Tucson’s Colossal Cave

Colossal Cave, part of the National Register of Historic Places, was discovered in 1879. Tours were first began in 1923 via ropes and lanterns. Colossal cave was thought to have been used by the Hohokam Indians between 900-1450 A.D.  It is thought that the Hohokam used the cave for shelter, storage and as a shrine. Today, the cave tour has lights and handrails to make exploration easy and enjoyable. This “dry” cave, meaning that it is no longer growing by being fed by mountain streams that once dripped through the earth in this area, has a great selection of stalactites and stalagmites of various hues to offer the cave explorer.  The temperature is always a cool 70 degrees F. inside so this cave is a great place to tour even during the hot Arizona summers. The park is open from March 16 to September 15 from 8A.M. to 5 P.M. and from September 16-March 15 from 9 A.M. to 5 P.M. The cave tour costs $11.00 for adults and $6.00 for children between the ages of 5-12. Children 4 and under are free. Other more specialized tours are also available such as a Candlelight Tour or a Ladder Tour. Call the park office for more information if you are interested in any of the more specialized tours since many require advance reservations. Camping in the park is permitted and horseback rides are also available.To reach the cave, take I-10 east from Tucson to exit 379 (Vail/Wentworth exit), turn north and follow the signs.
