Delve 750 feet underground with this self-guided walking tour of the unbelievably vast Carlsbad Caverns. Marvel at the enormous echoing spaces of the aptly named Big Room. Immerse yourself in a strange new world in the cave system’s Twilight Zone. Learn how the weird and fascinating rock formations actually form. As you stroll along the Natural Entrance Trail and Big Room Trail, you’ll also hear about the story of Jim White, perhaps the first explorer of these caves over a century ago.

After booking, you can check your email before downloading the Action Tour Guide app, enter your unique password, and access your tour. The preceding steps require good internet/wifi access. Follow the audio instructions and the route from there.
