Departure: Plage du Royau car park (alternative spelling: "Royo").
(S/E) Head north-east at the end of the car park and take the Sentier des Douaniers. It runs along the coast and ends at Rue des Dunes. First turn left, then right after 20 metres and rejoin the Sentier des Douaniers. Continue along the path until it ends at Rue de Roc'h Lahz. You will arrive at Port-Blanc via Boulevard de la Mer.
(1) Offshore, you can see Île des Femmes. Continue along Boulevard de la Mer until you reach the Oratory; on your left, you will see a small granite building flanked by a cross on top of a rock. After the Oratory, take the first street on the left (on your left, there is a sign saying "Le Rocher du Voleur"). Continue to the port.
(2) From the port of Port-Blanc, you can admire Île Saint-Gildas with its buildings and, in particular, its chapel. Continue along this road. At the crossroads, continue straight on along Rue Edouard Donzelot, then turn right into Rue de la Sentinelle and left into Impasse de la Chapelle. Cross the chapel grounds and turn left when you exit. The path becomes a road as it crosses the housing estate. The street ends at Rue de Roc'h Gwen, which you take on the left and then immediately turn right.
(3) Take the path on the left. After a little over 200 metres, turn right onto the path, which becomes a street and leads to a crossroads. Turn left, then take the first street on the right, then left onto Impasse Poul Gleisker.
(4) The cul-de-sac leads to Rue du Launay, which you take by turning left. Turn left again onto Rue de Poulpry until you reach Route de la Corniche. Continue for just 50 metres and take a path on the left. When it becomes a road, follow the second path on the right and continue along the road on the left. At the calvary, continue on the right.
(5) Take the path on the left until you reach the road, which you take on the right, then left at the first street. After 70 metres, it becomes a connecting path and then Rue Chemin de Traou Woas again. You will arrive at a place called Kergall.
(6) Cross the first road, continuing straight ahead along a cross path to reach Route de Tréguier, which you cross, continuing straight ahead. Continue straight ahead at the crossroads, cross Rue de Saint Guénolé, then turn right onto Rue de Bel-Air and take a path on the left. Continue along the road via Rue du Moulin.
(7) Take the path on the right towards the Trestel marshes. Cross the river over the small bridge and continue along the path.
(8) Before a bend on the left, turn onto a small path on the right. Walk through a wooded landscape and, after a steep climb, you will come to a road.
(9) Take the stairs that end on Route de Trestel. Continue downhill to the coastal road. If the tide is low, walk down to the beach. Walk alongside the rehabilitation centre. Leave the beach by climbing up the slipway and continue straight ahead. Otherwise, continue along the road, turn left into the centre's grounds and walk to the top of the slipway.
(10) Turn right onto Rue de Poulpry, then turn left twice. The street turns into a path that runs along the sea to the car park where you started (S/E).
