Wister

A large state park on Lake Wister in the foothills of the Ouachitas, with several separate camping areas along the shoreline plus cabins. The lake is big enough for real boating and fishing but the campgrounds stay reasonably quiet, and the swimming areas are shallow and kid-friendly. Because the camping areas are spread out, it is worth asking which loop suits you before booking: some sit right on the water, others are set back in the woods. It pairs naturally with the Talimena Scenic Drive an hour to the west.
