This walk will take you along Difficult Run between Colvin Run Road and Leigh
Mill Road. This is a part of the Fairfax Cross County Trail. The trail is
in good condition except for one very short sunny section where the brush
slightly overhangs the trail. You may wish to be alert for ticks in this section.
This is not a loop trail so the mileage has been doubled to reflect the need
to return to the starting point. The directions have been written to cover
walking in either direction on the trail and pictures are shown in both directions.
The best starting point is from the parking area adjacent to the pumping
station on an access road leading from Colvin Run Road at its intersection
with Route 7 and Carpers Farm Way. There is a traffic signal at this intersection.
From Reston turn left at the traffic signal on Route 7 and immediately turn
right onto the access road. Follow the links and pictures marked east to walk
- (East) The trail starts from the center of the eastern end of the
parking lot. This is a gravel trail at this point. Do not take the trail
to the right or south of the parking lot as it follows Difficult Run in
the opposite direction.
(West) This portion of the trail ends at the parking area adjacent
to the pumping station. From here you can continue along Difficult Run on
the Cross County Trail or take the Colvin

- (East) There is a Cross County Trail marker about 90 feet after
the gravel surface of the trail ends. Turn right to follow the natural surface
trail up the hill away from Difficult Run. You are leaving the horse trail
as it continues to follow Difficult Run. The horse trail becomes quite muddy
in places after this point (see pictures) but
is negotiable with some care.

horse trail. The trail has a gravel surface after about 90 feet from that

through the woods and homes can be seen on the right. The trail turns left
and passes through a very short sunny section. The trail turns right and
continues through the woods.

with some brush overhanging the trail. The path continues through the woods
and turns right with houses on the left.
- (East) The trail enters the circle at the end of Brian Jac Lane.
Turn left and walk along the grass along the other side of the private driveway
to find the marker for the trail only a few feet from the circle. The trail
turns left as it enters the woods, then makes a sharp right to continue
down the hill.
(West) The trail exits the woods adjacent to a private driveway.
Turn left and walk a few feet to the circle at the end of Brian Jac Lane.

the combined horse/Cross County Trail.

trail route at this location.
(West) At the end of the meadow the trail enters the woods.
- (East) The trail intersects with Leigh Mill Road next to a one
way bridge over Difficult Run. The Cross County Trail continues on the other
side of Leigh Mill Road headed towards the Potomac River. Return to the
starting point of this walk over the route that was just walked.
(West) The trail follows the cleared area of the meadow parallel
to Difficult Run on the right.
