My favorite in that area is Plum Nelly in East Elijay. To me, it is a throw-back to the 50's campground. Definitely not a resort. Owner and wife very friendly, mgr very nice. South of WalMart about 2 miles... on west side of road. On the east side of the road, two apple houses (peaches in summer.) About 25-30 miles south of Blue Ridge.
I have also stayed at Choestoe Falls In Blairsville, owner owned and it is very nice. Rent from the owner of the lot.
A couple of state parks in the area also.
Beautiful area.
