Lewis & Clark Cavern

LEWIS AND CLARK CAVERN
This spectacular Montana State Park is an underground wonderland of colorful limestone shaped by Nature into weird formations of stalactites, stalagmites, clustermites and flowstone. The three-quarter mile path is naturally air conditioned, electrically lighted, and dry and safe to explore. Located just off U.S. Highway 10 S. in Southern Montana.
