Blue Ridge Mountains, an eastern range of the Appalachian Mountains. It extends southwestward from southern Pennsylvania to northeastern Georgia, some 550 miles (885 km). In general, peaks are fairly rounded, heavily wooded, and higher in the southern part of the range. The highest elevations in Virginia, North and South Carolina, and Georgia are in the Blue Ridge Mountains. North Carolina's Mount Mitchell, rising 6,684 feet (2,037 m) above sea level in a range locally called the Black Mountains, is the highest peak in the eastern United States.

Many water gaps occur in the mountains, including the historic water gap at Harpers Ferry. Skyline Drive, in Shenandoah National Park, the Blue Ridge Parkway, and the Appalachian Trail, a footpath, follow roughly the crest of the mountains and provide spectacular views.

The name Blue Ridge is also used for a physical region of the Appalachians consisting of the Blue Ridge and Great Smoky mountains and other ranges.
