From the village of Lanmodez to the banks of the Trieux

de fr

A walk that begins with a stroll through the typical Trégor countryside, continuing for 40% of the route along the banks of the Trieux ria, before returning to the village of Lanmodez. Much of the walk follows grassy paths between fields and along the shore.

The path is poorly signposted, so don’t hesitate to use your GPS.

GR®34, marked in white and red

(4) Follow the tarmac road to the left for 500 m.

(7) Walk round the chapel, continue along the GR®34, which veers left at the end of a field, and start climbing up the tarmac road.

(8) Turn right, walking round the restored Ker Annio mill.

End of the GR®34

At the end of the path, turn left onto the tarmac road and you’ll come out onto the Route de Bonne Nouvelle.

(9) Follow this road to the right, ignoring the turn-offs to the left and right, and head towards the village of Lanmodez.

Hello.
Before Traou Brestan. At the fork in the road, take the small path on the right, pass Traou Stang and you’ll rejoin the road.

Hello, and thank you for your feedback.
I’m happy to adjust the route, but could you tell me exactly where the route needs changing?
- Is it at point 2?
- At the hamlet of Traou Bestan?
