Kartchner Caverns Cave Tours

category : Caving
Kartchner Caverns Cave Tours Kartchner Caverns has been meticulously preserved and offers tours of the Rotunda and Throne Room throughout the year and visitors can take the Big Room Tour from October through April. The Big Room is generally closed in late April when the myotis bat returns from Mexico to give birth, transforming the cavern into a giant bat maternity ward deemed essential to the cavern's delicate environment. All three rooms give visitors close-up views of the beautiful, astonishing and still-growing formations.

Kartchner Caverns' wide variety of decorations, called "speleothems", began forming drop by drop over 200,000 years. Water seeping from the surface dissolves minerals on its trip through the limestone. Once it reaches the cave, the trapped carbon dioxide escapes from the water. No longer able to hold the dissolved calcite, the drop deposits its tiny mineral load. Over time, these minerals have created the beautiful speleothems and variety of colors found in the cave. Kartchner Caverns is a "living" cave; the formations are still growing!

Rotunda/Throne Room Tour: Length: 1/2 mile Time: 1 1/2 hr. (leaving approximately every 20 minutes), tours available year-round.

On this tour you will discover the role water has played in the creation of Kartchner Caverns. You will see some of the tiniest, most delicate formations found in the cave, as well as the largest column in Arizona. This tour includes an up-close look at the variety of formations and colors that makes this cave one of the top ten in the world. And for you music lovers...the music that's played at the end of this tour is entitled "Adiemus" (Virgin Records Ltd.).

Big Room Tour: Length: 1/2 mile Time: 1 1/2 hr. (leaving approximately every 30 minutes), tours available October 15 - April 15.

The Kartchner Caverns story is one of amazing discoveries...both past and present. Stand where the discoverers first entered the cave. Marvel at the strange and colorful formations. Learn about cave inhabitants, both ancient and living. As scientific studies continue, discoveries are yet to be made. The Big Room tour is a longer and more physically challenging tour. Children age 6 and under are not allowed on the tour.

During the summer months, the cave's Big Room serves as a nursery roost for over 1,000 female cave myotis bats. The pregnant females return to Kartchner Caverns around the end of April, where they give birth to a single pup in late June. The babies remain in the roost each evening while their mothers forage for insects in the surrounding countryside. During the summer the colony consumes about half a ton of insects, consisting of moths, flying ants, beetles, mosquitoes and termites. Mothers and their offspring will leave mid-September, to begin their migration for their winter hibernation roost. These bats provide the only link between the ecosystem of the cave and the surface. After returning to the bat roost from their nightly forays, the bats excrete waste, forming large guano piles. Most of the other life forms found in the cave depend on these guano piles for their food. Fungi and bacteria consume the guano first. These are in turn eaten by nematodes, mites, isopods, amphipods, and book lice. These are then eaten by spiders, scorpions, mites, millipedes, and centipedes. Scavengers, like crickets and beetle larvae, clean up the leftovers. The bats' guano provides the energy needed to run this complex food chain.
