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.
