We went in July. It was incredibly crowded. Many sites were set up as buddy sites so we had to share our outside space with our neighbors. It was tight and awkward.
There is zero internet and no signal which is fine for camping but made finding the weather or maps very challenging.
The roads are narrow and there are a lot of people. We did not kayak the river bc there were just too many people on the river, the water was low due to lack of rain this summer, and when we could see the grotesque adult behavior from the road, we knew we weren't interested in joining that mess.
The site was clean, it is full hookup, and they drive you to your site, which was nice. There is a fire bowl and picnic table for each site and dogs are allowed. Our pull through site was plenty level and accommodated our 33' camper and truck. There is a trail off the campground which is nice. The Mohican State park is full of great trails.
The campground is easy to find and everyone was very nice and the other campers are mostly respectful. There were a few cars and motorcycles that kept "cruising" around which felt strange but was likely harmless.
Photo was during checkout this the empty look. The two rigs in the photo are facing one another which is what I mentioned above.
