The Bloodiest One Day Battle in American History 23,000 soldiers were killed, wounded or missing after twelve hours of savage combat on September 17, 1862. The Battle of Antietam ended the Confederate Army of Northern Virginia's first invasion into the North and led to Abraham Lincoln's issuance of the preliminary Emancipation Proclamation. Park Grounds are open daylight hours.

I love Antietam because of the history and the fact that you can literally wander off into complete solitude rather quickly. Just be respectful of private property.

Interesting hike. A variety of trail types ranging from mowed grass paths circumventing cornfields to dirt roads. Is a hike I would do again- so much history! We really enjoyed it. It is long, but not rigorous. We brought our dog Jip along and he did well.

love the history of this place. good in the car, by bike, or by foot. you really get a sense that your walking through history

Beautiful array and variety of wildflowers!

As of August 2016, the Burnside Bridge at the southern end of the trail loop is closed for repairs. The closure began in October 2015. Press reports say that the bridge will reopen in the fall of 2016, but check on the status of the bridge at the visitor center before setting out.
