I have hiked the NC Bartram from Wayah Bald to Cheoah Bald in 2005 and I thought the section from Winding Stair Gap to Cheoah Bald was really great with lots of, streams, waterfalls, and cascades along the way. Cheoah Bald provides a superb panoramic view. It was a bit steep though!
Cheoah has 180 degree views, Rabun has 360 degree views (from a fire tower). If you are judging a hike by the views – pick Rabun. If you are making the call based on trail traffic – pick Cheoah. You have to really work to get to the summit – especially if you start from the NOC in Wesser, NC.
