The Cave of Los Verdes

The Cueva de los Verdes or Green Caves is part of the Atlantida underground Cave system formed some 3000 years ago during the eruptions of Monte Corona.The original inhabitants, the Guanches, used to shelter here from Pirates that once tormented the island.The tunnel is over 6 km long with an additional 1.6 km under the sea and is the longest Volcanic Tunnel in the World (the underwater section has not been fully explored), although only about 2 km are open to the public.The cave measures more than 15 meters wide and 15 m high.The lowest part of the cave is used occasionally as a concert hall.
