Ohio Caverns is the largest and most beautiful of all Ohio Caves. Its exquisite crystal-white stalactite and stalagmite formations are nowhere to be found in greater profusion of artistic settings.
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.
