The Tunnel of Atlantis in the Canary Islands stretches 5,000 feet underwater, and contains a whole entertainment complex, as well as albino crabs. The lava tube was created 20,000 years ago during a volcanic eruption, leaving behind caverns formed from the molten lava.

In the 1960s, artist and architect César Manrique turned a portion of the tunnel into Los Jameos del Agua, a complex with a pool, restaurant, bar, a 600-seat concert hall, and cafe. It’s all accessed from a staircase that descends into the jameos, geological features that occur when part of a lava tube collapses and opens to the sky.

Down in the caverns are stunning stalactites, stalagmites, and water systems, as well as a unique species of blind albino crabs that lives in the ponds. Guests can watch them skitter around while on their way to a volcanic-set drink or lava tube swim.
