Mammoth Cave Campground is the main developed campground within Mammoth Cave National Park, featuring 111 tent and RV sites ($25-$50/night) with water access and flush toilets, located within walking distance of the visitor center and cave tours.

The campground provides convenient access to the Green River for fishing and paddling, with nearby boat launches at Green River Ferry and Houchin Ferry for canoe/kayak trips; anglers can fish for smallmouth bass and catfish from shore or via outfitter rentals.

Reservations through Recreation. gov are essential during peak season (March-November), and the park charges no entrance fee, though cave tours and water activities require separate fees.
