Two viewpoints come to mind. One is Shuckstack Firetower, just off the AT about 5 miles north of Fontana Dam. Incredible views down to Fontana Lake. The other is Mt. Cammerer Firetower, .6 miles off the AT, about five miles south of Davenport Gap. Both are great, without car traffic crowds swarming around.

My favorite trail is probably the Forney Ridge/Forney Creek Loop, starting at the Clingman's Dome parking lot. Nice ridge walk down with a series of excellent campsites and stream crossing on the way back up.
