The 16-mile Dahlgren Railroad Heritage Trail follows the route of the old Dahlgren Branch line, stretching across Virginia’s King George County just south of the Potomac River. The trail is open for walking, running, cycling and other recreational non-motorized uses while preserving 240 acres of wildlife and natural beauty. The Dahlgren Trail has been designated a National Recreation Trail and a part of the developing Potomac Heritage National Scenic Trail network, which stretches from the mouth of the Potomac River at the Chesapeake Bay to the Allegheny highlands of Pennsylvania.
The trail’s natural surface varies from leveled sections with stone dust to uneven dirt sections with roots. Consult the trail map for more details on trail conditions and parking/access information.
The trail opened in 2006 as a privately owned recreational facility accessible by permit. Approximately 2,700 users and their families have received free trail use permits to date.
