Wow. I never realized how good we have it - about an hour and half away from 1000+ square mile Cherokee National Forest - this is the primitive camping policy...
"For visitors wanting to get away from it all, dispersed camping outside of developed campgrounds is allowed throughout Cherokee National Forest unless posted otherwise. Camping is not allowed within 100 feet of water, trails, trailhead parking lots and developed recreation areas. Dispersed camping is free and no permits are required."
Having taken advantage of it many times I can tell you that litter and abuse is NOT a big problem - negligible if you get just a short walk away from the road. May and October are prime times to visit if you get the chance BTW - but the best time is when it's cold enough to keep the crowds at the mall. Better do it soon before someone detects frackable gas under it.
