Lanzarote is a vulcanic island and about 23% of the island’s surface was covered with lava in past. All that gray color and the apocalyptic landscape where you can see eroded rocks, craters and collapsed ground shows all the power and strength of nature as well as the powerlessness of man in front of it.

One of the most interesting galleries of connecting caves and underground grottoes in the world lies to the north of Lanzarote, at the foot of the volcano Monte de la Corona.
A volcanic tunnel is formed by the cooling and solidification of the superficial lava flow in contact with air whilst the liquid magma underneath continues flowing. The partial collapse of a section´s tunnel roof forms the structure known in Lanzarote as “Jameo” – an opening that provides access to the other grottoes. Some of the larger chambers are 9 to 12 meters high. The stone of the walls is red, orange and black, formed by compounds such as iron oxide and calcium carbonate in the stone.

Los Jameos del Agua is part of a long underground tube formed by lava after the great eruption of the Corona volcano 3000 years ago. It is part of the huge volcanic cave system of Atlantis, which also includes the largest submerged volcanic tunnel in the world. Inside the cave there is a natural lake that is connected to the sea. In 1965, César Manrique, a local artist, decided to shape the existing lava tube filled with caves and cavities created where parts of the volcanic roof collapsed.

In 1968, the island government opened the mentioned location as a series of unique entertainment venues, and the project was finally completed in 1987 with the construction of a magnificent “natural” auditorium with a capacity of 600 seats. The stairs will lead you to an unusual underground restaurant with a dance floor and a bar, and a hundred-meter-long path leads to a huge cave. The trail crosses a crystal clear, salty and tidal lagoon inhabited by a rare species of almost blind endemic albino crab named jameito. A magnificent underground auditorium emerges at the far end of the cave. Famous for its excellent acoustics, it is regularly used for concerts and performances.

Cueva de los Verdes (“green caves”) also belongs to a system of underground tunnels six kilometers long. The route, which is about two kilometers long, is open to visitors, and sightseeing takes about an hour. The lowest point to which you can descend is 50 meters and is in the form of a smaller concert hall, which also houses a piano for acoustic concerts. The cave is completely free of moisture and without stalactites and stalagmites that we are used to seeing in similar caves. In the past, local residents used underground tunnels-caves to protect themselves from pirates.
