Park in the Maison de Pays car park.
(S/E) Walk along the Albarine river towards the town centre until you reach the church. Immediately after the church, turn left onto Rue du Cuchon, which climbs and then gives way to a path that runs along the bank of the Ruisseau de Brévon.
(1) At the junction with a tarmac road, near the Chapelle Saint-Domitien chapel, turn right and continue uphill to the hamlet of Buges. At the Buges sign, turn left and walk up through the village to an old drinking trough filled with flowers and marked with a yellow sign.
Turn 90° to the left and climb a stony path for about a hundred metres until you reach a fork.
(2) Take the path that climbs to the right along the slope of Mont Jud and follow it to the hamlet of Morgelas.
(3) At the entrance to the hamlet, take the street on the left, climb for about 100 metres, then turn left onto a wide path that climbs above the houses. Follow it to a hairpin bend over a small stream.
(4) About 50 m after the stream, take a narrow path on the right, perpendicular to the road, which climbs straight up the slope for 50 m, then follow a gentler path on the right that climbs up the bottom of a valley through the forest. Follow this path for about 600 to 700 m.
Almost at the top, when it becomes narrower, follow a dirt path on the left that climbs straight up the hillside. Pass the ridge, leaving a perpendicular path on your left.
(5) Descend opposite, on the other slope, via a well-established path. Pass two paths on the left and arrive at a tarmac road.
(6) Cross it and enter the woods for about 20 metres, turn 90° to the right and walk through the woods, heading north, for about 50 metres. You will come to a wide forest track, which you take to the left, going uphill. Cross a fir forest.
At the end of the track, you will come to a crossroads with several paths and trails.
(7) Take the path furthest to the left, marked in yellow, with a coniferous forest on the left and deciduous bushes on the right.
Continue south, passing several paths on your right.
(8) Pass under the power line. You will then enjoy a beautiful view of La Dombe.
(9) At the bottom of the descent, continue along the path, turning left twice.
(10) After crossing an area of meadows bordered by hedges, turn left (blue markings) and join the Angrière road.
(11) At the crossroads, take this road on the right for 500 metres.
(12) Turn left onto a path. The blue markings on the post indicate a change of direction. When the path meets the road, go slightly up to the right, then turn left onto a path that passes in front of a house, right next to the façade. Go down to a meadow where a blue marking on a tree trunk indicates to turn left. Descend the path to Pont Rion, where you will join the D73.
(13) Cross the crossroads and the road bridge and go up the road.
(14) Turn left to cross the village of Serrières. Take the highest street closest to the hillside and continue straight ahead.
Cross the hamlet of Grange Neuve and join the railway line.
(15). Go under it, turn right and go up to a metal footbridge. All that remains is to cross it to reach the starting point (S/E).
