At 6643 feet, Clingmans Dome is the highest point in the Great Smoky Mountains National Park. Located in the northernmost part of Swain County along the North Carolina–Tennessee border, the temperatures at Clingmans Dome are often 10 to 20 degrees cooler than Bryson City’s. On a clear day, take the (steep) half-mile walk from the parking lot to the observation tower, and you’ll be rewarded with a stunning 360-degree view of the Smokies and beyond. The seven-mile road from US 441 to Clingmans Dome is open Aprll thru November. Photo by J.R. vanLienden, Masterpiece Portraits.
