On 28 south of Franklin as you pass over the mountains there are several waterfalls. One you can't miss and you can park your bike under. The others are marked with signs. In Highlands stop and walk around downtown for a few minutes. Cool resort town with neat shops. The scenic overlooks are clearly marked the whole time you are down there. If you have time, blast over to Maggie Valley and hit the Wheels through Time motorcycle museum. Awesome museum, he had a show on Discovery or one of those cable channels for awhile. Very cool dude, if he is there ask him to do some burnouts. He will, right in the museum.

If you go to it you can make it a nice day trip, stop in Pidgeon Forge/Gattlingburg too..hit a bit of the BRP.

That also gets you on Foothills Pkwy. One of the best roads down there, especially the way you ride. Even if you just round trip that road you will love it. It is just north of the Dragon off 129.
