At 6,643 feet, Clingmans Dome is the highest point in the Great Smoky Mountains National Park. It is the highest point in Tennessee, and the third highest mountain east of the Mississippi. The observation tower on the summit of Clingmans Dome offers spectacular 360° views of the Smokies and beyond for visitors willing to climb the steep half-mile walk to the tower at the top.
