Unless you own horses, like biting flies, and enjoy anything but the peaceful getaway you wanted, avoid this campground.
Seriously, I don't understand why they don't just call this "Cottonwood Patch Horse Camp" and stop misleading people. The flies here are some of the worst I've experienced and I've been in alpine areas when large flies are biting and buzzing. This was something else. The creek that runs through here is sluggish and and pools in many areas which provides perfect breeding ground for mosquitoes and other lovely insects.
The campground itself is overgrown and lacking facilities. It is in no way characteristic of the north GA mountains - it looks like it would be more fitting behind a dollar general in rural south GA.
The Forest Service has practically abandoned this entire area, as evidenced by the poorly maintained roads, dilapidated and/or missing facilities, overgrown campsites, and overall sad look of the place. If you're looking to camp in the area, don't. The Forest Service has turned it over to the hunters and horse riders to use and abuse.
There are signs for another FS campground just north of this one in Tennessee, don't bother, though the signs remain, the campground has been blocked off by boulders and is totally overgrown and abandoned. My guess is they leave the signs up because they don't care - it's sadly characteristic of the whole area.
