Shenandoah National Park
Shenandoah National Park 198,081 acres (80,195 hectares), N Va., extending 80 mi (129 km) along the crest of the Blue Ridge. Authorized in 1926, it was fully established as a national park in 1935. Skyline Drive, a north-south highway, winds for 105 mi (169 km) through the park. The Blue Ridge, Shenandoah valley, Massanutten Mt., and Allegheny Mts. can be viewed from 75 overlooks on the drive. Elevations in the park range from 595 ft (181 m) at Front Royal to 4,049 ft (1,234 m) at the top of Hawksbill Mt. Heavily forested, the park contains a series of ridges and valleys, hollows, small hills, numerous streams, waterfalls, and trout-filled pools. The Appalachian Trail follows the crest.
