The 100-foot-wide Washington & Old Dominion Railroad Regional Park (W&OD Trail) features a 45-mile asphalt trail for walking, running, bicycling and other activities and a 30.5-mile, parallel, gravel bridle path for horseback riding and hiking. The W&OD Trail is managed by the Northern Virginia Regional Parks Authority and more detailed information can be found here.
Stretching from the Potomac River, near Washington, D.C., to the Blue Ridge Mountains, the W&OD is a recreation corridor extending from Virginia's suburbs of Arlington to Purcellville in western Loudoun County.
The W&OD Trail takes its name from the railroad whose trains ran along the right-of-way from 1859 until 1968. Never very successful, the railroad's demise was hastened by the improved road system and increased number of motor vehicles.
Scenery along the W&OD is like that from a train window--changing from county to suburbia to city.
Local hikers and cyclists may want to plan a series of day trips to explore different sections of this linear park with its varied attractions. History, nature, community and recreational opportunities are endless!
