Bluespring Caverns

Over 50 smaller streams contained in 18+ miles of known passages combine in the main river passage to create America's longest navigable underground river. Living in the miles of flowing streams are rare blind cavefish and blind crayfish. Passengers on the custom electric tour boats can usually sight some of these unusual creatures as they float though the winding passages.

Cumberland Caverns

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.
