Description of the walk

Access: Take the road opposite the Rochefort-Samson town hall and head for the Parking Escalade car park (that's its name), at the junction of Chemin des Ducs and Route de la Montagne in the hamlet of Les Ducs.

Yellow signposting
(S/E) With your back to the signpost, turn left onto Chemin de Saint-Genis (tarmac). At the first bend, leave the road and continue straight ahead on the small path. 30 metres further on, go through a gate and follow the path under the trees.

Turn right and go through a gate that leads to the paved road at the Château d'Eau signpost. Follow this road uphill to the left towards Pas du Loup. After the right-hand bend, you will arrive at the Col de Saint-Genis signpost.

Red-yellow signposting
(1) Leave the road and turn right onto the path towards Coquat. The path climbs gently for about 400m and joins an esplanade at the Coquat Nord signpost (you can make a return trip to the right to the ruins of the Château de Rochefort).

Continue straight ahead on the main trail, ignoring a faint path on the right shortly afterwards, to arrive at the Coquat Sud signpost 80m further on.

Yellow signpost
(2) Turn left towards Grimeaud and immediately after, ignore the path that branches off to the left. The trail continues through the boxwood (or what remains of it!) and reaches a gate 300m further on.

N.B. At this point, a prefectural decree informs you that dogs must be kept on a leash and that you are entering a private area, but that crossing rural path no. 17 is permitted. Please follow the instructions and close the gates behind you.

Climb over the gate (this requires climbing three steps) and continue along the path. A little further on, there is a shelter (for hunters or shepherds?) in the middle of the path, which you must cross to continue on your way. You will arrive at a flat area with a view of the Montagne du Mussan.

Continue along the path and shortly afterwards, a trail parallel to the path allows you to bypass a spring that flows (depending on the season) in place of the path. The trail rejoins the path about 300m higher up, just before an esplanade with two hunting posts.

(3) Continue along a relatively flat section. N.B. All the paths on the right, visible on the map, are not accessible as they are blocked by a fence. Join a wider path which narrows further on, then go through the exit gate (3 steps). Join the Grimeaud signpost.

(4) Follow the path downhill to the right, leaving the path on the left that leads to Les Combes. Walk along the fence, pick up a path coming from the left and reach a house. Continue along the path, turn left and look for a trail on the right a few metres after the turn.

(5) Leave the path and turn right onto the trail (Bouvaret sign). Go through a fence and follow the trail uphill until you reach a path. Turn left onto this path until the next crossroads. Take the right-hand track and begin a gradual climb. A little further on, a logging track coming from the left crosses the path for a short distance (not visible on the map) then moves away, ignore it. Continue climbing, cross a fence and you will reach the Courbière signpost.

(6) Take the path on the right towards Pas de Bouvaret. The slope becomes steeper and, after a few hairpin bends, arrives at Pas de Bouvaret. A return trip along the small path on the left leads to a rocky outcrop with a view of the valley.

(7) Back at Pas de Bouvaret, continue straight ahead on the path that descends, turns left and joins the Bouvaret signpost.

Red and white signposting
(8) Continue straight ahead towards Sous le Pas de la Pierre, through an area of meadows and beech groves. Go through a wooden gate and continue downhill to the signpost.

Red-yellow signpost
(9) Turn left towards Pas de la Pierre, staying on the main path. At the next fork, the path turns sharply left and begins a steep climb to Pas de la Pierre. Make a round trip to a viewpoint by taking the path on the right.

Yellow markings
(10) From Pas de la Pierre, begin the descent by continuing straight ahead. The start of the descent is very steep, so take care, but the slope gradually levels out to reach a flat area (hunting lodge). 100m further down, you will come to a path. Follow it to the right until you reach the Pourcel signpost.

(11) Leave the path that branches off to the left and the trails that branch off to the right of the signpost (not very visible). Turn left at this signpost to find a small trail that descends just after it on the right (yellow cross, but you will find the yellow markings further on!). The path is slightly steep at first but becomes steeper when it reaches the boxwood trees. Continue to a crossroads, ignore the paths on the right and left and continue straight ahead across a meadow. You will arrive at an esplanade with the Col des Tourniers signpost.

(12) Leave the path opposite towards Pas du Loup and turn left at an acute angle onto a path towards Éperon des Ussets. A few metres further on, leave the path that continues into private property and turn right to descend onto a path that runs along the hillside. At a crossroads, continue to the right on more or less flat ground, ignoring the tracks that climb steeply to the right. Continue the gentle descent to the Éperon des Ussets junction.

Red-yellow markings
(13) Leave theGRP® on your right and continue straight ahead towards Les Combes. Go through a fence and continue downhill. The trail widens and further down you have to cross another enclosure. The descent ends as you approach the hamlet. Leave the access to the climbing site on your right and continue straight ahead until you reach the asphalt road at the Les Combes signpost.

