We parked our RV out on one of the campground fingers and had water on 3 sides of us. Swimming was available just adjacent to our side. Lots of kayakers making river runs from the other side of the dam. Another Corps of Engineers gem!

All sites seem to have 20/30/50 amp electrical options.

We hiked the Kevin R Brown trail which is the only one you can access from the campground.
