Kartchner Caverns

Benson, AZ

A Subterranean Wonderworld

Discovered and explored for the first time in 1974, Kartchner Caverns is massive limestone cave in Arizona just a few miles outside Tucson. Here visitors can experience one of the rarer natural wonders on earth: caves. The world’s longest stalactite formation and the world’s largest collection of brushite moonmilk make this underground phenomenon a must-see.
