The Corniche de l'Armorique starting from Plestin-les-Grèves

Setting off from Plestin-les-Grèves, you very quickly catch sight of Grève Saint-Michel, where, at low tide, the English Channel recedes into the horizon, creating a vast expanse for all kinds of wind sports: sand yachting, windsurfing, kite flying, etc...
Then, following theGR®34, you walk along the Corniche de l’Armorique, discovering Lannion Bay and the mouth of the Douron. Opposite lies Locquirec and Finistère.
History is also present in the form of the Gallo-Roman thermal baths.

Description of the walk

Car park at the boules court, Rue de Lestrezec, near the stadium.

(S/E) Leave the car park by turning left onto Rue de Lestrezec.
At the crossroads, turn right onto Rue de Guergay. Cross one street and continue to the end of the road, then turn left onto Guergay Bras.
Cross straight across Avenue des Frères Le Gall (D786) and continue along Rue de Traon an Dour.
At a place called Traou Dour, in a right-hand bend, take the second path on the left. This path becomes a track.

(1) At the second junction, turn right and join Rue de Trévoz. At the end of the street, turn right and then left 125 metres further on.

(2) Take the path on the left. You will join theGR®34, marked in red and white. Continue left along the coastal path (GR®34) to Pointe de l’Armorique. The path becomes a road and reaches a crossroads.

(3) TheGR® continues straight ahead, but a sign indicates that it becomes impassable at high tide. We therefore recommend taking the alternative route by turning left. Turn into Rue de Porz Mellec and take the first left. Cross the junction by continuing straight ahead, then turn right into Rue de Milin Avel.
At the end of the street, continue straight on along the path. At the junction, turn right and continue straight on to rejoin a tarmac road.
Turn left, then take the first right and continue straight ahead. Cross the D42 to rejoin the standardGR®34.

(4) Join theGR® on the left. Continue along the coastal path.

(5) Take the path on the left and continue straight ahead along it through a pine forest.

(6) On the left are the ruins of the Gallo-Roman baths at Hogolo.
Continue straight on along the path. At the end of it, head towards the chapel.

(7) On the left: the Sainte-Barbe Chapel (see photo, reference below). Follow the path, keeping the chapel on your left, and continue straight ahead.

(8) When you reach the road (D42), turn right, then 40 metres further on, turn left past a detached house. Continue straight on past the Keramanant residence. Cross Rue du Vieux Moulin and turn onto a path slightly to the right.

(9) Take the path on the left and follow it to the Route de Peulven. Then turn left and then right onto the A-road.

(10) Cross the D786 and turn left onto Rue de Kerglas. At the end of the street, first turn left then right onto Rue Saint Roch. At the crossroads by the water tower, turn left to return to the car park where you started (S/E).

A beautiful walk around the headland, with fantastic views over Locquirec and St Michel en Greve. There are also the ruins of a Roman bathhouse? Fantastic. It’s best to follow the GR34 round the headland and then head back from the chapel at St Efflam to the Chapel of St Barbe.

It’s quite a long walk; without the app, it’s impossible to do this hike. There are no street signs or place-name signs, and despite the route description being very detailed, it’s quite difficult to find your way around – a stark contrast to the actual terrain.
