Carlsbad Caverns National Park is a popular attraction in New Mexico. Containing the Carlsbad Cavern, also known as the 'Big Cave', one of the largest underground chambers on earth. A UNESCO World Heritage Site, the cave is one of 80 around the park, but is incredibly popular for tours due to its stunning stalagmite and stalactite formations.
Visitors enter the cave by descending over 600 feet (183m) in an elevator, and explore the chambers via paved trails that are mostly wheelchair accessible. There is also a natural entrance by the visitor centre, involving a longer and rougher walk.
