Departure from Pont des Olivets (D531), after the hamlet of Les Jarrands coming from Villard-de-Lans. Parking at the side of the road.
(S/E) Take the small road going uphill opposite the bridge. At the next fork, continue straight ahead, passing a hairpin bend
(1) Ignore the path that branches off to the left and head towards the hamlet of Méaudret, passing under a power line.
(2) At the three-way junction in the hamlet, turn right onto the wide track towards GAEC de l'Écureuil ( PR® de Pays signposting, yellow-green, which is fading).
(3) Return to the road. Follow it to the left, heading north, continue along the road and pass the hamlet of La Martinière. The road turns into a forest track. At the edge of the woods, turn left and you will reach a three-way junction. Continue left until you reach a junction of four tracks.
(4) Take the one on your left heading west (not marked, yellow-green cross). Follow the track for about 200 metres of elevation gain, following the summit section before it disappears when it reaches a wide perpendicular forest track.
(5) Continue off-trail, heading due west towards the ridge that can be seen in the distance.
(6) You will then rejoin the GR® de Pays (yellow-red) trail, which takes you left along the ridge to Gros Martel. The summit is marked by a cross and signs for hikers. Continue along the trail.
(7) Leave the ridge a little further on and descend into the forest, veering to the right. The first few metres are steep and often slippery.
(8) Cross the forest track and follow the GR® de Pays markings. A few hundred metres later, the path turns left and reaches the bottom of the valley. Continue along the forest path at the bottom of the valley until you reach a large Y-junction with signs for hikers.
(9) Turn right and follow this new track, keeping an eye on the paths on the left.
(10) Just before a hairpin bend at the edge of the forest, turn left onto the path marked with blue dots. Continue through the forest until you reach the Balcons de la Bourne.
The trail then winds "naturally" along the cliff overlooking the Gorges de la Bourne. When the gorges curve to the left, leave the edge of the gorges and continue north (blue markings). Join a forest track and follow it to the road to the hamlet of Méaudret:
(1) Turn right and follow the route in the opposite direction to the Pont des Olivets (S/E).
