There are two loops of campsites at Au Sable. The lower loop has nice vault toilets and fairly private campsites if you are on the east end. The campground is next to the Au Sable Lighthouse trailhead and the North Country Trail passes through, so in the daytime it is fairly busy. Not far from your campsite is a short walk to the beach where shipwrecks litter the beach. If you hike out to Au Sable Lighthouse in the summer you can feast on wild blueberries.
