In Tréguier, from the central square of Martray, after passing under the arches of the town hall, go down Boulevard Anatole le Braz. Before the Black Bridge, spanning the Guindy, turn left to enter the Parking des Poètes car park.
(S/E) Leave the car park heading south-west (with your back to the bridge). Pass under the pier and admire the natural spring on your left. Continue along the path that runs alongside the Guindy.
(1) Cross the Saint-François footbridge and continue on the left. Continue straight ahead along Rue des Mimosas and continue on the left along Rue du Vieux Couvent, then Rue Saint-François as it continues. As it climbs, it makes a sharp right turn.
(2) Before the viaduct, take the path on the left. It descends to join the Guindy. Continue along the path alongside the river until you reach the first houses. Cross the road and continue opposite.
(3) Before a house, take the path on the right that climbs northwards. When you reach the road, turn left and after 100 metres, take the path on the right. At the crossroads, turn left; very quickly, the road becomes a path.
(4) Continue along this path, turning left. At the end, cross the road and continue straight ahead to reach the departmental road (D127). Take it on the right.
(5) After the drinking water plant on your right, turn left and then right onto the first path. At the farm building, leave the path by turning right. Cross the D70 and continue straight ahead, slightly to the left. Continue along this road, cross Kélou Mad and you will reach the Chapelle de Bonne Nouvelle.
(6) Leave the chapel on your left, then continue right on the road. Cross the road and continue straight ahead. At the fork, turn right, then at the end of the road, turn left. After 100 metres, you will reach a crossroads.
(7) Take the wide path on the right.
Note: The presence of this wide, sandy path with a uniform surface is explained by the fact that it is the route of an old railway line that ran from Perros-Guirec to Paimpol via Tréguier until the 1950s.
Follow this track, continuing straight ahead. Before crossing the D70, note the old Plouguiel railway station on your left. At the next crossroads, continue straight ahead. From here, the track becomes wilder and narrower. When you reach the Kerdéozer viaduct, a large sign indicates that it is prohibited to cross. Take the steps on the left and turn right at the bottom. You will come to an intersection that you passed on the way there.
(2) Follow the same route as on the way there. Go straight down and keep to the right-hand side of the road. In Rue des Mimosas, don't forget to take the path on the right.
(1) Cross the Passerelle Saint-François again and pass under the pier, then turn right then left to follow the wall on your left. You will reach the Parking des Poètes (S/E).
