Car park at the entrance to Penbron Point, on the border between the woods and the salt marshes.
(S/E) Leaving the car park, turn left towards the marshes and follow the road to Pont de Lancly. The etier (canal supplying the marshes) that passes underneath provides water to all the marshes on the left side of the road.
(1) Once you have crossed the bridge, immediately turn right onto the path that goes around Lancly Island. It is not strictly speaking an island, but the area is almost entirely surrounded by salt marshes, giving it an island-like appearance. Follow the path that runs along the boundary between the land and the marsh to rejoin the road you just left. 150 metres before you reach it, turn left; the path that continues along the marsh is a dead end.
(2) At the road, continue to the right until you reach "Chez P'tite Casquette". All that remains of the original beach hut is the sign bearing the image of the first owner, who made his fortune by grilling sardines over vine shoots.
At the crossroads, turn right and follow the RD92 for about 300 metres. Be careful, the road is narrow and very busy on sunny days. Before the first bend, take the path on the left towards the Moulin de Trévaly.
(3) When you reach the hamlet, turn left and walk past the mill. You will be treated to a sweeping view of the marsh and the Traict de Pen Bron. In summer, when the mulons (piles of salt) grow larger on the marsh, the landscape is dotted with as many white dots as there are mulons, which have made the Pays Blanc so wealthy.
After the mill, continue along the path that curves sharply to the left (ignore the paths on the right) and leads to the hamlet of Trévaly.
(4) At the farm, turn left and walk down the road towards the marsh and the RD92. On your right, hidden by the trees, you can sometimes see the charming Trévaly manor house.
(5) When you reach the district road, turn right. Follow it carefully for one kilometre.
(6) Turn left just before the first salt shed you come to as you leave the marsh. A path winds its way between salt ponds and the edge of the woods until it reaches the beach car park. Walk up this car park to return to the road.
(7) Cross the road connecting La Turballe to Pointe de Pen Bron and enter the woods, leaving the campsite entrance on your right. Turn left onto the path through the pine forest, some distance from the campsite fence, then when you reach the south-west corner of the campsite, turn right at the corner to go up the path that follows the fence and continue straight on to Penbron beach.
(8) When you reach the beach, go down and follow the foreshore for about 350 metres, passing at the foot of the white pyramid (landmark) overlooking the dune. Climb back up the dune at the first access point you find to return to the pine forest. Beyond the white pyramid, the beach is naturist. To avoid this area, simply follow the path along the top of the dune. Although it is more difficult to walk in loose sand, the views of the beach are reduced.
(9) Follow the fence that separates part of the Pen Bron woods, go around it on the left when it branches off to the right, and return to the car park at the start via a wide path through the pine forest (S/E).
