Mount Vernon Estate to Key Bridge
Beginning at the steps of Mount Vernon Estate, this hike follows the Potomac River and the George Washington Memorial Parkway on the Mount Vernon Trail. More than 20 bridges are crossed, including two more than 1000 feet across vast marshlands. Near the 10-mile mark, the route passes through Old Town Alexandria on sidewalks. The entire trail is paved, but, except for a few segments, bicycle traffic is generally moderate. A number of side trails lead to historic sites along the way. An added bonus is that both ends of the section are served by public transportation and the National Airport Metro station is right on the trail five miles south of Key Bridge.
