In my fly fishing & camping around and about that area, use to visit a little National Forest Campground just a little way out of Helen, called Low Gap Creek. Was good fishing and for the most part like those little National Forest C/G's - they certainly are scarce for amenities but that thins the crowd out and for the most part there are only fisherman. Also, the site rent is certainly inexpensive.

Anyway, here's a reference site that might help.
