This park is a gem if you are looking for something close to Yellowstone (the address is Cody, WY, but the park is actually 3 miles from the east entrance), but there are no hookups. The park can accommodate large rigs, and there are some pull through sites, and a couple of sites right on the river. Our site was fairly level. The scenery is awesome. We would stay here again. We camped at Three Mile Campground - USFS in a Motorhome.
