If your a non-resident this place is too expensive. There are several other campgrounds in this area that are priced right.
We camped at Fairy Stone State Park last weekend and it was a wonderful experience for our family of 4! We camped in our small Starcraft RV which is under 18 feet. Every single space is very shaded and has electric and water hookups. Bathrooms and showers were clean. We are VA residents so it was $30 per night, but that includes swimming passes to the lake too (which otherwise would have cost us $14),so its a good deal if you plan to swim! You do need to drive (or ride a bike to the lake beach). Make sure you select a GREEN campsite, because they tend to be bigger than the yellow which are also used by tent campers. 7 of the 8 green sites are pull thru and can accommodate a larger RV. Yellow sites have a gravel pad for tent campers and are pretty short so not good for large RVs. We loved it there and plan to go back!
Nice State Park with plenty of hiking trails, a lake with a beach and swimming, and "fairystone" hunting. The campground, although small, is nice and well maintained. Bathhouse is fairly new. Sites are very small for RV's. I wouldn't bring anything much bigger than 22' long here.
