The non-main toilets weren't really clean / usable, lots of bugs. Main bathroom + shower room is best. Side patio with table was nothing but dirt. But everything else was excellent.

Got in on a Thursday afternoon around 1 pm. Check-in time was 3 pm which is strictly enforced due to the road leading into the campground being extremely tight, having campers entering and leaving the campground area at the same time would be a disaster waiting to happen. We parked at the Welcome Center and hit the Old Man's Cave Trail which is located right there. The trail was very easy and well-taken care of, you get to see a lot of awesome sights. 3 pm hit and we were able to check in and make our way into the campground area. The hill leading into the campground has a very high grade and it is a bit long. If you're towing with a smaller vehicle or have a larger trailer you may run into issues, just take it slow. Hearing some of the vehicles scream up the hill really made me feel sorry for their transmissions. There are several water supply stations throughout the campground. It didn't make a difference to us, we tow our rig with an F250, but if you're concerned about the steep grade of the hill entering the campground, then I suggest you wait to fill up until you actually enter the campground. It's just as convenient and could save you a decent amount of weight to tow uphill. We booked site 97, which is directly to the left as soon as you get to the top of the hill leading into the campground. I will say that the staff member that checked us in advised us to fill up our fresh water tank at the Welcome Center prior to entering the campground area. This is not necessary. Our site was decent. Smaller than I imagined it to be. We had a concrete pad that required about 3 to 3.5 inches of leveling from side to side. From my observation most of the concrete pads on the sites were not level, some worse than others. We had 3 campers in our group and all had to do some side-to-side leveling. Even with my rig all the way to one side of the concrete pad my steps were still not able to be placed on the pad, it made for a difficult entrance into the camper. The concrete pad was plenty long, and I was able to fit my truck in front of my camper. The campground is very nice and clean. Several trails have access from inside the campground which was nice to not have to drive to every hike. The campground at night was very quiet and seemed to be an older crowd, at least where we were. The full hook-up sites seemed to be a little more lively with more children. The bathrooms and showers were clean and well-kept. After walking through the campground and scouting some sites for future trips, we both determined that sites 48 and up, even numbers, in the full hook-up section are by far the best. There are decent sites located throughout the campground, even in the electric-only section, but the full hook-up sites were definitely more appealing. The dump station was one of the better ones I've used, especially at a state park. It had access on both sides so two campers could easily dump at once. It was easy to maneuver through the dump station and took no time at all on a busy Sunday to dump. We will definitely be returning to Hocking Hills State Park Campground, that being said I would not reserve the same site again, I would try to get one of the full hook-up sites we liked or look for a larger site with a larger pad. The hiking was beautiful, but if it's a weekend expect a large crowd and in some cases difficulty finding parking.

For hiking and general beauty Hocking Hills State Park is a real gem hence the 4 star rating. Unfortunately the park campground isn't up to snuff (by itself I'd give it 2 stars. As others have mentioned the sites are close together with little privacy between them, better than most KOA's but not by much. On some loops the bathrooms are nice, modern facilities; those on the loop we were in were the pits (you know what I mean, like in the 60's :-( ). The cost quoted includes a $6.50 reservation fee. We were only there for one night and were glad we hadn't planned a longer visit. On the positive side everyone there was pretty friendly and the staff were nice. Most sites seemed fairly level, ours was only off by 3-4 inches over our 144" wheel base Sprinter.

The campground is ok. The sites are very close together but are paved and level. The bath house was a mess. We were her on a holiday weekend so there was a lot of extra traffic. The campground is close to a lot for great hiking.

Price paid was with Ohio Golden Buckeye card. Parking pads and roads are asphalt. Sites are nice but maneuvering a larger rig can be difficult. The hiking trails in the park and surrounding areas are fantastic.
