Cave of the Mounds is a National Natural Landmark in Blue Mounds, Wisconsin. The natural limestone cave was discovered in 1939, but its formation began much earlier, approximately 488 million years ago.

The Chicago Academy of Sciences considers the cave to be of significance to the Midwest, and thanks to its wonderful beauty, it is known by many as the ‘jewel box’. Beyond its stalactites, stalagmites, and columns, the Cave of the Mounds also has other interesting formations such as thin soda straws, lily pads, and angled helictites. The cave is accessible on a walking tour that visitors of all ages can handle easily.
