Park in the car park of the Bignan sports hall.
(S/E) After leaving the car park on the right, take the D150 towards Colpo (yellow markings on the electricity pole opposite the stop sign). Then immediately turn right onto Rue Anne de Bretagne towards the Kergoat garage, leave the garage on your right and continue straight ahead along the sunken lane to the hamlet of Treuliec.
(1) Leaving the sunken lane, take the D150 to the remarkable Treuliec calvary in the centre of the crossroads and climb towards La Motte - Le Cosquer. Turn right at the La Motte - Le Cosquer sign.
(2) When you reach the bottom of the hill, turn left onto the path, leaving the lake on your right. At the top of the steep slope, turn right onto the sunken lane behind the embankment (do not enter the field). Take the second sunken lane that climbs to the left. At the top, turn right and follow the fence. The path descends gently.
(3) Continue to a place called Kerdanet. The path turns left and runs alongside the tarmac road, joining it after a few metres. Continue to the end of this road.
(4) At the end of the road, turn right towards Roscornec. You will pass two wind turbines on your left. Continue straight ahead on the tarmac road, which becomes a dirt track and runs alongside a wood. At the end of the track, turn right into the woods and do not enter the meadow. Follow the yellow markings down the path through the woods. When you reach a road, take it on your left and turn right after about 30 metres. Descend towards the hamlet of Kerbasque.
(5) At the end of the tarmac road, turn left onto the path just in front of the entrance to the property, then left again after 40 m. Continue along this path, which becomes a tarmac road in the hamlet of Kohcastel (Cohcastel on the map) until you reach the crossroads.
(6) Turn right towards the Chapelle du Bezo chapel. Continue straight ahead. Take the path that climbs up to the left via a hairpin bend towards the Fontaine Sainte Nolwenn fountain (picnic table).
(7) Turn right onto the marked path that leads to a road. Turn left onto the sunken path. Continue following the yellow markings to the D150. Please note: as the path is close to the Poublay motocross track and mountain bike routes, you may encounter two-wheeled vehicles.
(8) Cross the D150 and continue through the village of Poublay. Turn left at the end of the village. Continue along this tarmac road, turn left towards Kergunu and pass a calvary on your left. Do not cross the private property (signs saying "no entry").
(9) Turn left onto the path at the gable wall of the Kergunu farm. The marked path will take you around the houses of Kerhuilin. Turn left onto the tarmac road, which becomes a path.
(10) Turn right onto the path and continue through the woods, following the yellow markings. At the edge of the woods, turn right onto the small meadow and take the path downhill.
(11) Turn left at the end of the meadow, then right onto the path that runs alongside the stream in the woods. At the edge of the woods, the path climbs diagonally across the fields. At the top, there is an unobstructed view of the church and village of Bignan.
(12) Cross the road and the hamlet of Guérignan. The year 1726 is engraved on the lintel of a door of a remarkable abandoned farmhouse. Turn left onto Rue Pierre Guillemot, then left again onto Rue Yves Le Thieis, which turns right towards the sports hall (S/E).
