(S/E) You can start from the cemetery in Poleymieux, where there is easy parking. Continue along the road in the opposite direction to the village. A sign will show you the drystone shelters you will encounter along this path.
(1) Leave the path and head up to the left. After the short climb, turn left. The path passes between vineyards and drystone shelters, which have been well restored and feature clear explanatory signs on both sides. After about 500 metres, you will come to a road. Cross it and take the path opposite, which climbs for about 50 metres. At the end, follow the road on the right, which will take you to the Risler Tower.
(2) Below the Tour Rister, there is a small square with an iron cross and information panels describing the Mont d'Or geological trail. Take the path on the left of the panels. At the crossroads, take the road on the right (Chemin du Pavillon). Continue straight ahead on this road, which climbs gently through the woods to a place called Le Pavillon. At this building, on the left, a narrower path climbs through the box trees. At the first intersection, turn left, following the markers for the geological trail. The path quickly leads to the small road that serves the highly sensitive communications facilities of Air Base 942. Continue along this road.
(3) At the bend, take the path that descends opposite, into the forest (marked with geological trail markers). The path descends through the woods. In wet weather, it can be very slippery. Ignore the path that branches off to the right into the large meadow.
(4) Take the path on the right, which is steep and potentially slippery. The path becomes more even and pleasant. After about 500 metres, ignore the first path that descends to the left.
A path branches off to the left, downhill, along a small wet ravine: take it and follow it.
Be careful at the intersection, after 100m, take the path that branches off to the right, across the stream, and not the one that goes straight down. You will pass some impressive drystone shelters in ruins. The path winds through the forest along old walls, then runs alongside a long clearing.
(5) At the intersection, take the path that descends to the left. Ignore the path that descends to the left about 300m further on.
(6) Take the path that branches off to the right at a wooden post. The path descends through the woods and can be slippery in wet weather. Ignore the marked path that descends steeply to your left and instead take the one that climbs to your right. It will lead you to a crossroads after a clearing. Turn right. The path leads you to a concrete road.
(7) Turn right and follow the concrete road that climbs towards the forest. There is a beautiful view of the Saône valley at the bend at elevation 409. At the edge of the forest, you will pass an old wash house. Ignore the road that branches off to your right.
(8) Take the road that branches off to the left at the pass. You will soon arrive at the old Poleymieux mill and the picnic area. Continue straight ahead on the gravel road, ignoring the path that branches off to the right.
(9) About 200 metres further on, a narrow, steep path descends to the right. Take it. Through the woods, it leads you to a vineyard and then plunges down to the right, very steep and potentially slippery. Shortly after a beautiful golden stone quarry, you will arrive at a carriageway.
(10) Turn right and continue straight ahead on this path, which will take you back to your starting point (S/E).
