2021 Lanzarote, Jameos del Agua - Subterranean salt lake

The aboriginal word jameo refers to a large opening in a lava tube, which is formed when parts of the roof collapse. Both Jameos del Agua and Cueva de los Verdes are located inside the volcanic tube, created by the eruption of the Monte Corona volcano. The tube is 6 km long, of which at least 1.5 km is located below sea surface, and is therefore called “Tunnel of Atlantis”. Situated in the tunnel’s closest section to the coast, Jameos del Agua comprises at least three holes or caves, namely:
Jameo Chico (which gives access to the inside part)
Jameo Grande
Jameo la Cazuela
