Carlsbad Caverns National Park is located in the Chihuahuan Desert of southern New Mexico. It features more than 100 caves. The Natural Entrance is a path into the namesake Carlsbad Cavern. Stalactites cling to the roof of the Big Room, a huge underground chamber in the cavern. Walnut Canyon Desert Loop is a drive with desert views. Rattlesnake Springs, a desert wetland, attracts reptiles and hundreds of bird species. In addition to the rare sights of the caverns, it's also possible to watch hundreds of thousands of Brazilian Free Tailed Bats fly out of their cave at sunset every day. There is a great amphitheater for visitors to sit in front of the cave and watch, hear and smell the bats as they take flight. The cave is also the entrance where a well planned trail provides access to the caverns.
