Description of the walk

_ Start_: From the car park of Port Blanc chapel (harbor).

(S/E) At the top of the steps, you can see the chapel, but we'll find it later. At the far end of the car park,
a pedestrian alley (Chemin de la Chapelle) invites you to explore the houses.
At the end of the alley, turn into Rue Saint-Gildas. Turn left at the crossroads with Rue de Crec'h Morvan (you'll see a wash-house in front of you). Turn right along a recently-built house.

(1) Turn left onto the yellow signposted path and cross a magnificent new pedestrian bridge. Thirty meters after the fork in the road, turn right onto Chemin de Lan Daou.

(2) At the end of the road, turn left into Rue de l'école, then right into Rue des Dunes. After 50 m, take Impasse Poul Gleisker.

(3) At the end of the Impasse, fork left into Rue du Launay: this is the old village lane of Port Blanc, where you'll find old houses and very old stonework. Continue as far as Traou Marquer.

(4) Shortly afterwards, take the path opposite (west), which is sometimes damp.
Before arriving at Quatre Vents, on the left of the path, there is an old watering place which used to be a wash-house.
At the end of the narrow road, turn right onto the Dolozic path.

(5) At a fork in the road, go down the small track on the left. At the end of the road, turn left and then right again, down to the Plage du Royo.

Turn right along the beach and admire the little harbour. Then head east along the coastal path (GR®34), which takes you through pebbles and sea cabbages (protected plants) to the dune beach. Continue along the coast on the customs path (GR®34), past a campsite and onto the coastal road opposite Ile aux Femmes.

(7) Take this road, still by the sea, back to Port Blanc.

(8) Opposite the grand hotel, you'll find the Sentinelle, an oratory on a rock.
As you go up towards the crossroads, you'll see the house of Anatole Le Braz, writer of Breton legends, on the right-hand side of the road. Turn left towards the harbour. At the end of a grassy area, climb up towards the rocks, and you'll discover a defensive wall, the Rocher du Voleur (Thief's Rock).

(9). Retrace your steps, continue left along the road and arrive at the harbour.

(10) At the end of the esplanade, the road rises again, past the annexes. Go to this large crossroads. Go straight ahead along the corniche road to Rue de la Chapelle, turn right then left and enter the enclosure of the Port Blanc chapel.

(11). All you have to do is climb down the weathered steps to the car park (S/E).

Notes

_ Start_: From the car park of Port Blanc chapel (harbor).

Worth a visit

A bit of history with the chapel of Port Blanc, which in the 14th century was a fortified guardhouse to watch over the roadstead, much sought-after by English privateers on their raids.

The Rocher du Voleur was a bastion armed with cannons; Vauban had the protective wall built, which is still visible today. The sentinel, as its name suggests, served as a shelter for a lookout man at the entrance to the harbor. At the foot of the rocks, you can still see the powder magazine with its stone roof.

A lovely walk, starting inland but with some beautiful sea views, and ending by the sea
Magnificent view
Be sure to wear good shoes, as there are a few rocky/pebble sections
We were the only ones there, which made for a very pleasant walk. The loop is about 15 km long

A pleasant, easy trail, but a few more details are needed.
However, not to be taken in wet weather, as we had to climb over a wall to continue our route as the path was impassable for several metres (mud at the ankles and puddles).

Hello,
We had a lovely walk on 12 May. Thank you for describing it. I've posted 2 new photos.
One comment:
Your image of the inside of the chapel is in portrait mode, and displayed in landscape mode. This means that it cannot be appreciated.
To display it in "portrait" mode, select the photo in Visorando and, in the top right-hand menu, click "Rotate" (once only).
Best regards.

The local council has put in place a diversion along part of the coastline because of the risk of rockfalls... it's a nice, quiet, well-marked walk!
