Visitors to Carlsbad Caverns can walk through a natural entrance or take an elevator that descends 754 feet underground beneath the Chihuahuan Desert into a labyrinth of more than 119 caves hidden beneath the surface. The Big Room is a large limestone chamber which is almost 4,000 ft long, 625 ft wide, and 255 ft high at its highest point and is the largest chamber in North America and the 32nd largest in the world.
