Start from the large car park opposite Enquin town hall on the D158.
(S/E) Follow the D158 towards Erny-Saint-Julien. At the first crossroads, turn right onto Rue de la Brasserie. Drive down to the Lacquette, cross it and turn left.
(1) Under the church and opposite the beautiful Spanish mill, cross the Lacquette again (footbridge or ford for enthusiasts) and reach the D158 opposite the calvary. Turn right into Rue du Calvaire. At the fork, turn right onto a grassy path and join the D77. Follow it to the left for 300m.
...(2) Take the right-hand path to reach a T-junction. Turn left and, a few metres further on, right to climb Mont de Cuhem.
(3) At the edge of the Bois des Moines, take the path on the left with the GR®127 (white and red markings). This is a beautiful downhill path, unfortunately regularly massacred by quadbikes and other "green" motorcycles (excellent on August 15, 2020).
Keeping the same direction, reach the tarmac. Turn right to reach Cuhem and the D159.
(4) In the village, follow the GR®127 signs. Follow the D159 to the right, reach the church and turn left immediately. Follow the cemetery, then turn left at the first crossroads to join the D77 (route de Saint-Omer).
(5) Follow this for 100m, then turn right onto the D159.
(6) At the fork, turn right and climb Mont Roger (small asphalt road). Stay on this small road until you reach the fork at the summit (elevation 112).
(7) Leave the GR® and turn right down to Fléchin.
(8) Shortly before reaching Fléchin, don't miss the upward path on the left (GR®). At the crossroads, go straight ahead for 1km.
(9) At the antenna, turn left towards Ferme de la Carnoye (path sometimes damaged). Before reaching the farm, turn right onto the tarmac and 100m further on, turn left.
(10) In the right-hand bend, leave the tarmac to take a path leading down to Fléchinelle (still GR®).
Reach the D159, follow it to the right and immediately turn left. Cross the Surgeon, and turn right on a good path that takes you up to Enquin-les-Mines.
(11) Shortly before the D158, at a hiking pole, turn left. Shortly afterwards, turn right through the beautiful new buildings of Enquin, to reach the car park.(S/E)
