I had to make a last-minute reservation for a campsite on my drive back from Maine to DC on a Friday night in September, so was a bit worried about finding anywhere decent at all. This campground was one of the few with any sites available, and I got the second last spot. So I had pretty low expectations.
Actually this campground is pretty nice--the campsites are of a normal size, with enough rocks and trees between sites to provide a decent amount of privacy. Again, my campsite was one of the worst, right on the road, but still not too bad. It would have been pretty decent if every campsite around me hadn't been full, generally with families with a bunch of shrieking kids. But that's a weekend in September...
There are also a limited number of campsites right on the water. The lake is nice enough, although much of it is covered in lily pads.
Bathrooms are fine.
No wood for sale on-site, but there are several places nearby to get wood, and any other supplies you need. The campsite is not exactly remote, I think it was about a 5 minute drive to a gas station with firewood and all manner of supplies.
I would definitely stay here during the week when it might be a bit quieter.
