In the black hills, this is the area's largest stalactite cave and the closest cave to Mt. Rushmore National Memorial. The one hour tour winds through a series of rooms and passages, the most stunning of which is the BIG ROOM. This legendary room contains thousands of salactites, stalagmites, ribbons, helectites, columns and other breathtaking cave formations.
Situated on Hwy 40 between Keystone and Hermosa, the cave is easily accessible from all parts of the Black Hills.
