Description of the walk

Parking is available opposite Grand Large Beach or along the Pointe de Mousterlin cliff road.

(S/E) With your back to the Grand Large beach, follow the path that runs alongside the marsh (information board).

GR® 34 White and Red + Orange markings
Turn right, pass the campsite entrance and follow the wide path that runs alongside the pastureland.

Blue markings

(1) Leave the GR® and the orange markings, which turn right onto a dyke, and continue straight ahead. The path continues along a small road. At the junction with another road, at the signpost marked "Balade autour de Mousterlin" (Walk around Mousterlin), turn right and then right again to follow a small road between wetlands.

(2) At the signpost marked "variante" (alternative route), turn right and follow this path along the edge of the marsh. It forms a circular loop and joins a small road, which you take to the right.

(3) Follow the path on the right, which joins the dyke that we left earlier.

GR® 34 White and Red markings
Go around another campsite, leave the road leading to the Cleut Rouz beach car park on your right and continue with the marsh on your right.

No real markings
(4) Leave the GR® and turn left. Follow this path, which joins a wide track, and turn right to arrive opposite the entrance to another campsite.

Blue and red markings

(5) At the sign for the Kerbader Chapel, turn left, follow the hedge bordering the campsite and you will reach the grassy esplanade of the chapel with a large restored bread oven on your left.

(6) Continue following the sign for the fountain, pass behind the Manoir de Coat Conan and then turn left to reach the fountain in the middle of a meadow.

(7) Retrace your steps back to the road.

Blue markings
Leave the red markings on your left and continue straight ahead on the path (signposted "Renouveau 600 m"). The path leads to a barrier and directional signs.

No real markings
(8) Turn left onto a small road, leaving the sign for "Renouveau 200 m" on your right, and continue past a small house and its blue gate. This small road winds and at the three-way junction, follow the road that turns right. Leave the access to Penfalud on your left, then the next road.

(9) At the dead end sign, turn right then veer left at the entrance to the Kerodé farm. Go through the gate and follow this path lined with pastureland.

GR® 34 White and Red + Orange markings
(10) Find the trail markers from the start and head towards the former Renouveau holiday village with its distinctive architecture. Pass the beach access point and continue along the wide path, still skirting the marshland. Continue to the boardwalk that crosses the marsh.

(11) Turn right to cross the marsh and leave the GR®38 trail continuing north-east.
Orange markings

(12) At the end of the boardwalk, you have two options for returning to the car park, heading due west: follow a wide path covered with mulch that runs alongside the marsh (the route) or, depending on the tide, go via the beach.
Whichever option you choose, it is entirely possible to switch from one route to the other.

(13) Over an area of approximately 300 metres, a sandy passage lined with wooden fences has been created. This passage through the sand is particularly tiring.

 (14) At the Cleut Rouz Beach blockhouse, climb to the left to continue on the path at the top of the rockfill, which offers a beautiful view of the sea. This will take you to the car park (S/E).

Notes

Toilets are available at the car park at the start of the route, at the beach near the Renouveau holiday village and at the car park in Cleut Rouz. The route is classified as moderate in terms of distance but can be considered easy as it is completely flat.
The route may seem complicated due to the interference of numerous markings, but the paths are easy to follow on the ground. However, be sure to refer to the description and the Visorando map, as the route juggles between different possible routes.

There are many opportunities to shorten this route.
This is a scenic route to be enjoyed in spring and before the summer crowds arrive, or later in autumn. In winter, some sections near the marsh may be impassable.

I was worried that the inland section would detract somewhat from the appeal of this hike. But that wasn't the case at all. Whether along the shore or in the vegetation inland, everything is beautiful to see. The route is perfect.

Beautiful hike, very well marked. There are lots of bikes on most of the hike, a sort of motorway... Don't hesitate to take little circulars in the marsh. Thank you for this family hike...

We had a few minor hesitations at times, but overall, the route is fairly well documented. It's a beautiful walk with sections near dunes, beaches and marshes, plus a chapel, church and futuristic 1970s holiday centre. Refreshments are available at the start/finish point. The ground is very spongy on the way to the fountain.

Pretty fountain in Kerbader, beautiful discovery of the marshes and pleasant walk on the beach. We shortened the route between (8) and (10) to have time to add a return trip to the Pointe de Beg Meil to this itinerary.
Thank you, Michel, for this walk idea.

We had no trouble following the trail. In June, the route wasn't in bloom, but we timed it perfectly with the tide so we could return along the beach with our feet in the water, and it was simply divine!!!

Easy hike. Sometimes a bit of a treasure hunt, but that adds to the fun. The first part introduces you to the tourist facilities that respect the area, despite the numerous large campsites that remain discreet. The return trip via the beach with a swim is very pleasant.

Thank you, Monique C3

I think there was a mistake in reading the description.
I had written:
"(7) Turn left onto a small road, passing the sign for "Renouveau 200m" on your right, and continue past a small house with a blue gate. This small road winds and at the three-way junction, follow the road that turns right. Pass the entrance to Penfalud on your left, then the next road."

It's no big deal.

Best regards.

Hi, at number 7: you have to follow the CR72 Atlantique sign, not the Renouveau sign. Have a good day.

Hello, nice hike, but we got lost at the Renouveau holiday village. The directions were a bit vague!
