Carlsbad Caverns National Park
Okay, you may think you’ve seen caves, but nothing will prepare you for the ultimate cave experience.

The underground world at Carlsbad Caverns National Park is trip through an gi-normous underground cathedral that Mother Nature has painstakingly carved out over millions of years.

And talk about big, the caverns are volumous enough to swallow 14 Astrodomes. The “Big Room” Cavern alone covers 600,000 square feet, making it the largest underground rock formation in the Western Hemisphere.

The circular trail through all of the Big Room’s richly decorated features is 1.5 miles and takes about 2 hours by foot. The enormity of it all will make your jaw drop.
