Clingmans Dome is 6,643 feet which makes it the highest point in the Great Smoky Mountains National Park. Clingmans Dome is also the highest point in Tennessee, and the third highest mountain east of the Mississippi. Mt. Mitchell reaches 6,684 feet which is located in Mt. Mitchell State Park in western North Carolina and is considered the highest point east of the Mississippi.
The observation tower on the summit of Clingmans Dome offers spectacular 360° views of the Smokies and beyond. There is a steep half-mile walk to the top of the tower. On a clear day views expand over a 100 miles. But, because of air pollution you are only able to see about 20 miles.
Due to weather conditions, the road to Clingmans Dome is closed December 1 through March 31.
