A trail connecting Virginia's Northern Neck to history, nature, and recreation.

The 16-mile Dahlgren Railroad Heritage Trail follows the route of the 1940s Dahlgren Branch Rail Line, and stretches across King George County just south of the Potomac River in Virginia's Northern Neck. The trail is open for walking, running, cycling, and other non-motorized recreational uses. The trail is comprised of 240 acres of preserved sanctuary for native wildlife and natural beauty.
