When I saw Shenandoah Park for the first time, the song "Oh Shenandoah" came to mind. It is absolutely breathtaking. Make sure that you plan several hours or even days to appreciate this natural beauty.
There is so much to do here. Before planning your visit, go to http://www.nps.gov/shen/pphtml/planyourvisit.html. We enjoyed stopping along the way and taking a few short hikes along the Appalachian Trail system.
In addition, be sure to watch for deer! We saw deer everywhere. Be cautious as they are quite tame, and are very curious. Unfortunately, people have started feeding them over the years. We had a couple come right over to our car window and want us to feed them.
