Antietam Creek is born just north of the Mason-Dixon Line and winds and twists for almost 41 miles to the Potomac River. This scenic country creek has long been a favorite for novice whitewater paddlers. This section of Antietam twists and turns through attractive farm country that is complemented by the normal array of big, decorated barns and sturdy, old farm-houses. The narrow stream is always fairly swift, and there are plenty of riffles. There is a scrapey dam to carry about two miles below Old Forge Road and another weir located at the take-out which requires a portage. This route is runnable spring and winter within a week of moderate rain.
