How do you intend to get to Deal's Gap from where you will be?
The Cherohala Skyway is an awesome road and should be ridden while up there.
There are so many great roads for riding in that area, it's really hard to single them out, so I won't.
Highway 64, between Franklin and Brevard.
Highway 178 from Rosman, NC to Pickens, SC.
Highway 107 from Cashiers.
Highway 68 - runs through Tellico Plains - either north or south - great road.
Like I said there are just so many roads and never enough time!
Enjoy! I'm taking the Strom up there in October!
