Cocos Island is a nationally protected jungle-covered island and national park off the coast of Costa Rica. It's also a UNESCO World Heritage site.

Cocos Island is in the Eastern Tropical Pacific approximately 300 mi (480 km) southwest of Cabo Blanco, Costa Rica. A rugged and incredibly beautiful island, today Cocos Island is the most sacred National park in Costa Rica's extensive park system.

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. On the Island you will encounter a lot of pigs and not much else besides the usual vegetation.
