Seneca Regional Park

Beautiful wilderness and winding paths await at Seneca Regional Park. Located on the Fairfax/Loudoun County line and along the Potomac River, Seneca offers a great network of trails. The park is also bisected by the Potomac Heritage Trail that extends from Loudoun County, through the Seneca Tract, to Riverbend Park, and further south to Great Falls where it connects with the Fairfax Cross County Trail.
