It's fine, not great.
This is an extremely primitive place that is not run by the Ohio Department of Natural Resources. It is run by the same woman who runs the boat rentals at several other state parks in SE Ohio- this is her business. There are very few amenities here. There are pit toilets, potable water towards the front, and that's it. There is a road that runs alongside the entire length of the campground, right at the edge, so you can hear cars and coming and going, especially at night. I was here in late October, so I can't attest to whether this place has a loud party atmosphere like many other state parks, but it seemed pretty chill, probably due to the fact that you can't reserve a site in advance- you pay when you arrive, and pick your spot then. The boat house's hours said they were still open for the season, but I arrived long after they were supposed to open according to their hours listed on the door, and I never saw a person all day. So I went to go rent a boat at a different place. All in all, the campground is fine, just the traffic along the road was a bit annoying, and the sites are not very wide- you are close to your neighbors and there is nothing separating the sites.
