Mammoth Cave Campground is the closest of the three campgrounds to the visitor center at Mammoth Cave. You can drive and follow the signs to the campground. In this video, I followed the trail from Mammoth Cave Hotel to the campground. Visit Us: https://nationalusparks.com/ The other campgrounds are Maple Springs campground and Houchin Ferry campground. You can also backcountry camp which is the best. Have fun!
