Awesome motorcycle ride. It is a National Park. Speed limit is 45 and the Rangers have radar, behave. Abundant wildlife, breathtaking vistas, amazing hiking , plenty of waterfalls. Nature in a splendid form. Music and art venues, Museums. Mabrys Mill, Mt Airy, Nc. (AKA Mayberry).........Some of the highest points east of the Mississippi. Traffic slows after Labor Day. Then picks up for the leaf peepers. No Stop signs.
Going south ends in Cherokee, NC. Heart of the Smokey's. Coming north stay on it and run the Skyline (speed limit 35) to Front Royal, Va. There is a fee to run the Skyline Drive. If you include the Skyline I think it's 575 miles combined with the BRP. Only a few service areas but enough exits for Hotels and fuel. Plenty of camping opportunities.
If your in a hurry...don't bother. Relax and enjoy. As a motorcycle enthusiast I consider it a National Treasure, and one of the best rides in America.
