The Shenandoah River meets the Potomac River at this small West Virginia town that was the site of abolitionist John Brown’s raid on the United States arsenal in 1859, an event that hastened the onset of the Civil War. The extremely affordable city sits in the middle of the Appalachian Trail and offers both casual nature-lovers and die-hard sportsmen hiking, fishing and whitewater rafting opportunities.
