The range's highpoint, Roan is clad in a dense stand of Southern Appalachian spruce-fir forest, and includes the world's largest natural rhododendron garden, and the longest stretch of grassy bald in the Appalachian range. The Roan Highlands also contain the highest quality remaining stretch of Fraser fir forest throughout the tree's entire range. The Cherokee National Forest and Pisgah National Forest converge atop the mountain, with Roan Mountain State Park located near its northern base. The Appalachian Trail traverses most of the Roan's crest. The Roan High Knob Shelter is the highest back-country shelter on the entire 2,174-mile trail.
