Kartchner Caverns were discovered in 1974.
This “live” cave “is host to a wide variety of unique minerals and formations. Water percolates from the surface and calcite formations continue to grow, including stalactites dripping down like icicles and giant stalagmites reaching up from the ground.”
Tour guides unveil fascinating underground discoveries during two memorable 1½ hour tours. The year-round tour covers the Rotunda/Throne rooms; the other, the Big Room, is open only for six months, Oct. 15-April 15, because of a resident bat population the other six months of the year.
The Discovery Center features museums exhibits, a large gift shop, regional displays, theater, and educational information about the caverns and the surrounding landscape.
