Lava Tunnels

Santa Cruz Island

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.
