We found this park to be well laid out with many sites on Lake Huron and several pull-thrus just inland. Pull-thrus are large but trees can be a problem, we found it easier to back into our site. Roads are paved but somewhat narrow with fairly tight turns for larger rigs [we have a 40' Class A] but we had no problems. Like most State Parks no water or sewer, but 50 amp at many sites! The dump station is in a odd location requiring a some tight turns or a lap around the campground. A good place to base camp from to explore the Au Sable River and Huron National Forest. The town Harrisville is quaint with a nice marina. Reservations can be made on the Michigan DNR website. We would stay here again. We camped here in a Motorhome.
