Dan and Annie were by far the best camp host we have experienced. This was our first time going to the Yellowstone area and they made the campground top notch. Lots of help and we would visit again any time.

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.
