If you just go to the visitors center, you truly miss out on all there is to see at Manassas. There are two great hikes; one for the First Battle of Manassas and one for the Second Battle. When I visited back in November, I only had time to do one of the hikes and opted for the First Battle trail (it is the shorter of the two). It was a cold day, so I kept a brisk pace. It was nice to get out and see the battlefield and place of historic significance were well marked with information placards. I think I learned more about the battle by doing the hike than I ever did in High School History (also learned why it is also called Bull Run). I hope to go back soon and do the Second Battle Trail and learn what happened then.
