'Carlsbad Caverns National Park' is an American national park 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.
The park entrance is located on US Highway 62/180, approximately 18 miles (29 km) southwest of Carlsbad, New Mexico. Carlsbad Caverns National Park participates in the Junior Ranger Program. 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 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 fifth largest chamber in North America and the twenty-eighth largest in the world.
