In Mammoth Cave National Park, you can camp on a river island, rough it on the floodplain, or find a spot with a river view at Houchin Ferry Camgound.

Camping along the floodplain is by permit only. With a free Backcountry Use Permit, you can camp on riverbanks and islands along the Green and Nolin Rivers. Be sure to camp at least ½ mile away from Green River Ferry, Houchin Ferry and Dennison Ferry Day-Use Area. Pick up your Backcountry Use Permit and a copy of the rules and regulations at the Mammoth Cave Campground. Remember that if putting in upstream at Munfordville, riverside camping may not be permitted on private lands outside the park. Your Backcountry Use Permit is only valid within Mammoth Cave National Park. For a backcountry map click the following link: Backcountry Map & Guide.

When setting up your campsite on islands or on the riverbank, remember that sudden rainstorms can cause rapid flooding. Know the weather forecast so you can anticipate weather-related problems. To hear the National Weather Service forecast in the area, tune your radio to AM 530.

River levels and current fluctuate dramatically, particularly during the winter months, and snags or sandbars may be hidden underwater. Observe weather conditions. Flooding is possible. In case of storms, leave the water and seek shelter.

A number of regulations apply when you camp in the park. Please read the following Backcountry Camping Rules and Regulations before camping, and obtain a copy for your trip at the Mammoth Cave Campground when registering.
