Right on the river, which is interesting, but it's also right alongside State Route 33, so you hear freeway traffic constantly. Trucks and motorcycles woke me up all night, AND there is a train track right across the river (about 200 yards away), so be prepared for trains coming through any time of the night or day.
It has flush toilets, which worked fine Friday and Saturday, but all of the women's toilets were clogged by Sunday morning, and the shower house needs to be hosed down- covered in dead bugs. Showers have this weird slimy grate on the floor- bring flip flops. The shower house is up on top of this steep hill, so you'll need a flashlight to get there in the dark.
The sites are very close together- one family moved in late at night practically on top of me- their tent was literally 4 feet from my picnic table. I could hear every word they said (or yelled) all night long. I moved down one site for a little peace and quiet, but be prepared- when crowded, you will be right on top of groups less than 12 feet to the right and left of you.
It's nice that the sites are right on the Hocking river, and there is constant traffic of canoes and kayaks going past. I thought this was fun. There is no way to put your own boat in here, though. The campground is on a very steep, muddy embankment and even putting in a lightweight kayak is very difficult (I tried and succeeded, but hurt my knee and fell into the water because of the mud- I wouldn't try this again).
All in all, I had a decent weekend, but I wouldn't stay here again because of the freeway noise and the way the sites are so close together.
