Park in the Fort d'Ambleteuse car park on the beach.
(S/E) Take the GR®120 and follow the white and red markers. Walk north along the beach to the village of Audresselles.
(1) Here you have 2 options:
- at low tide, if you're careful, you can continue along the coast, leaping over the rocks,
- at high tide, you'll have to climb back into the village via charming little stone staircases.
Continue north through the village until you reach the rocky coast at Pointe du Nid de Corbet.
(2) Continue for a few hundred metres along the main road, then take the path on the left. Alternate slight ascents and descents along the cliff face. Reach Cran aux Œufs,
(3) Continue past Pointe du Riden, Cran Barbier, Cran des Silliers and Cran de Quette. Reach the entrance to the Cap Gris Nez site.
(4) Important note here: on the Cap Gris Nez site, the paths are fenced off and it is not possible to walk around them along the cliff to protect the site.
Take a few steps to the left to admire the view from the first lookout. Back at the crossroads, turn left to reach a crossroads with a central stone post at a car park.
(5) Turn left to make a small loop through the 2 lookouts. Back at the crossroads, turn left and pass between the blockhouses. Bend right and rejoin the GR®120.
(6) Turn right, due south, until you reach the D191.
(7) Leave the GR® here, turn left, then left again at the second junction with the D191. You'll come to a new crossroads, surrounded by blockhouses.
(8) Turn right onto the dirt track that leads straight on to La pointe à Chemise. Reach a crossroads.
(9) Turn left for a few metres and cross the road to the right. Continue along this road until you reach an imposing blockhouse in the Atlantic Wall museum.
(10) Keep to this path, bending left and then immediately right to reach the Haringzelles woods.
(11) Continue, then at the end of the wood, cross the D940 with care to take a small tarmac road which becomes a small paved road for bicycles. Resume on a new road.
(12) Turn right at right-angles into the village of Audresselles. Turn left into the main street. At the T, turn right and then left again, still on the main street. The last street on the right brings you back to the original crossroads.
(1) Continue in the opposite direction to the Vieux Fort Mahon car park (S/E).
