Denumbers is considered a back country campground in Land Between the Lakes. The road going back into the campground is paved, and the roads in the campground are compacted gravel. This is a well maintained campground whose only amenity is a vault toilet, and trash dumpster. The views of the lake are amazing, and this is a quiet area that allows for easy kayaking or other small water craft. There is a boat ramp, and zero entry areas into the water for launching.
A Dispersed Camping (Basic Camping) permit is required to camp here and you must purchase these at any of the three Visitor's Centers PRIOR to coming out! I've been told (by LBL LEO) that if you arrive after the centers are closed, but go get the permit first thing in the morning when they open, you will be good...
