10 or 12 day Cocos Island diving adventure

Located in the Eastern Tropical Pacific, 300 miles southwest of Cabo Blanco, Costa Rica, lies the renowned Cocos Island Marine Park. A rugged yet incredibly verdant island, this World Heritage Site is the spectacularly beautiful crown jewel of Costa Rica's many National Parks. In 1994 after several return visits to the island, Jacque Cousteau pronounced Cocos, "The most beautiful island in the world."

Among Cocos Island's many attributes is a startling degree of biodiversity. This Island's world-renowned waters explode with life, including innumerable white tip reef sharks, schooling hammerhead sharks, dolphins, mantas and marbled rays, giant moray eels, sailfish, and of course the occasional whale shark. Other common encounters are large schools of jacks and tuna, silky sharks, silver tip sharks, marlin, Creole fish, green turtles and octopus.
