Today, Cumberland Caverns offers walking tours, adventure tours, overnight cave camping, concerts and more in this beautiful National Natural Landmark site.

Limestone Caves

Learn About Caves!

Most caves are solutional caves, often called limestone caves for the common type of soluble rock in which they form. The caves form as groundwater dissolves quantities of soluble rock by seeping along joints and faults.
