Escape the Arizona heat by going down under and taking a tour into the incredible Kartchner Caverns.
Discovered in 1974, Kartchner Caverns is home to remarkable minerals and formations
The caverns are carved out of limestone and filled with spectacular speleothems which have been growing for 50,000 years or longer. This tourist site holds the world’s largest stalactite formation. (A stalactite is a type of formation that hangs from the ceiling of caves, hot springs, or manmade structures such as bridges and mines.)
The 23,000-square-foot Discovery Center is another must-see at Kartchner Caverns. The center explains many aspects of the cave, including geology, the bat population and paleontology. Interactive exhibits help to explain the discovery of the cave and how formations develop.
