Various flowstone formations can be seen in this one-of-a-kind cavern system.

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 1? 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.

Nature of the Area
Rainwater, made slightly acidic by absorbing carbon dioxide from the air and soil, penetrated cracks in the down-dropped limestone block and slowly dissolved passages in it. Later, lowering groundwater levels left behind vast, air-filled rooms.

Kartchner Caverns' wide variety of decorations, called "speleothems," began forming drop by drop over the next 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!

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.

History of the Area
It wasn't until February 1978 that Tenen and Tufts told the property owners, James and Lois Kartchner, about their amazing discovery. During the four years of secret exploration, the discoverers realized that the cave's extraordinary variety of colors and formations must be preserved.

The cave's existence became public knowledge in 1988 when its purchase was approved as an Arizona State Park. Extraordinary precautions have been taken during its development to conserve the cave's near-pristine condition.

Camping
A two loop Campground is located off of the main road past the Discovery Center on the southwest end of the park. Campers must arrive prior to 6 pm before the park closes. Camping fees are payable with cash, Visa or Mastercard at the Contact Station or in cash at the self pay station located at the Campground entrance.

The Guindani Trail (#398), located on the east flank of the Whetstone Mountains in the Coronado National Forest, is 4.2 miles in length (first mile is an easy walk, next 2/3 of trail is moderate difficulty, and the last leg is strenuous). This is a shared-use, non-motorized trail that is well-marked with directional signs.

Trail elevations range from 4750' at the park trailhead to over 5620' at the highest point along the Guindani Trail. The summits along the crest of the Whetstone Mountains are over 7000' in elevation. Vegetation is mesquite-invaded Chihuahaun semi-desert grassland at the lower elevations and open oak-juniper woodland on the higher slopes.

Access to the Guindani Trail is located on the west side of Kartchner Caverns State Park campgrounds; a kiosk marks entrance to trail. For more information, contact: Sierra Vista Ranger District, 5990 W. Hwy 92, Hereford, AZ 85615 or call (520) 378-0311.

A short spur trail at the upper portion of the Foothills Loop Trail leads visitors to the scenic Mountain Viewpoint.

Informational signs along the Foothills Loop Trail will discuss such trail highlights as the foothills, scenic view, riparian area, bedrock mortar and the Native Americans that inhabited the area.
