Description of the walk

(S/E) From the Ducs car park, head east towards the climbing site.

(1) When you reach the climbing site, cross the small ford of the Combe d'Oyans stream and continue north-northeast. Keep going in this direction.

(2) About 1.7 km from the start, turn right at a right angle onto the narrower path heading northeast (on the IGN map, this path is only marked halfway).

(3) Join the trail coming from Beauregard-Baret at the Saint-Isérat signpost and turn right (south-east) towards the Col de Sonnaize.

(4) At the Col de Sonnaize, continue in the same direction until you reach the Pas du Loup.

(5) Be careful at the crossroads. Turn left (east) towards Montagne des Ussets, then Col de Tournier.

(6) At the pass, follow the road on the left towards Source de Font Pourcel until you reach a crossroads about 350 metres further on.

(7) Turn right, then after 170m, continue in the same direction on a slightly narrower path which then joins the wide track that descends towards Les Pignes. Follow this track, continuing straight ahead.

(8) Go through the fence, turn left and head south towards Verdu.

(9) Follow the path on the right that passes under the seven poplar trees to Saint-Genis.

(10) Take the road on the right, then turn left and continue for about 3 km until you reach a gate on the right.

(11) Go through the gate and follow the path downhill to the car park (S/E).

Beautiful hike, beautiful views, well-marked route. The foothills of the Vercors are superb. Return by road necessary to pass between the cliffs.

Pleasant hike. You can avoid returning along the same route by taking a detour, but this makes the walk longer!

A hot day, perfect for a hike with plenty of shade. Simple and well-marked route. Beautiful views of the Roman valley and the Vercors cliffs. Perfect.

A very beautiful route, well sheltered in hot weather, with lovely views of this valley. It's a shame, however, that there are 3 km of tarmac at the end, which spoils the overall impression

Parish specific to Brittany hike, but unfortunately after point 7, there is a lack of signposting. Some additional markers would be welcome.

A pleasant, easy hike. We added the climb to the orientation table at the ruins of Rochefort Castle (on the left just before the gate at the end of the hike), which adds about 1.5 km, but the view is worth the detour.

My IGN map (2016 edition) did not show the same trail information as the description, and seems more accurate. So, from 1 to 3, we couldn't find the information provided. However, it was no problem to get to the Col de Sonnaize and the Pas du Loup. There, we missed the junction with trail 5, which doesn't seem very natural (trail marked with a cross), and joined trail 6 via the main trail (marked in purple on the map). The main problem arose between points 7 and 8, where the suggested trail is blocked, marked as private and prohibited. We therefore had to take the trail marked Saint-Genis, which leads back down into the valley at the foot of the opposite slope.
We rejoined the circuit at the hamlet of Les Combes. The end of the loop was straightforward.
A beautiful hike with some stunning views, but it's best not to be too bothered by the discrepancies between the information in the description and what you find on the ground.

Great hike, we followed the GPS route with no problems. It's mainly in the woods, which is nice for summer when it's hot.

Hike through boxwood and deciduous trees with sweeping views of the valley, Rochefort Castle and the plain. Many possible variations: visit the gorges, return via Grimaud if you want to avoid the road (which is quiet and offers beautiful views), orientation map of the castle... The GPS track is very useful, thanks to the author

A lovely family walk.
Beautiful scenery, clear weather, birds, a few flowers, not too many people, but more than I had imagined (the car park was full on Monday!). It must get busy on weekends when the weather is good.
The initial climb isn't steep; once you reach the flat section below La Condamine, be careful not to miss the small path that branches off to the right (the GPS track shows a "path" that starts a little further on, which seems less good than the path we took, judging by what I saw when it joined ours).
The viewpoint near the Pas du Loup is not very suitable for a snack break and is quite small, so it is better to opt for the large lawn at the Col des Tourniers.
One thing missing: the secluded shelter at the Col des Tourniers is not signposted. Although quite small, it could be useful in case of a storm.
Be careful: at waypoint 8 (fence), do not go down the road that leads to Les Pignes (it is a few metres below and tends to attract your attention, but there is a long way to go further down).
Gate:
indicate in the description that it is located after the climb to the Col de St Genis (it can be seen on the map but...).

We did this hike in strong southerly winds, but we were often sheltered and were able to enjoy the beautiful views. I followed the route on my phone app, which was very helpful, as it seems that the planned route included some off-trail sections (it wasn't very clear under the poplar trees). Like others, I was a little disappointed by the end on the tarmac, but the surroundings remained very pleasant. I'm very happy with my day. Thank you to the author.
