The NPS offers a Ranger led program that takes you down 2 miles of the A.T. I would highly suggest this tour. If you don't know anything about the trail, you will when you are done. The trail has great history and it very interesting to learn about it. While we only did about 5 miles of the trail in total on the whole trip, the story told by Ranger Woody was great and gave us a wonderful perspective of what people have to do to complete the 2000+ mile journey. As an fyi...many of the Shenandoah NP trails cross the AT.... We were told that the people who hike it end to end love it when they come to Shenandoah....you'll see why!!! Give it a try.
