The Big Room

Carlsbad Caverns National Park is a national park in the Guadalupe Mountains of southeastern New Mexico. The primary attraction of the park is the show cave Carlsbad Cavern. Visitors to the cave can hike in on their own via the natural entrance or take an elevator from the visitor center. The park has a large limestone chamber, named the Big Room, which is almost 4,000 ft long, 625 ft wide, and 255 ft high at its highest point. The Big Room is the largest chamber in North America and the 32nd largest in the world. The park also has a Natural Entrance Trail, which is extremely steep and not recommended for visitors with heart or respiratory conditions. Parts of the Big Room Trail are wheelchair accessible
