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 consists of flat water with some riffles and the scenery is mainly houses, unsightly commercial buildings, and an old power plant. There is a three-foot weir at a paper recycling plant below Mtn. Aetna Road and one short, rocky rapid beneath the Oak Ridge Road bridge at Funkstown allows you to finish with a splash.
