“experience a stunning limestone cave”

Experience a stunning limestone cave in Southeastern Arizona that boasts world-class features. This “live” cave, discovered in 1974, is host to a wide variety of unique minerals and formations. Water percolates from the surface and calcite formations continue to grow, including stalactites dripping down like icicles and giant stalagmites reaching up from the ground. Tour guides will unveil this fascinating underground landscape during a memorable 1½ hour tour.The Discovery Center features museums exhibits, a large gift shop, regional displays, theater, and educational information about the caverns and the surrounding landscape. There are also campgrounds, hiking trails, lockers, shaded picnic areas, a deli, an amphitheater, and a hummingbird garden.

Fabulous active caves. Leave your sweater in the car as caves are warm and humid.

Unbelievable! You can look at pictures all you want...there’s nothing like being there. You can’t take in purses, cell phones etc. they do have lockers that need 4 quarters. If you wear a coat and get too warm they ask you to roll it before tying to your waist to prevent flapping...it causes lint to get in the air and attach to the walls. Our guide Wilson was wonderful with a dead pan delivery that was funny as well as informative.

Kartchner Caverns is particularly unique because of the magnitude of its physical features. The caverns are home to the first cave occurrence of a “birdsnest” needle quartz formation, and the first reported occurrence of “turnip” shields.

Additionally, the cavern has the tallest and biggest column mass (a 58 footer named Kubla Khan), one of earth’s longest soda straw stalactites, one of the most extensive formations of brushite moonmilk, and other varieties of cave formations that are uncommon. Plus, the cave is living, which means many of its formations are still growing and changing!

This park is one that campers adore as well. There are spaces for RVs, tents, and even cabins here. Campers love this place, in part because Kartchner Caverns is a designated International Dark Sky Park, so the marvels don’t stop when the sun goes down.

We think a trip here is one of the best day trips from Phoenix, AZ!
