Carlsbad Caverns is a must-see for any caving enthusiast, known for its expansive system of 119 caves. Located in southern New Mexico, this UNESCO World Heritage site is home to the famous Big Room, which measures 4,000 feet long, 625 feet wide, and 255 feet high—one of the largest underground chambers in North America.
Visitors can enjoy guided tours or explore independently through stunning formations like stalactites and stalagmites. A highlight? The Bat Flight Program, where thousands of bats take flight at dusk, creating a mesmerizing spectacle.
