I have not been north of Damascus but my picks would be as follows from north to south.

1. Blood Mtn. I probably would not stay here when Neels Gap is just at the foot of the mountain but regardless the views from the mountain are great.
2. Tray Mountain. The short side trail to the shelter has an awesome view.
3. GSMNP, if you have seen one in the park you have seen them all but Icewater has the best view but depending on the time of the year espect it to be a full house.
4. Overmountain is not be missed. Regardless of the amount of people it's plenty big enough and the view into the Roaring Creek valley is nice.
5. Vandeventer which has been mentioned more than once on this thread. The view down into Lake Watauga area is breathtaken but the trek to the water source is well....a bit challenging.
6. Hogback Ridge. It has been a little over 5 years since my stay there but if I remember correctly the view from the privy was nice, yeah I know that sounds weird but that's one of my memories of my stay there.
