East of the Sillon de Talbert

Close to a natural curiosity that must be seen at high tide, known as the "Sillon de Talbert", this journey allows you to discover the history of seaweed with the CEVA (Centre for the Study and Promotion of Seaweed), enjoy the results of the work of shellfish farmers (oyster and mussel farmers) and learn how artichokes are obtained. This walk between sea and land, with no difficult terrain, can be enjoyed by all ages.

Description of the walk

The starting point is located in the car park at the beginning of the Sillon de Talbert.

GR®34marked in red and white

(S/E) Go down the few steps to head towards the "Maison du Sillon".

(1) Take the path on the left markedGR®34with red and white lines. At the end of the path, turn left to go down to the beach. After a good hundred metres, go back up to take a wide path. Continue along the path that runs along the coast to reach the viewpoint.

(2) Continue around the peninsula: pass by the Centre d'Etudes et de Valorisation des Algues (Centre for the Study and Promotion of Seaweed) and "Celtic Whisky & Cie".

(3) Continue north to reach Laneros.

(4) At the roundabout, turn left and then left again towards "Crec'h Gourdin". At high tide, this section ofthe GR® may be submerged: in this case, it is preferable to take the detour via the D33 road.

(5) Take the path on the left, leaving a house numbered 66bis on your right. 250 m further on, at the crossroads, turn left again.

(6) Take the path on the right that leads to a grove, then take the road on the left.

(7) Continue along the road on the left, still following the red and whiteGR®34markings.

(8) When you reach the farm on the right, take a shaded path on the left, bordered by a dry stone wall. At the end of the path, turn left.

GR®34marked in red and white. +PR® marked in yellow

(9) Back near the coast, turn right following the sign for "Route des Trois Chapelles" (Three Chapelles Trail). After walking alongside a field on one side, take the path leading to it and turn left towards the beach. Take the stairs on the right to reach the Bonne Nouvelle Chapel. The path crosses two paths leading down to the beach at right angles and ends on the beach (be careful at high tide, as there is a risk of flooding). The path leads to the oyster farms. Go down to the shore and take the steps on the right. At the end of the steps, leave the road on the right and go straight on along the path that runs alongside a field. This path ends at a road, which you take on the left towards Porz-Guyon.

(10) In Porz-Guyon, leave theGR®34by turning right onto a road (about 600 m) to reach the D20 departmental road, which you take by turning right to arrive in the village of Lanmodez.

(11) Cross the village until you reach the road on the left before the church and just in front of the town hall. Take this road towards Croaz Guen. At a left-hand bend, take the path on the right that runs parallel to the road. At the end of this path, you will find yourself in front of a ruined house.

(12) Turn right, then at the next crossroads take the path slightly to the left and you will reach a crossroads at Tos Crec'h, between a garage and a house.

(13) Turn left. At the end of the path, turn right and then right again onto the road that joins the D20. Take the D20 to the right for about 200 metres until you reach a crossroads.

(14) Turn left onto Rue de Porz Rand until you reach the riverbank and rejoin theGR®34.

(15) Turn right and follow theGR®34back to the Talbert gully and your starting point. (S/E)

Fortunately, much of this route follows a wild and rugged coastline, alternating between rocky shores, iodine-rich seaweed deposits on beaches and shorelines, coastal marshes, pebble dunes and foreshores stretching as far as the eye can see. These offer an ever-changing spectacle with the tide. The rest of the route, mainly on small roads, is not particularly interesting, but we have to get back. We are on a peninsula, described as "wild" and well preserved, which is not an island, so the sea must eventually leave us. The app's GPS is very useful for avoiding getting too lost.

I have to mention the signposting because it was inadequate in the village of Pleubian. We had to ask some locals for help. They told us we weren't the first to get lost in this area.
Otherwise, it was a pleasant route, except for the right-hand side where it was difficult to find your way.
Thank you.

Route completed in January. No crowds.
very beautiful route between points 1 to 11, then 16 to 1. Between 11 and 16, a lot of road.
Note that between 12 and 13, I couldn't find the indicated path, so I took a detour with the help of the map displayed by Visorando on my phone.
Note: I started from Port Guyon to begin on land/road and finish by the sea.
Also note: it is possible to do the Talbert channel as well, depending on the tide times.

We only did part of this route but added the return trip on the Talbert Ridge.
A very beautiful place.

HIKE done at low tide (not very interesting 😥) route and signposting are average, some sections are no longer accessible. A bit too many roads. Quite disappointed.

Hike done at low tide, the tidal range is very impressive, you can no longer see the sea from certain places.
The section from WP 16-1 to 10 on the coast is the most spectacular.

Hello
Very beautiful hike; beautiful circular "land/sea".
However, we preferred to take the PR path marked in red between Porz Guyou and Lanmodez, which is further north and can be accessed at the entrance to the village of Porz Guyon, to avoid the main road!
Enjoy your hike

picturesque hike. It is sometimes difficult to walk on the pebbles, so wait for the tide to go out to reach the sand.

Along the coastline, there are beautiful views of the reserve and the marshes.
However, some sections are inaccessible due to large private properties.
