Green River (Ferry & Canoeing)
Green River
A clear river running through the national park, where you can cross on a free car ferry or rent a canoe to paddle past cliffs and wildlife.
The Green River winds through Mammoth Cave National Park and is the key water source that shaped the cave system. The park still operates the rare Green River car ferry, which runs free every few minutes and forms part of the park's north-south road network. In summer you can rent canoes or kayaks from businesses near the park and paddle from Dennison Ferry to Houchins Ferry and other stretches, a trip of about 2 to 4 hours past limestone cliffs, riverside springs, turtles and herons. The river has very high mussel diversity, so please do not collect shells. Stop paddling when water levels rise after rain.
Opening hours
Ferries approx. 6:00 am–9:55 pm (subject to water level)
