Best kept secret in the area.

Flat camping sites, mostly pull thru, with fire rings, picknic tables. One vault toilet, always clean,always has paper. Campground is free and open all year. Some sites are alongside a pond, where I have seen people swimming. There is a short hiking trail to the river. Not far from the campsites is a boat launch.  I drive through this campground almost daily and in the last year have only seen it 80% full at the most.  Con: no electricity, no drinking water. Stay limit of 7 days. Very well maintained.

The town of Rosebud has a bar, that is open in the weekends, and serves dinner. 

The town of Forsyth is 15 minutes away, and has a grocery store, hardware store(s) and gas station(s). Also a one room movie theater, completely restored with lounge chairs. Forsyth has a bowling alley. Great place for camping, fishing, swimming, shopping, and relaxing.

I have good connection with Verizon here.
