Natural and Archaeological Wonders

This collection highlights the volcanic geology and traditional hydrological systems of Tenerife. It features the Cueva del Hielo, a high-altitude lava tube known for permanent ice deposits, and the Cuevas Negras, which served as significant archaeological sites for the indigenous Guanche people. The list also documents numerous 'galerías'—specialized horizontal tunnels used for groundwater extraction—and natural springs like Fuente de Chavao, illustrating the island's historical reliance on subterranean water sources.
