Get away from the crowd
6 miles west of Fort Robinson on Soldier Creek Rd. First come first serve, $15 per night and only 6 spots available if I remember.
This area is used frequently by those riding horseback as there is a horse corral next to a couple of the campsites to the south.
If you like to hike and fish there I'd a trail that goes west from the campsites 1.3 miles to 3 ponds filled with brown trout.
