Car park of the multi-purpose hall, Rue de Fauquembergues in Coyecques.
(S/E) Go to the junction with the D 157. Cross it and follow it for a few metres on the left. Turn right into the first street (Impasse du Marais). Turn into the first street on the left (Rue de la Gare) and reach Rue de Bomy and follow it to the right.
(1) Cross the Lys at the three-way junction, turn right and 100 metres further on, turn right again into Rue du Crocq. Reach the hamlet.
(2) When you reach the block of houses, turn left onto the wide path. Follow it uphill for about 2 km until you reach a T-junction.
(3) Turn left. Ignore the path coming from the left and continue on the path which, a little further on, turns right at a right angle. It becomes wilder and turns right again to descend into the Lys Valley (probably a little damp at times?). Reach the junction with the D 104.
(4) Take the small road opposite. Ignore the road coming from the left and reach a T-junction (Capelle-sur-la-Lys). Turn left to arrive opposite a farm. Then take the beautiful path that branches off to the right. You will reach the Lys, which you cross via a beautiful footbridge, and arrive at the D 157 (Glein).
(5) Cross it carefully and follow it for a few metres to the right. Very soon, you can take a detour to the left. About a hundred metres further on, turn left to reach a fork.
(6) Turn right. You will immediately reach another fork. Turn left. Wide path, which then becomes grassy (and a little difficult in its upper part).
You will reach a T-junction.
(7) Take the wide, straight path on the left and you will reach another T-junction. Turn right onto the path that immediately branches off to the left at the edge of the woods.
You will reach a fork.
(8) Turn right and you will reach a three-way junction. Take the path furthest to the right (almost a hairpin bend).
Climb, gently at first, then more steeply to cross the Bois Quartier. At the edge of the woods, turn left to reach a T-junction.
(9) Turn right and reach the D 158. Cross it to take the wide path opposite, among the wind turbines. After crossing the Bois Cazier, you will reach a fork where you turn right onto a beautiful path that turns left and becomes wider. Ignore the path coming from the left and reach the entrance to Maisnil.
(10) Just before the first house, take the hairpin bend to the right (it feels like you are entering a farmyard). The entrance to the next path is closed by two gates used for livestock. They are easy to cross by passing through the bars (this is allowed!). You will then find a beautiful grassy path in the middle of the pastures and reach a T-junction (a place called Le Blikar).
(11) Turn right to descend into the Maisnil valley. When you reach the stream (there may not often be any water!), take the path opposite. It's a nice climb on a slightly slippery path, but it has been well restored. It then becomes wider. Continue along this path to descend to Coyecques and the Lys Valley. You will be joined on the left by the D 104 (Rue de Dohem).
(12) Continue straight ahead to reach a crossroads. Turn right into Grand Rue. At the next crossroads, turn left to arrive near the church. Before reaching the D 157, turn right to cross the square and, passing to the right of the church, join the car park of the multi-purpose hall, Rue de Fauquembergues (S/E).
