Colossal Cave Mountain Park

Colossal Cave Mountain Park Review

This limestone grotto 20 mi east of Tucson is the largest dry cavern in the world. Guides discuss the fascinating crystal formations and relate the many romantic tales surrounding the cave, including the legend that an enormous sum of money stolen in a stagecoach robbery is hidden here.

Forty-five-minute cave tours begin every 30 minutes and require a 0.5-mi walk and climbing 363 steps. The park includes a ranch area with trail rides ($30 per hour), a gemstone-sluicing area, a small museum, a desert tortoise habitat, nature trails, a butterfly garden, a snack bar, and a gift shop. Parking is $5 per vehicle. Take Broadway Boulevard or 22nd Street east to Old Spanish Trail.
