(1 to 7 miles, moderate hike) Famous for its spectacular natural gardens of Catawba rhododendrons, Roan Mountain shelters a rich diversity of life, from spruce-fir forests to vast grassy balds. It is not one mountain, but a high ridge about five miles long, the highest point being 6,286 ft. Hike the ridge on the Appalachian Trail for sweeping views all along the way.
