Norris Dam state park is a lovely place that includes this Grist Mill, and a museum of local artifacts.

Walden Ridge gives a great view all the way to the Smokies. It also has wonderful rock formations.
There is a road to the top of Walden Ridge off of Dutch Valley Road. There is a small sign saying "Fire Tower" at the foot of the road.
Once you reach the top of the ridge. you can park,  It you head SW, the path takes you to the Fire Tower. If you head NE, the path leads to these pretty rock formations.
