Isla de Coco National Park is found in the Pacific Ocean, in effect Costa Rica's only "overseas" territory. It lies 532 Km from Cabo Blanco on the mainland, at about 5 degrees, 32 minutes North and 87 degrees 6 minutes West.

Founded in 1978, this national park is the World's largest uninhabited tropical island. It has a terrestrial area of some 2,400 hectares and a maritime area of 97,235 hectares. Its highest point, Iglesias Mountain, reaches 634 meters and has a bit of cloud forest on top.

The island has a very broken and spectacular topography giving it many waterfalls, some of which make startling leaps directly into the sea.
