Cueva de Los Verdes Cave
Cueva de Los Verdes is one of the largest volcanic caves in the world located on the island of Lanzarote in the Canary Islands archipelago. This cave was formed five millennia ago by the eruption of the Corona volcano. During the eruption, a stream of liquid lava burned an oblong depression in the island’s rocks. While the lava below was still very liquid and fluid, its outer layers gradually solidified, resulting in the formation of a peculiar 6.1 kilometer-long tube. When the liquid lava flowed out of this pipe, what remained was a beautiful natural monument called Cueva de los Verdes.
