ICOD DE LOS VINOS
Cueva del Viento is a volcanic cavity located in the district of Icod de los Vinos which bears the same name. It was formed 27,000 years ago in basaltic lavas from the first eruptive phase of the Pico Viejo volcano, next to Mount Teide (Tenerife, Canary Islands). This lava tube, the name of which (“Cave of the Wind”) comes from the powerful draughts that flow through it, is the fifth longest in the world (18 kilometres mapped to date), behind the four that are found on the largest island of the Hawaii archipelago (United States). It is a huge labyrinthine network of underground passages, with many unexplored branches that will undoubtedly add to its overall length in the future.
Cueva del Viento is also known for its unique geomorphology: its network of galleries is arranged in three superimposed levels, a phenomenon that has not been recorded in any other place in the world. It also has a wide variety of structures of primary origin such as lava stalactites, lava cascades, side terraces and lava lakes, among others, as well as concretions of varying composition (calcium carbonate and other salts).
