From the D940 road from Etaples to Boulogne-sur-Mer, turn right onto the D148E6 towards Camiers. You'll soon find a car park on the right, the starting point for several hikes.
(S/E) From the car park, take the blue signposted path (GR®120) which winds through the woods and dunes (a few rises in elevation, good views of the Baie de la Canche and Le Touquet). Reach the D940.
(1) Cross the D940 with caution and take the path on the left hand side, which runs under a railroad line (orange markings).
(2) Continue due west on the path which, further on, veers to the left and joins the Étaples to Saint-Cécile path.
(3) You can cross a footbridge to reach the dunes and the Plage named "des Pauvres" (not signposted).
(4) To access the beach, retrace your steps back to point 3 and take the path that crosses the estuary marshes towards Étaples (lovely view over the Baie de la Canche).
(5) Fork left (GR® du littoral) northwards. At the end, turn right.
(2) Take the track that runs under the railroad to the 940 road.
(1) Follow the D940 to the left along the cycle path for about 50m. Find another path on the left and follow it (again marked in blue).
(6) Pass through a chestnut wood and return to the D940.
(7) Cross the D940 and, after a few hundred metres, turn left onto the D148E6, which will take you back to the car park (watch out for traffic) (S/E).
