Cumberland Caverns is the longest known show cave in Tennessee. Originally known as Higgenbotham Cave and Henshaw Caves, a connection discovered in the 1950s made Cumberland Caverns over 27 miles long, with more passageways still being explored in the far reaches of the cave. Today, Cumberland Caverns offers walking tours, adventure tours, overnight cave camping, concerts and more in this beautiful National Natural Landmark site.
