Cueva del Viento ("Wind Cave") is the largest lava tube system in Europe,[1] and the sixth largest in the world, behind a series of lava tubes in Hawaii.[2] It is also considered the most complex volcanic tube in the world, due to its morphology of several levels and passages.[3]
It extends more than 17 kilometres (11 mi) and contains three different levels of passageways, each full of geomorphological phenomena such as lava pits and terraces.
Archaeological remains belonging to the Guanches, the ancient Berber native inhabitants of the Canary Islands, were found in several entries to the tube system.
At present, the Cueva del Viento is a tourist attraction of the island.
