Carlsbad Caverns National Park is in the Guadalupe Mountains of southeastern New Mexico. The primary attraction of the park is the show cave, Carlsbad Cavern. Visitors to the cave can hike in on their own via the natural entrance or take an elevator from the visitor center.
Carlsbad Cavern includes a large limestone chamber, named simply the Big Room, which is almost 4,000 feet (1,220 m) long, 625 feet (191 m) wide, and 255 feet (78 m) high at its highest point. The Big Room is the largest chamber in North America and the thirty-first largest in the world. Approximately two thirds of the park has been set aside as a wilderness area, helping to ensure no future changes will be made to the habitat.
