To reach the starting point, leave the village of Roybon via the Monfalcon/Hauterives road (D20). Shortly after leaving the village, you will cross a bridge over the Galaure. Immediately turn right onto the small road leading to the cemetery. Park as soon as you can on the wide hard shoulder on the left (there is plenty of space).
(S/E) To start your walk, leave the cemetery path, take the abandoned slip road opposite and head off to the right (west). You will walk about 100m along the D20, so be careful as cars drive quite fast.
(1) Ignore the first road on the right (this will be your return route) and take the next one on the right.
(2) It climbs gently; this is the old tram line that linked Lyon to Saint-Marcelin. Follow it, with several bends to the right and left, until you reach the Chambarans military camp.
(3) You will then have completed just under half of the route. In front of the camp, note the monument erected in memory of the Chambarans resistance fighters. From your arrival point, turn right (east). Walk for about 1 km on a road that is fairly easy for cars to drive on but where traffic is rare. You will come out onto the D156, which you take to the right (south-east).
(4) Leave it after about 50 metres, turning left (north-east). At the end of the straight road, continue along the small road that veers to the right and leads you to the hamlet of Croix Frère Jacques.
(5) Then turn right (south-east) onto a gravel road. Continue for a while until you are back on tarmac and reach a T-junction.
(6) Turn left this time, then take the first right (Route du Vatilier). You will pass a few farms.
(7) Turn left onto the farm track (sign).
(8) Cross the D156 (be careful, this is in the middle of a bend and visibility is poor).
From the start, you have either climbed or walked on flat ground. In no time at all, you will be back down again! You will return to the D20.
(1) Turn left and you will see your vehicle, which you will return to (S/E).
