Really clean campground, well maintained and the hosts are great! Sites are large a flat - only downside is the road.

Flatrock is a very nice campground. The sites are far apart and so you have privacy. The electric sites are a real plus. The camp hosts were really wonderful, making our stay(s) very pleasant. They kept the restrooms clean and well-stocked. The only draw back of this campground is the noise from the highway. A lot of big trucks using exhaust breaks at all times of the day and night.
