At 6,643 feet, Clingmans Dome is Great Smoky Mountains National Park's highest point. It is the highest point in Tennessee, and the second highest point east of the Mississippi. Only North Carolina's Mt. Mitchell (6,684 feet) rises higher.
Clingmans Dome is a popular Park destination. Located along the state-line ridge, it is half in North Carolina and half in Tennessee. The peak is accessible after driving Clingmans Dome Road from Newfound Gap, and then walking a steep half-mile trail. A paved trail leads to a 54-foot observation tower. The Appalachian Trail crosses Clingmans Dome, marking the highest point along its 2,144 mile journey. http://www.clingmansdome.com/
