Tennessee is a road-tripper's dream: Visitors can wind their way down from the Appalachian mountains to the rivers and corn fields below, stopping at cities spaced just far enough apart for a rest, refuel, and repeat. Along the way, nature enthusiasts will fall in love with hiking in the Great Smoky Mountains National Park, river rafting on Pigeon River, and opportunities for adventure amid the rivers and foothills of the eastern part of the state, punctuated by the cities of Knoxville, Pigeon Forge, Gatlinburg, and Chattanooga. Views of the blue-hued mountains from the many stopping points along the roads near the Great Smoky Mountains National Park are not to be missed—or for something special, see the landscape from above by helicopter.
