Kartchner Caverns State Park

Kartchner Caverns is one of the most carefully protected show caves in the United States. Two amateur cavers, Gary Tenen and Randy Tufts, discovered it in 1974 and kept its location secret for years to protect it. Arizona later acquired the land and developed it as a state park, opening to visitors in 1999 after careful planning to preserve the cave delicate environment. It lies about nine miles south of Benson, roughly a thirty-minute drive from Tombstone, and offers a refreshing contrast to the dry desert above. Unlike many caves, Kartchner is a living cave, which means that its formations are still growing. Tours pass through chambers decorated with stalactites, stalagmites, columns, soda straws, helictites and other delicate forms. The park uses airlocks, misting systems and low lighting to protect the environment, and guides explain how the cave formed over hundreds of thousands of years. Above ground, the park has a discovery center, a campground, trails and picnic areas.

Tours are guided and limited in size to protect the cave. Visitors typically choose between the Rotunda and Throne Room tour, which is available year-round, and the Big Room tour, which is closed during part of the year when a colony of bats uses the room for raising young. Check current tour offerings, schedules and reservation requirements with the park, because tickets are often limited and busy periods sell out. Plan to book well in advance for weekends, holidays and winter months, when visitors from colder climates come to southern Arizona.

The temperature inside the cave is steady and humid, so dress in light layers. There are rules to protect the cave: no touching formations, no food or drink inside, and restrictions on bags and cameras. Check the policy on photography. The tours include walking on paved paths and some stairs, and the park provides information about accessibility. Children are welcome on the tours, but they must be able to follow the rules. Allow time before your tour for the discovery center, which explains the geology and the discovery story.

Kartchner works well as a half-day add-on to a Tombstone and Bisbee itinerary. Many travelers visit in the morning and continue to Tombstone in the afternoon, or stop on the way between Tucson and Tombstone. The nearby town of Benson offers hotels and restaurants. If you enjoy outdoor activities, the park trails and campground add options, and the Sonoita and Elgin wine country is another half-day option nearby. Check for seasonal events and special tours, as the park occasionally offers extended programs.

Allow time to explore above ground. The Discovery Center presents exhibits on the discovery of the cave, the science of its formations and the bats that live there. Short trails lead through desert plants, and the campground offers a chance to stay close to the cave for early tours.

In winter, mornings can be cold, and in summer the temperature difference between the hot surface and the cool cave is dramatic, so a light jacket is welcome. The gift shop stocks books on caves and local natural history, and the park hosts seasonal programs worth checking before you go.
