The starting point is at the following address: 4, Chemin de Bomy, Thérouanne. Parking spaces available.
(S/E) From the starting sign, head up the hill. At the junction, carry straight on to reach the hamlet of Les Cornailles.
(1) At the fork in the road, turn left and carry on straight ahead until you reach the sign explaining the three battles that took place at Enguinegatte.
(2) Turn left and head up the hill, passing several junctions. Once at the top, turn right, ignore a path on the left and walk past the pumping station. Turn left, reach the main road and cross it at the pedestrian crossing. Then turn left until you reach the nearby crossroads (small car park).
(3) Turn right onto Rue Longue and continue to the junction.
(4) Turn left and follow the path downhill to reach the departmental road at the end of Chemin du Milieu, at No. 41.
(5) Turn left. At the junction, go straight on, and do the same at the Stop sign.
(6) After the bank and in front of the veterinary clinic, turn left onto Rue de Nielles to return to the starting point (S/E).
A lovely walk with no trouble finding my way; I only followed the .gpx route when in doubt.
