Carlsbad Caverns National Park is a United States National Park in the Guadalupe Mountains in southeastern New Mexico. The primary attraction of the park for most visitors is the show cave, Carlsbad Caverns. Visitors to the cave can hike in on their own via the natural entrance, or take the elevator (the exit for everyone) directly to the Underground Lunchroom some 750 feet (230 m) below.

The park has two entries on the National Register of Historic Places: The Caverns Historic District and the Rattlesnake Springs Historic District. 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.

Carlsbad Caverns includes a large cave chamber, the Big Room, a natural limestone chamber which is almost 4,000 feet (about 1,219 m) long, 625 feet (190.5 m) wide, and 350 feet (about 107 m) high at the highest point. It is the third largest chamber in North America and the seventh largest in the world.
