Antietam National Battlefield

This 960-acre battlefield, often taken in by car, was the site of the single bloodiest day of warfare in American history. More than 23,000 soldiers were killed or wounded as the Confederate Army, flush with victory at Manassas, tried to penetrate the capital's defenses from the north. You can view a 30-minute film about the battle at the small museum and visitor's center.

Highlights include:
Burnside Bridge, a structure depicted in many war paintings, and Bloody Lane, where many soldiers died. In early December, there's a beautiful and moving illumination, as the roads of the driving tour are lined with candles.

-- John Kelly and Craig Stoltz

Words to the wise: Unlike Manassas, this battlefield isn't as accommodating to exploration on foot.
