Lava Tunnels
Santa Cruz Island, Galapagos
The lava tunnels on Santa Cruz were formed as the outer skin of molten lava solidified but the liquid magma inside continued flowing, leaving behind a series of empty tubes. Visitors can walk through these underground channels, often more than a kilometer in length, and may have the opportunity to glimpse barn owls here.
