IMO, the best campground in the area is Ontonagan Township Park.
http://www.ontonagontownshippark.com/.
There are numerous sites next to the sandy beach, very reasonable priced, and unbelievably can swim in Lake Superior, which I did twice this year, in August and mid September.
The one negative is they do NOT accept reservations. Campers can call at 8 am on arrival day to request a site, the staff will place an orange cone with your name on an envelop on an available site.
Site 38 is the smallest site, all sand. Site 28, 29 are full sun and sand.
I have stayed in site 41 and 66.
Newer pay showers, .75cents for 3 minutes.
Last summer Porcupine Mountains Wilderness state Park campgrounds shower facilities were being upgraded.
Enjoy your experience in the UP.
