The starting point for the walk is at the junction of the D940 (the departmental road that follows the coast from Oye-Plage, near Calais, to Conchil-le-Temple just before the Baie de Somme) and Rue du Fort César. There are several car parks in the town of Wissant, the closest being Place du Marché, about 100 metres away.
By bus, take line 427 from Calais or Boulogne-sur-Mer and get off at the "Place du Maréchal Leclerc" stop. Walk 200 m north-east along the D940 to reach the starting point.
(S/E) Turn south-east. On your left, you will see a number of hiking signs indicating the GR®128, GR®145 and many other trails. Follow these signs. The road is paved but there is very little traffic. You will arrive at the intersection at the start of the loop.
(1) You can already see Mont de Couple in the distance, which will be your main destination. Continue straight ahead, following the GR®128 sign. You will arrive at the pretty Herlen farm, named after the small stream that flows right next to it.
(2) Leave the building on your left and turn left at the crossroads. You will then begin a climb between wheat fields on a stony path. You will arrive at a signpost.
(3) Turn right and follow the path marked "Les Hauts de Wissant"/GR®128/GR®145. The path continues to climb slightly. After 600 m, you will reach a paved road connecting the small villages of Hervelinghen and Audembert. Follow this road straight ahead for about 100 m.
(4) Turn left onto the GR®145 trail. You will then follow a partially stony path, slightly sloping with a gradient of about 10% for approximately 600 m. This is the most difficult part of the circuit, especially the last 100-150 metres, but it is still very doable. You will arrive at the highest point of the circuit: the Mont de Couple orientation table, which stands at 163 m.
(5) Continue south-east on a path that is half grass and half stony for just over a kilometre. You will be slightly less exposed to the wind on this part of the circuit.
(6) Leave the GR®145 trail and turn right to begin the descent of Mont du Couple (approximately 800 m at a 12.5% gradient). This section is very stony. You will rejoin the D249 in a bend between Leubringhen and Audembert.
(7) Skirt the road, follow the path and turn right. You will find yourself once again between fields with Mont de Couple on your right and the village of Audembert on your left. After 800 m, you will cross the paved road between Hervelinghen and Audembert again. Continue straight ahead for a little over a kilometre.
(8) Turn right and follow the path. You are still on a path between fields. After 400 m, you will pass a small wood on your right. Continue straight ahead for about 800 m.
(9) Turn right and walk for 400 m (still through fields) to reach the intersection at the start of the loop.
(1) Turn left and retrace your steps to return to the car park (S/E).
