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.

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.
