Try Clayton or Dillard Ga. It's in the foothills of Great Smoky Mountains on 441 headed toward Cherokee NC. Dillard is right on the Ga./NC line. I know there's a campground or two, just don't know the name. Also, there's Tallulah Falls Gorge just south of Clayton. I think there's camping there. Driving on 441 will be fine. You can then unhook and drive farther up a mountain to sight see or go to Highlands, Cashiers, Cherokee, Maggie Valley, or Asheville NC.
