This Island belongs to Juan Fernandez Archipelago, which has been a passing place for explorers and sailors, hiding place for pirates and their treasures, shelter for Alexander Selkirk, the sailor who inspired Robinson Crusoe novel, and prison during the Chilean Independence War. It is actually a National Park and Unesco World Biosphere Reserve. Robinson Crusoe Island, separated from Valparaiso by 670 km of the open Pacific ocean, is not a major holiday destination. The archipelago consists of three islands with extraordinary rugged and mountainous topography, and distinctly Mediterranean climate. Rainfall varies greatly over very short distances, allowing dense rainforest with many endemic species, in contrast with other Atacama-like areas.
