While it is certainly to enjoy a few of the caves at Carlsbad Caverns on your own, you will really see some amazing sights if you choose to follow one of the Ranger-guided tours. Carlsbad Caverns National Park in Carlsbad, NM has over one hundred caves and caverns, and guided tours are the best way to see the caves that might be too dangerous to explore on your own.
