This is the natural entrance to Carlsbad Caverns National Park is in the Chihuahuan Desert of southern New Mexico (you can also take an elevator directly down...not the same if you ask me!!) 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. Such an amazing natural wonder!
