Located in southeastern New Mexico, the park features more than 119 known caves formed by sulfuric acid dissolving limestone deep underground. The park’s most famous cave, Carlsbad Cavern, contains enormous underground chambers filled with stunning formations such as stalactites, stalagmites, and flowstone.
