Coming from Tournon on the D86 towards Cornas, pass the hamlet of La Vinsonne. As you leave the hamlet, park just after the bridge on the right at the clearing (cherry orchard).
(S/E) Take the track along the river.
After the orchards, turn left onto the path. This splits into two.
(1): Leave the path that goes straight ahead and take the path on the right. This path winds steadily with the river below on the right. Pass a large rock where you can begin to see the Rhône.
Then cut across the terraces of an old chestnut grove. Continue climbing the winding path up the hill until you come out onto a meadow. After a few dozen metres, you will reach the ruins of Pommery.
(2) Go past the ruins and take a short detour to the left for about a hundred metres to discover the superb view of the Drôme and Isère plains and the Vercors. Retrace your steps.
Turn left behind the ruins and exit the park.
(3) Take the carriageway immediately on the left heading south (ignore the other path to the south-west). You will come to a tarmac road. Turn left and pass behind the large farmhouse at Serpianne. Continue along the road until you reach the hamlet of Les Clots.
(4) In the very tight double bend, take the wide path that passes through the orchards. Be careful, the signpost is marked on the road but is difficult to see. This path winds through the undergrowth. At the fork, the path descends steadily in hairpin bends. You can continue straight ahead to admire another beautiful view.
(5) Retrace your steps to begin the descent through the forest until you reach the fork in the path you took on the way there.
(1) Continue straight ahead and return to the starting point (S/E).
