We stayed at the Big Island Campground in the beginning of August. The sites seemed pretty large to us. My kids loved skipping rocks at the little shore at the entrance to the big island. You cannot swim in the lake but there are canoes and kayaks to rent. We really enjoyed our time here. Rangers were super nice and helpful. We hiked about 5 miles, saw a few deer and other animals. Bathrooms were very nice and clean. All of us that remembered to reapply bug spray didn't have any bites.
