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).
