Carlsbad Caverns National Park boasts an enormous cave complex that is dramatically lit to illuminate and bring attention to the most interesting features found throughout the caverns. A self-guided path winds through the caves descending past stalactites and stalagmites ranging in all sizes, water trickling into pools, and narrow passageways opening up into rooms so large they have to be seen in person to be believed. Carlsbad Caverns is an underground wonderland that needs to be seen to be understood (and believed).
