Very large open gravel and prairie area. Long drive from there entrance to sites on gravel roads. Sites near water are still about 100-200 yards from the water. Lots of wind, no trees. The basic sites have a table, grill, parking pad, and tent pad, all on gravel. The area is very large so getting to the bathroom is a hike. Requires reservation plus a park pass you can buy at an automated kiosk. Access to site is via the visitor center boat inspection area which has the self serve kiosk. Overall the site is fine, and when I went on a weekday in July there was only one other camper in the whole area - right next to me. The water is pretty but that's probably where others will camp just FYI.
