Yes. The "official" AT is marked with white blazes, and other, nearby trails are often (always?) marked with blue ones. Blue blazing the AT might include taking the BMT from Springer through GSMNP. Or something like that. Since the AT has been re-routed over the years, one could conceivably hike the trails that used to be the official route but are no longer.

But I don't know firsthand because I've never been through there. I got all this online.
