Great Smoky Mountains National Park transforms into a vibrant canvas of colour in autumn. America's most-visited national park has over 800 miles (1,287km) of trails, where hikers can experience breathtaking panoramas, especially from the Clingmans Dome observation tower, which stands at 6,643 feet (2,025m). For an aerial spectacle, hop on the Aerial Tramway to the Ober Mountain Adventure Park & Ski Area. Also not to be missed, the Unicoi County Apple Festival celebrates Appalachian heritage in early October, showcasing food, crafts and entertainment. Innovative accessible viewfinders, at lookouts across the state, provide colourblind visitors a chance to appreciate the fall colours.
