific, 300 miles southwest of Cabo Blanco, Costa Rica, lies the famous Cocos Island Marine Park. A rugged and incredibly beautiful island, this World Heritage Site is the crown jewel of Costa Rica´s many National Parks. Cocos Island has an irregular coastline, which makes estimation of land area more a matter of opinion than a surveyor’s science, but it is roughly five miles by two miles (8 x 3 kilometers).

The island was formed during a volcanic upheaval about two-and-a-half million years ago and is composed of basaltic rock, labacorite and andecite lava flows. Its landmass is punctuated by four mountain peaks, the highest of which is Cerro Yglesisas, at 2,080 feet or 634 meters.

The island has two large bays with safe anchorages and sandy beaches: Chatham is located on the northeast side and Wafer Bay is on the northwest. Just off Cocos are a series of smaller basaltic rocks and islets. The largest satellite is Isla Manuelita (formerly Nuez).
