At La Roche, after Saint-Marcellin-en-Forez, turn left towards Périgneux. Park your car at a place called La Gare, on the right as you come from Saint-Marcellin; there are plenty of parking spaces available, right by the old station.
(S/E) Follow the old railway line towards Luriecq.
(1) Note the return path on your left and continue straight on to Nus station, following the D498 for the final 150 metres.
(2) Shortly after the station, head left towards the hamlet of Sommériecq. Pass through it, then turn left, heading down towards the Bonsonnet and cross the stream.
(3) Keep to the right at the bend to head back up towards Les Barraques. Cut across a side path and carry on until you reach the very first houses in the hamlet.
(4) Take the Route de Périgneux (D32) on the far left towards La Tuilière.
(5) At the fork in the road, take the left-hand road, pass through La Tuilière and arrive at Fressonnet.
(6) In front of an imposing farmhouse, turn left and continue through the hamlet. Then leave the tarmac road and head back down towards the Bonsonnet, which you cross again via a footbridge. You’ll reach a crossroads.
(7) Take the path on the right and then immediately turn left at the three-way junction. Stay on this path below the hamlet of La Mûre until you reach the old railway line.
(1) Turn right and head straight back to the car park (S/E).
