Class b camper van, site #18, October 2020. Beautiful campground, huge sites with concrete pads for camper and picnic table. Trash cans at each site! Nice paved road along river for riding bikes inside the park. Fun to watch the barges going through the lock and by the campground. Big sandy playground. The restrooms are dated but clean. The showers need a serious update. Loved seeing all the families enjoying the park.

Generally a nice facility with a wonderful view of the Cumberland River and the passing barges. But, the washroom facilities were poorly maintained. At one time, both stalls in the men's washroom were out of order and we had to use the women's washroom. This was fixed by the end of the week, but it was an uncomfortable time waiting.
