The Atlantic Wall trail at Carcans Plage

The Atlantic Wall (Atlantikwall in German) is an extensive system of coastal fortifications built by the Third Reich during the Second World War along the western coast of Europe to prevent an invasion of the continent by the Allies from Great Britain.

This walking trail follows the concrete road that served the blockhouses, which were used as forward posts.

(1) Continue straight ahead for about a hundred metres.

(2) Turn right onto theGR®8(red and white markings) towards the beach. Walk along the beach and then turn left.

(7) Stay on theGR®8and turn left (south-east). Cross a perpendicular path to reach the Maison Forestière de l'Alexandre.

(8) Retrace your steps to the previous crossroads.

(7) Turn left. Further on, at a fork, ignore the path that branches off to the left and continue south-west.

(9) At the information panel entitled "The advance of the blockhouses, the retreat of the coastline", continue towards the sea to see the blockhouses.

(10) Retrace your steps back to the crossroads.

If the tide is low, it is very pleasant to cross the dune and return via the beach. The time window for returning via the beach is approximately 3 hours before or after low tide.

A very beautiful, peaceful hike, except for the sound of cicadas 😉, and very easy. However, it is impossible to find the fork on the right at the beginning, and you end up at the foot of the dune with no sign of a path. You have to stay on the same track as the return path.

between point 2 (1st sign) and 3 (return to trail.
- The 2021 review already noted this (although there was an error in the GR number): "need to use the forest path that crosses from the first sign."
- The 2018 notice: "I was unable to find the detour that runs along a beach shortly after the trail starts; I followed the GR markings, which route this section."
- Your description: "(2) Turn right onto the GR®8 (red and white markings) towards the beach. Walk along the beach and then turn left. (3) At the crossroads, turn right and continue."

=> The red and white markings form a cross towards the dune (at your point 3) and if you go there anyway, you will find yourself facing the pine trees covered in sand from the dune. There is no longer a path. Only the "return" route (route 3 to 2) is possible.

Signs
The signs are not correctly positioned at the GPS points, as stated in reviews from 2018 and 2020
- "First themed sign (The Atlantic Wall)." => It is not at the car park, but rather towards (3), perhaps moved
- "Sign 6 is no longer visible from the path on the way there, unless you look back into the vegetation. What is visible is a strange wooden sign with a naive painting of an owl." => Incorrect location or sign moved

Hello,
Is the GR 8 the trail on the IGN map?

Hello, it's the GR8 that's covered, not the trail. Everything's fine. Love

Hello,
How is it not up to date? Explain yourself! There is no other route except to make a circular loop via the Alexandre forest house, but in terms of kilometres, it is no longer the same and the route would be different. There is no question of taking the beach route; just follow the indicated route and stick to it. Please do not change the route set out by the authors. If you decide to do otherwise, that is your problem, and in that case you should say that the route is not easy to follow. I would like to point out, however, that the path is far enough away from the dune to be covered with sand.

Very interesting hike along the beach, but the information is out of date. I created a new circular hike, correctly marking the points and removing the section of the trail that has since been completely covered by the dune.

Hello, regarding this route: the starting point is very poorly marked and no one could give us any information! We finally found it and started our walk. In terms of history, there really isn't much... the information on the trail description is very vague.
The route through the forest is pleasant.
I thought I would find historical remains in addition to the few signs along the way.
The Atlantic Wall? I'm quite disappointed.
I will try other excursions soon.
See you soon.

A very beautiful walk through pine forests with a few historical information boards to enhance the experience. However, the GR6 is impassable via the beach - you must use the forest path that crosses it from the first sign.

A beautiful walk along the edge of the woods, at the foot of the dunes, where you can admire the twisted pine trees that form the first barrier against the advancing sand. The long concrete path built by the Germans is also surprising!
If the weather and tide allow, return via the beach.
Thanks to the author.

- At the trailhead, I hesitated for quite a while, as I couldn't see the information panel on the Atlantic Wall, which was supposed to be "immediate". You actually have to walk 100 metres along the trail to find it... The mention of the tarmac cycle path was the key point that convinced me I was in the right place; I would add that the path starts in the middle of the south car park at Carcans-plage.
Sign 6 is no longer visible from the path on the way there, unless you look back into the vegetation. What is visible is a strange wooden sign with a naive painting of an owl.
This does not have much impact on orientation, as you quickly arrive at the "7" crossroads, which is impossible to miss.
I was unable to find the detour that runs along a beach shortly after the start of the trail; I followed the GR markings, which route this section.

A simple and pleasant walk, with well-designed information boards and a spectacular view of two overturned blockhouses at the foot of a dune on a completely deserted beach.

Easy hike. I returned via the beach for a change of scenery.
