Northern Virginia

In northern Virginia, the Appalachian Trail follows a long, low ridge, including a notoriously strenuous “roller-coaster” section south of Snickers Gap. It is less heavily traveled and is crossed by fewer roads than the Trail in Maryland. This is one of the best places on the A.T. for “spring break” hikes. Download Spring Break Hiking (PDF) to find out more about hiking on the A.T. in March and April.

The northern Virginia section stretches 54 miles from the Virginia/West Virginia state line south to Shenandoah National Park.

Shenandoah National Park

Shenandoah National Park, with 104 miles of well-graded and well-maintained Trail and climbs rarely exceeding 500 or 1,000 feet, is excellent for beginning hikers and is noted for its many vistas and abundant wildlife. A variety of side trails provides excellent opportunities for one- or two-day circuit hikes.

Nearby Skyline Drive has many waysides and concessions for resupply stops. The park gets very busy during weekends and in late October, during peak foliage-changing season. Park facilities close from late November through March; when snow shuts down Skyline Drive, the entire park may become inaccessible except on cross-country skis or snowshoes. Backcountry permits are required when camping in the park.

Central Virginia

South of Shenandoah, the A.T. parallels the Blue Ridge Parkway. The farther south it goes, the more difficult the hiking becomes; the treadway is well-graded, but includes a number of 2,000- and 3,000-foot climbs. Mature timber, high summits, and spectacular wilderness can be found in the George Washington National Forest, north of Roanoke. The Trail then leaves the parkway and travels west across the Great Valley of the Appalachians through the Jefferson National Forest to the Allegheny Plateau, a splendid wilderness trip.

Central Virginia features many noteworthy points, with views from unusual rock formations and outcroppings and some of the northernmost balds on the Trails. Noteworthy peaks include Humpback Rocks, Three Ridges, the Priest, McAfee Knob, and Dragon’s Tooth. This section is more rugged and remote than the Shenandoah, but easier and more accessible than the Trail in Southwest Virginia.

The Central Virginia section covers 226 miles from the southern end of Shenandoah National Park south to Pearisburg.

Southwest Virginia

Throughout the Mt. Rogers region in southwest Virginia, where the Trail moves into the southern Appalachians, the floral displays of rhododendron and azalea in June and July are outstanding. The state’s highest mountain, Mt. Rogers, an area of spectacular highland meadows, routinely receives snowfall from October to May, making it considerably colder, wetter, and snowier than other areas of Virginia.

The northern portion of this section provides some of the A.T.’s best opportunities for solitude; toward the southern end the open meadows of the Mt. Rogers high country (5,000 feet and above) attract many visitors. At the southern border is the quintessential “Trail town,” Damascus, Virginia.

The Southwest Virginia section of the Trail covers 166 miles from Pearisburg south to Damascus.
