The place were Stonewall Jackson earned his name, visit the sites of the first large battle (Bull Run/Manassas) between the eastern armies of the Union and Confederacy, overlaid with a second larger battle that allowed the Confederacy to invade Maryland (Antietam/Sharpsburg). Start at the main NPS building to see a 45 minute movie on the battle, tour the small museum, buy a few souvenirs, get information on any Ranger led tours, and the all important map of the two battles. You can now decide on whether you want to take the driving tour to the 14+ sites, or take a number of walking/hiking self tours and trails. The relatively short tour near the NPS building will give you a quick overview of the final stages of the battle.
