Washington & Old Dominion Railroad Regional Park

The Washington & Old Dominion Railroad Regional Park, at just 100 feet wide, is sometimes called the “Skinniest Park in Virginia.” It’s also one of the longest—stretching the entire length of Fairfax County along the former roadbed of the W&OD Railroad. The park includes 45 miles of paved trail for walking, running, bicycling and skating and 32 miles of adjacent gravel trail for horseback riding. Par-course fitness stations and secondary trails can be found along the way.
