The most significant cave in the upper Midwest, Cave of the Mounds is located just 20 miles west of Madison, Wisconsin. The U.S. Department of the Interior designated Cave of the Mounds a National Natural Landmark because the site possesses exceptional value as an illustration of the nation's natural heritage and contributes to a better understanding of man's environment. A one hour guided tour of the Cave takes visitors through a beautiful collection of colorful stalactites, stalagmites, columns and other mineral formations.
