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.

Vistas from Clingmans Dome are spectacular. On clear, pollution-free days, views expand over 100 miles and into seven states. However, air pollution limits average viewing distances to 22 miles. Despite this handicap, breathtaking scenes delight those ascending the tower. It is a great place for sunrises and sunsets.

Although Clingmans Dome is open year-round, the road leading to it is closed from December 1 through April 1, and whenever weather conditions require. People can hike and cross-country ski on the road during the winter.
