Voted "Best Arizona Attraction" by USA Today
2017 Reader's Choice Awards.
Enter a secret underground world millions of years in the making — bounding with exotic cave formations rarely seen elsewhere. Marvel at nature's creations in this living and contained ecosystem. Discover delicate soda straw formations, gravity-defying helictites, drapes of waving flowstone, and the grandeur of Kubla Khan — a formation standing six-stories tall.
Visitor Tip: Selecting a Tour Time
Plan to arrive at the park at least 30 minutes prior to the start of your first tour. This will allow you enough time to check in, learn a bit about the cave and orient yourself to the facilities. Note that commuter traffic from Phoenix and around Tucson can increase your travel time, so plan ahead for potential delays.
