In Erquinghem-le-Sec, parking is available opposite the town hall or church. Parking is also available perpendicular to the D7 road at the entrance to the village from Lille via Englos and the D7.
(S/E) To reach the start of the route, take the D7.
(1) Take the path alongside the children's playground at the entrance to the village, perpendicular to the D7. The path quickly leads to a street that crosses a housing estate. Turn right at the end of the cul-de-sac. A path (not very visible) runs between two gardens and leads to an outdoor sports complex. Take the gravel path between the soccer pitch and a large hedge.
Cross the D141b at right-angles to enter the dirt track on the site of an old railway line. Follow this for about 1km. Reach the Becque stream.
(2) Take the steep downhill path on the left. You'll come to the back of a water treatment plant. Pass between the ditch on the left and the plant's fence on the right (the path exists but is not very well maintained, and can sometimes be difficult to see). Come to the D141, follow it to the left for about 100m. Leave the road and turn left, continuing straight on past "Le Maresquel".
You will then come to a tarmac road.
(3) Turn left onto "Rue des Aubeaux". Follow it to join the D62 (at Radinghem), turning right, then taking the second left.
(4) Follow the road (right, left), past "Martin Camp". Follow the asphalt road (left and right 3 times). When you reach the other road, there's a T-junction.
(5) Turn left towards the village of "Le Maisnil", passing an oratory. Go straight through the village, past the church, and cross the D141b at the traffic lights.
Immediately after leaving the village, follow the paved road straight ahead (leave the road on the right). Continue along this paved road until you reach the D7.
(6) Cross the road and go straight on towards the hamlet of "Desprez". In the hamlet, turn left onto the small road and left again at the end onto the dirt track. Follow to the Beaucamps-Ligny traffic circle.
Cross to the left (towards Beaucamps) in the direction of traffic. Then, just after it, and before the oratory, turn right onto the gravel path that runs behind a house.
Follow it through the hamlet of "Haut-Brule". The paved road crosses the old railway line.
(8) Leave the paved road, and turn left onto the dirt track of this old railway. Return along this track to Erquinghem-le-Sec, join the loop crossroads.
(1) Continue on the outward route to the car park (S/E)
