Place to see: Carlsbad Caverns, Carlsbad, New Mexico, United States

About this place:

Carlsbad Caverns National Park is an amazing United States National Park located in the Guadalupe Mountains in southeastern New Mexico. The park contains 113 caves, including some of the largest in North American, which were formed when sulfuric acid dissolved the surrounding limestone rock.

Visitors can hike into the interior caverns on their own through the cave's natural entrance, or take an elevator directly down into the center of the public cave area. For the more adventuresome traveler, take a guided tour of some of Carlsbad's less traveled caves. Helmets and head lamps are a must for this tour since you'll be exploring smaller caves off the paved paths of the public areas.
