Start: Aumerval church.
(S/E) Take the D91 towards Ferfay (GR®127 and GRP°® Tour du Ternois Nord). After 400m, turn right onto the wide track (still GR®). After a 90° right-hand bend, ignore a track on the left and continue straight ahead on the grassy path. Pass the cemetery and reach the D90.
(1) Stay on the GR®, go straight ahead (slightly left) and climb towards the wood. Continue through it (difficult in wet weather), keeping south-west. Join a small tarmac road.
(2) Follow it a few metres to the left, this is the Chemin du Bois, then turn right onto the wide Chemin du Bois de la Paroye, first through undergrowth, then between fields to join the GR®127 and the GRP°®.
(3) Turn right along this path. Follow this beautiful path along the Clarence river to Sachin. At the 1st crossroads (chapel), turn right onto the Grand Rue towards the church. Ignore the street to the right, pass the church, then the school, and reach the Rue du Buich crossroads.
(4) Just before Rue du Buich, take the path on the right, then go immediately right (turnstile). A beautiful path climbs, then descends again (new turnstile) to a farm. Continue straight ahead towards the chapel (very muddy in wet weather, but the bottom is stony). Go through the gate and reach the chapel.
(5) Turn left into Rue des Fonds. Ignore the 2 successive left-hand paths to reach a new crossroads.
(6) Take the left-hand path alongside Bois Fontaine. Turn right at 90° to reach a new T-junction.
(7) Take the left-hand track. At the next junction, turn right onto the grassy path to reach the edge of the wood.
(8) Go straight ahead at the edge of the wood. This path (signposted for mountain bikes in the other direction) follows the edge before entering the wood and rejoining the D77. Caution: huge ruts (which wild boars seem to appreciate!!). Be sure to follow the barbed wire on the right and from time to time take a good grassy path on the left (not forgetting to return to the original path from time to time) or the paths on the right that go around the waterholes (very difficult passage in October 2024)
(9) Follow the D77 to the right for a few meters, then go right through the woods (reverse Pignolet and VTT). A good path, sometimes damp, veers left before reaching a forest house.
(10) Turn right, then immediately left to go down to the D90: fine views as far as the Monts de Flandre. Cross the D90 to take a wide track opposite. It bends left at 90°. Further on, turn right to pass the gas station and reach a T junction.
(11) Turn right. Turn left 100m further on the GR®127 towards Amettes. At the T junction, turn right to reach the square (Maison de Saint-Benoit on the left).
(12) Go through the square and round the church to the right: lovely park with wooden statue. At the tarmac, turn right, ignoring the left-hand street, and head downhill towards La Coqueline, reaching a calvary.
(13) Turn right (yellow-marked Coqueline country path). A wide, slightly uphill path reaches a fork. Turn right to reach Fond de Dinghem. Cross the Coqueline (ford or footbridge slightly hidden on the left). Follow the Coqueline to reach Bailleul-les-Pernes. Beautifully restored path.
(14) At the tarmac, go left, cross the Coqueline, ignore the road to the right and climb to reach the D90 (calvary). Follow this for a few metres, then turn left onto the GR® (signpost with arrows). Climb up to the edge of the field and reach T. Turn left to reach the church and square (S/E).
