Rock City near Chattanooga, Tennessee
This may not be immediately in Tennessee, but it is right outside of Chattanooga, TN. Located at lookout mountain in Georgia, it overlooks the Chattanooga valley. This is a great tourist location with half a million people visiting each year, must be something nice there.
According to http://www.seerockcity.com you can take a walking tour that lasts up to 90 minutes through their trails. They have huge rock formations that date back a couple million years.
Supposedly you can actually see seven states at the same time Tennessee, Georgia, Alabama, North Carolina, South Carolina, Kentucky, and the supposed one Virginia. Virginia is a good 150 miles away.