(14) Turn right onto the road that climbs back up to the Col de Saint-Genis (beautiful view on the right of the Montagne de Morettet climbing site).

(1) When you reach the Col de Saint-Genis, turn right onto the road to follow the same route as on the way there and return to the car park (S/E).

Notes

Crossing the two "steps" is quite physically demanding, both on the way up and on the way down, so walking poles are strongly recommended.

Twice, you have to climb three rungs to get over a fence (there is no other way).

A very pleasant hike. I did it in the middle of summer and the coolness of the Vercors forests during this period is very pleasant. To really enjoy the view of the Drôme, you need to climb up onto the rocky outcrops when you reach the "Pas de Bouvaret" and the "Pas de la Pierre".
The difficulty of the hike seems to me to come from the descent from the "pas de la Pierre", which is very steep. Using your hands is not an option and I think it is essential to have good grip shoes.
I only gave 4 stars for the description, which I think is very well done in a very complicated context. There are many paths and trails, and the markings are really unclear (in this regard, it's a shame that the markings only appear at junctions, and even then only sometimes. When there is a long stretch between two forks, there are no intermediate markings to reassure you). The 4 stars are because I got lost. Nothing serious, but I didn't end up where I was supposed to be. I got lost somewhere in the middle of point 11. Perhaps I didn't pay enough attention to "continue straight ahead into a field", and instead of returning to the car park, I headed towards "Beauregard". I was picked up by two charming female hitchhikers, so I'm not going to complain.
Enjoy your walk, everyone.

We did this hike in glorious sunshine, above the valley mist.
Overall, it is a physically demanding hike, but the scenery makes it well worth the effort. The descent to Pas de la Pierre is a little difficult and slippery due to the carpet of leaves.
We strongly recommend taking the last paths at the 2 Pas to enjoy the views and maybe stop for a snack. Be careful because it's narrow and the cliff is steep.

I have done this route several times, in both directions. The snack stop at either Bouvaret or La Pierre is worth the trip for the panoramic view. When it's really hot, you're almost always in the shade! In this direction, the descent from the Pas de la Pierre requires some caution!

A very beautiful hike in glorious sunshine, with magnificent 360° views
However, the descent was quite dangerous on the rocky path as there were still patches of snow!
But the scenery is truly breathtaking
Highly recommended

My suggested variations:
at point 2, return to the castle for the orientation table at 630m with a beautiful view of the Rhône valley and Ardèche.
at point 11, take a detour to the Font-Pourcel spring for a refreshing break, then rejoin the circuit via the path descending west-northwest.
at point 12, "Col des Tourniers", do not descend via the GRP but take the PR towards "Grotte des Ussets" (worth a visit) then rejoin the PR heading south, which joins the GRP.
Otherwise, in clear weather, the hike is simply magnificent.

Beautiful hike with some very pretty sections in the forest, but very slippery terrain at this time of year due to leaves and humidity

Very beautiful hike.
I would definitely do it in reverse, starting at the Pas de la Pierre.
Some sections are quite steep and should be avoided after heavy rain.
I only came across two people who were jogging.

A beautiful hike, despite the weather. We encountered rain and fog upon reaching the summit and were unable to view the landscape, which was unfortunate. The Passage du Pas de la Pierre was challenging due to humidity and slippery terrain.

Great hike, despite the clouds, humidity and fog: no view at the summit (but it felt like we were floating on a rock, so it was still an amazing experience!), and a tricky descent from the Pas de la Pierre with the humidity and an 8kg backpack (for training). But great training, haha! Thanks for the hike

A beautiful, well-marked hike, and we also had the route on our GPS.
There was only one difficulty at point 11 (Pourcel): the yellow markings indicate the Col des Tourniers via the "road" that leads to the source of Pourcel. At the source, turn right onto a small path marked in yellow, which eventually rejoins the GPS track further on. We couldn't find the path at marker 11, a trail blocked by barbed wire if you followed the GPS track...
No technical difficulties but a tricky section when descending from the Pas de la Pierre for 200 m.

Great walk... the interest lies in the approach and the view of the two sisters... then the descent with a view of the plain of Valencia.
BE CAREFUL... the climb (between 9.5 and 10) to the Pas de la Pierre is dangerous in wet weather... the ground is very slippery. The descent from the Pas de la Pierre is in the first 200 metres and should be taken with caution... (from 10 to 10.25)

At point 5, the path to the Pas de Bouvaret is not marked... (no signposts or paint...) just be careful... don't go down the road that descends to the left... but take the small path slightly to the right, before the field.
