Little Oak Campground
I have no idea what their season is, but they are on Holston Mountain. You can access it from HWY 421 or from the Hickory Tree area. If I can get any more info on their season I will post again. I think someone else on this board was thinking about coming up to East TN and hoping to stay there. It's a gravel road but doesn't take too long to get in and out.
