Very nice campsites right on the Cumberland River. Well maintained and relatively clean. The men's restroom had no soap for one day even though the cleaning service had been in there as I was entering. Still all in all, I enjoyed my stay and I do like this campground.

Large clean sites. COE Campgrounds are always well maintained, clean, on water, and offer senior discounts. I always enjoy
staying there.

It was great, beautiful, kids and fun. We had a river facing site to watch barges go by. Mosquitos were intense

Reservation confirmation not honored. Showers filthy. No electricity to bathroom outlets. Hand dryers a joke, blowing cold air feebly. Would not return.

Army Corps of Engineers parks are the best managed, most enjoyable parks hands down! We stay almost exclusively at these parks. Lock A is beautiful, right on the Cumberland, so you can watch the barges go by.
