Park in the car park at the Chapelle Saint-Jean.
(S/E) Take the small road on the left which leads down towards the Frinaudour bridge. As you approach the Frinaudour bridge, follow the yellow markings on the right. Walk along the top of the railway line for 100m, then turn right uphill. The path continues along a road.
(1) Then take the path on the left (yellow markings). At the next junction, continue to the left. Follow the Trieux stream above, ignoring the paths branching off to the right. You will come to a road which you follow to the left, passing in front of Coat Ermit and walking alongside the railway line for about fifty metres.
(2) Turn left to cross the railway line, then left again just on the other side. Shortly afterwards, you’ll enjoy a view of the Château de la Roche Jagu. At the junction, you can head down to the riverbank. Then walk back up for about 50 metres and turn left to return to the railway line and cross it.
(2) Continue straight ahead, then at the next junction, turn left onto the path overlooking the Trieux.
After 1 km, at a junction, turn left to cross a stream.
(3) Immediately turn left to go through a tunnel under the railway line. Continue straight ahead, then follow this path as it turns right to run alongside the estuary to the Maison de l’Estuaire (Manoir de Traou-Nez).
(4) Continue straight on to go under the bridge and take the forest road. At the second bend, turn left towards Lancerf (yellow markings). Walk along the heights of the Trieux. Further on, you’ll come to a junction with a wide path.
(5) Follow the path to the left, keeping to the yellow markings, and rejoin the road. Turn left to reach a T-junction.
(6) Ignore the road on the right leading to the chapel; continue straight on down to the railway line, then cross the level crossing.
(7) Continue along the path on the right which runs alongside the estuary to reach Traou Du.
(8) Go under the bridge, then cut across the road and head up, south-southeast. Ignore a path on the left to reach the hamlet of Kericun.
(9) Turn left, then right after the bend, and head uphill through the woods, keeping straight on.
(10) At the junction, turn right to reach Ty Caër. Walk past this house, which is beautifully decorated with flowers, and head down into the valley (yellow markings).
(11) At the junction, continue straight ahead to cross the stream, then head back up to a junction at the end of a small road.
(12) Leave the yellow markings and turn left onto the wide path (partly tarmac) for 200m. At the first junction, turn right (ignoring a path on the left which goes downhill and is blocked by a chain). Follow this path (often muddy and rutted) to the junction with a road.
(13) Take the path opposite for 200m, then veer left and follow the narrow path (somewhat obstructed by branches and holly) which follows a boundary line. After about 400m you come out onto a wide path. Take this on your right and join the road (elevation 79).
(14) Cross the road and take the path opposite (often with deep puddles). Continue, ignoring two paths branching off to the right.
(15) Return to the forest track and the yellow markings, then turn left. After 500m, at the junction, leave the yellow markings again and continue straight ahead.
(16) Join the road and turn left to reach the hamlet of Toul Lan. Take the second small road on the right that goes downhill to reach the Saint-Jean Chapel and the car park (S/E).
