(S/E) From the carpool car park, follow the D57 towards Plogastel-Saint-Germain for about 100 metres. At a beautiful beech tree, cross the road carefully and take the small road on the right until you reach the last house.
(1) Turn left behind this house and follow a path that winds through a wooded area. The numerous marker posts make it easy to find your way. The path leads to a footbridge over a stream.

(3) Cross this small road and continue straight ahead, passing in front of an old farmhouse in Saint-Avé Huella (under restoration in 2025). Cross another small road and descend straight ahead via the access road to a pumping station. Go around this enclosure, continue along the path overlooking a stream hidden by vegetation and arrive at a small road.
(4) Turn right, then left, cross this small road, take the path behind a house and continue straight ahead until you reach the D57, a major road leading to Plogastel-Saint-Germain. Cross it carefully and continue along the path that joins a small road.

(8) Take this path and cross the Pont-l'Abbé river. Ignore the first path on the right and take the next one, which goes uphill. At the various junctions, ignore the paths branching off to the sides and continue to the edge of the woods, bordering a meadow.
(9) Turn left and continue straight ahead on a steady climb, ignoring the side paths, until you reach a crossroads.
(10) Continue straight ahead along the path, which is circular and heads north. Turn right, walking alongside the fields on your right, and continue towards the Quilliou farm.

Opposite, take Rue de la Fontaine (beautiful sundial) and follow the path as it continues, turning right.

Ignore the paths that descend into this valley and arrive at a small wooden bridge to cross a stream.
(15) Turn right and continue towards the hamlet of Kervil. Go around it on the left and you will come out on the D140, where you leave the mountain bike trail.
