Description of the walk

(S/E) Port car park (bar car park)
Partially marked in yellow andGR®34(white and red)

(1) From the car park, go up the road on the left towards the statue of the Bigoudène woman overlooking the port. Pass a wash house on your left and, in the bend, take the first path on the left that goes uphill (view of the small port of Porz-Poulhan). Continue along this yellow-marked path which descends into a wooded area and then climbs up to the right.

(2) Turn left, leaving the small road to Lestréouzien on your right. Continue to a fork (2 signs) and turn left, following the wide path. Continue along the small road, passing the Moulin de Kersandy.

(3) At the next road (Tréouzien), turn left and follow the path that leads to a small pond and the mill, which has been renovated (open to visitors). Continue along this path, which runs alongside a wetland and leads back to the car park where you started. Go around the port on the right, then take a path on the left.

(4) It turns right to climb up to the covered alley.

(5) Continue to a small road (Rue de la Corniche). Turn left, then right at the next crossroads. Head towards the village of Drégan, cross it and continue along the path that descends to the left to Guendrez beach.

(6) Go around the large house and take a path on the right through the dunes, which climbs steadily. It follows a stream, passes near a beautiful pond lined with irises and ends at a wash house, which you go around on the left.

(7) You will reach Saint They Chapel: a green spot that is ideal for a break. Continue along the path that climbs to the left and join a carriage road.

(8) Turn left and follow this path downhill (view of the sea). When you reach a small road climbing up to the right, continue and, at the road marked "sens interdit" (no entry), turn left along a house.

(9) Go down the steep little path and then, at a crossroads, turn right and then left at the fork to go down to theGR®34coastal path.

(10) Turn left and follow this path to Guendrez beach. Continue along the coastal path which climbs above the beach and continue to the Menez Dregan excavation site (closed to the public)

(11) Turn left to climb up to the archaeological site of Pointe du Souc'h and its interpretation centre. Follow the path through the dunes that descends to the coastal path and continue towards the small port to finish your walk (S/E).

For this walk, the app was very useful. Towards stage 1, a path in a wooded area had ferns taller than us and without the app we would have thought we'd made a mistake.
Nevertheless, it's a very nice walk, with part countryside and part coastal path. We particularly enjoyed the visit to the mill and the explanations we were given, but the mill is no longer in operation.

Very easy walk in the countryside with few people but some of the information was not very accurate and we had to turn back twice, fortunately quite quickly. A plus was the crêpes and galettes truck at the finish.

A weekday walk with my dog, starting from the little port of Pors Poulan. Very few people encountered....
Really magnificent and varied..... Trails through woods and fields, then views of the sea and down to the beach..... Absolutely top notch.....

A lovely walk with a wide variety of sites: sunken path, fountain and wash-house, mill, archaeological sites...
My curiosity as a walker is more than satisfied...
Thank you for this itinerary, to be recommended.

Before point 2 we hesitated. From the start, the path climbs as indicated and then descends to the Tréouzien mill. The map and the IGN trail suggest that the path goes up to the mill. In fact, you need to follow the path that follows the stream for 200 m before going back up. Apart from that, there's no problem with the route.

What makes this route so interesting is the variety of landscapes encountered: beautiful paths through undergrowth, along streams, and a truly superb finish by the sea. The little port of Pors Poulhan, its car park and terrace café were very busy yesterday, as was the final stretch by the sea. The renovated mill welcomed visitors. The route, which takes you back to the starting point after 3km to discover the mill and then the covered walkway, is rather confusing. It's a lovely walk that can end with a drink on the terrace, perhaps accompanied by a crêpe.

A truly magical place! It wasn't always easy to follow the route, but it's almost impossible to get lost here.
The views are magnificent, both on the coast and near the mill, further inland.
A hike I absolutely recommend!
Thank you

Shame the mill was still closed
A short detour to the Maison de l'Archéologie is very interesting, with a very friendly welcome.
thank you

I have to admit that I used the GPS application a lot... I'm not used to maps!
It's a really lovely walk, with lots of surprises - horses, horse-drawn carriages and magnificent scenery!
A great discovery!
