We stayed at backpacking site B. In our opinion the best backpacking site in the island. It's secluded, tree covered but offers great views of Lake Michigan. The backpacking sites are only 1-2 miles from the dock. The park/island itself is only roughly 7 miles. There are a few trails to hike, a lighthouse to explore and the dock area. They do have a small building that contains outdoor equipment(balls, frisbees,bocce ball etc) to use. It's a nice relaxing little adventure. Ferries come a few times a day to pick up/drop off, approx 15 min ride from Washington island. Bugs and flies can be bad so be prepared :) as fare as the campground goes, sites 15 &16 supposed to be the best, again in our opinion.
