Departure from Place de la Halle in Pont-en-Royans.
(S/E) From the square, walk a few metres to the right and turn left onto Rue du Temple. Climb up a marked path through the narrow streets of Vieux Bourg. When you reach Chemin du Bourg, follow it to the left, go through the medieval Sainte-Agnès gate, then turn right about 50 metres further on (sign and markings) onto the path that climbs up the mountainside.
(1) At the first intersection, turn right, going back and forth, heading south-east, on the path up to the viewpoint and the Trois Châteaux orientation table.
(2) Return to the previous intersection.
(1): On your return, turn right, heading north towards Col de Toutes Aures. Stay on this well-marked path and continue north. Further on, the path makes a 90° turn to the right. Continue south-east, ignoring the next fork (difference between thePR®® route on the IGN map and the change in the path on the ground). The path descends slightly, then after another 90° turn to the left, climbs northwards.
(3) At the three-way junction, follow the path on the left, climbing up to the Campeloup road. Follow it to the right and reach the Col de Toutes Aures.
(4) At the intersection at the pass, you will find yourself facing three roads. Follow the middle one, the D292, towards Les Champs, which continues straight ahead, despite the signpost.
(5) Walk past the Champs farm, leave the D292 and follow the small road on the left that climbs towards the Arnaux stopover lodge. Just before the lodge and before the hairpin bend, take the path on the left at the bottom of the car park, heading south-west. At a bend, the marked path turns right, heading north, and joins an intersection.
(6) Turn right heading north-east onto the Serre Cocu path, walk past a beautiful farm on your right, continue and reach the Rintanpan crossroads (mast). Then take the well-marked path on the left, which climbs to the top of Serre Cocu.
(8) Return to the previous intersection.
(6) Turn right, heading south-west, onto a path that continues for almost 2 km and crosses a track. Stay on this well-marked path, ignoring the various tracks that branch off. You will cross to the other side of the valley. Continue to the road and follow it to the right until you reach the Mûrier mast.
(8) Take the small path on the left, heading south, and join the road, turning 90° to the left. Follow this small road to the old Belière farm, where the road gives way to a well-marked path that descends to a stream, which you will cross by fording. Climb up opposite and continue to the hamlet of Courtevoux. Join and follow the Chemin du Réservoir, skirting the Paradis neighbourhood. Take the Chemin du Bourg.
(9) Reach the old village. From there, all paths lead back to Pont-en-Royans, allowing you to visit this old medieval village at your leisure (S/E).
