Hills and valleys in Coyecques

From the Lys Valley to Noir Mont and discovery of the hidden valley of Maisnil.

The route is almost entirely off-road, either on good grassy paths or vaguely paved paths.

Do not look for markings, as there are none.

Description of the walk

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).

A truly beautiful hike, Mr Joorange! Thank you!
Very little tarmac, a wide variety of paths and landscapes.
No difficulty, the paths are clear and almost dry everywhere!
The countryside is beautiful in spring: the yellow of the rapeseed fields, the ochre of the poplars with their buds bursting open, pheasants, hares...
Pure bliss!

Good news, the path between 11 and 12 has been very well cleared (November 2022).
It is still difficult because it is very slippery (I walked down it yesterday: with the barbed wire on the side, it's "fun").

Small change after point 6.

Superb hike over hill and dale.
Impeccable description!
You'll need more than just secateurs for the final climb after the Maisnil valley! (over 200 metres)
Some short sections may be difficult in wet weather.
Excellent!

A very beautiful route alternating between small country roads, trails, woods, rivers and even pastures! All this with elevation changes and beautiful scenery!
I didn't see a single person for 15 kilometres! (What bliss!)

So I went to the area this morning, starting from Avroult.

The recent rains have already damaged the wide path leading to Les Bohons. There is a huge puddle there, which I bypassed by walking through the fields (I raised my stick high, but the waves did not part... There must be a trick to it!).
The next path to Maisnil is in perfect condition and pleasant.
The path to the sewage treatment plant is very rural, but the barbed wire, especially on the way out, is quite difficult to get through! (especially for someone on their own).
The passage along the edge of the woods was quite tiring this morning (slippery ground). I saw that there was a very nice path through the woods, but it was closed by a barrier (as is often the case).
I then continued through the Maisnil Valley to reach Le Capillon: a nice climb along the cornfield!
Then, I took the normal path to point 11. I took the opportunity to locate the zigzag path that crosses the Blikar. It's a wide farm track (a bit dirty at the start) that leads to the edge of the woods. It's less wild than the one at the sewage treatment plant, but it has the advantage of not having any barbed wire.

In short, a superb morning that will allow me to sleep in front of the telly tonight.

Thanks again for sharing.

Hello,
For the extension of this hike, I followed points 1 to 9 from the start, then on to 10. At Bois Casier, altitude 120m, take the path on the left towards D133 (Terres à Charbon); follow D133 for 150m, then take the path on the right towards Les Bohons. Cross the D190 and take the path on the left towards Maisnil. At the road, turn right, then right again, then left towards point 11. Before a shed on the left (altitude 134 m), take the path that descends towards the water treatment plant. You will come to a pasture, which you cross (2 barbed wire fences), then follow the edge of a cultivated field to join the road that leads to Fond de Maisnil. Walk up along the woods on the right-hand side of the field to reach the path that leads to Le Blikar. Head to point 11 on the right, then point 10. Then, heading towards point 9, at Terre Peuchon, walk down the field to reach Le Capillon and the Maisnil Valley path. At the T-junction, turn right towards point 12 and the finish.
Enjoy your walk.
Michel

Sorry, I got confused.
Which is a bit embarrassing for a hiker!

Another superb hike with paths that are passable even in wet weather. We extended this hike to 22 km, staying true to the original idea of the discoverer (we only removed 500 metres).

A beautiful hike mainly on paths, with a few hills and wooded sections.
It's perfect!
