Big Meadows Campground on Skyline Drive. The trail runs along stretches of the Blue Ridge Parkway and Shenandoah National Park/ Skyline Drive. You can get on at Front Royal (the northern terminus of Skyline Drive) or any of several access points to Skyline Drive that exist along the way many of which coincide with Appalachian trail access points or spurs. If you are just looking for hiking and camping, there are several trails along the drive near Big Meadows. Dark Hollow Falls and Stony Man trails are very nice. My Hub "Road Trip Memories" is about this area.
