It seems nearly every cave in the Southwest has its legends of bandits and buried loot, and Colossal Cave—which isn’t exactly colossal but is certainly impressive—is no exception. A 45-minute tour through this cavern combines a bit of Western lore with a bit of geology, for an experience that both kids and adults will enjoy. Although there was much damage to the formations here before the cave was protected, the narrow passageways and dramatic lighting keep the tours interesting. For more adventurous types, some tours venture into little-visited parts of the cave. This private 2,400-acre park, southeast of Tucson, also offers horseback riding ($47 for a 1-hr. ride) and has a small museum, picnic areas, snack bars, and a gift shop.
