Incredible sunsets are one of the many rewards of hiking along the Appalachian Trail, a national scenic trail that stretches from Georgia to Maine. Native to the Appalachian Mountains, rhododendrons bloom in this gorgeous photo that was taken along the trail near the Roan Highlands on the border of Tennessee and North Carolina. With so many great vistas to choose from, this scenic area is a favorite with day hikers and backpackers alike. Photo courtesy of Serge Skiba.
