Just got back from Hocking Hills KOA in Ohio and was pleasantly surprised with how awesome the campground was. I usually avoid Private campgrounds like the plague but the sites at this campground are spread apart and the campground was meticulously maintained. The bathhouses were awesome (better than any campground I have ever stayed at)! Here is a few photos of the campground and some hiking we did while camping.
