The Great Smoky Mountains are a mountain range rising along the Tennessee–North Carolina border in the southeastern United States. The park usually experiences an autumn leaf season of several weeks as fall colors travel down the mountain sides from high elevation to low. Each year the mountains puts on a beautiful show and with all the different elevations in the different mountain areas. Elevation profoundly affects when fall colors change in the park. At higher elevations, where the climate is similar to New England's, color displays start as early as mid-September with the turning of yellow birch, American beech, mountain maple, hobblebush, and pin cherry. From early to mid-October, fall colors develop above 4,000 feet. To enjoy them, drive the Clingmans Dome Road, the Blue Ridge Parkway, or the Foothills Parkway.
