(S/E) Leaving Delettes, we head towards Upen-d’Amont, leaving the departmental road for a country lane where a steep climb awaits us. We then turn left towards Dohem, then on to Maisnil via a country lane.

(3) At the second junction, we turn left towards Enguinegatte.
(4) After passing through the village, a small country lane on the left takes us back to Nielles-les-Thérouanne.
