The Rock of Séguret

A beautiful hike on the high plateaus of the Vercors.
On the ridges of Rocher de Séguret, Roche Rousse and Pierre Blanche, you are sure to encounter deer, ibex and, with a bit of luck, marmots.
Most of the hike is off the marked trails, so be sure to use the GPX track as everything looks the same.
This hike is difficult due to its elevation gain (950m) and is very strenuous.

Description of the walk

Park after the Pré Râteau forest hut. Alternatively, you can continue to the trail junction, where there is a car park large enough for 4 to 5 cars.
(S/E) Otherwise, head to this crossroads.

(1) Take the path heading due east into the coniferous forest and follow it to the trail junction mentioned at elevation 1544.

(2) Be very careful as the path descends gently towards the bottom of the valley on the left. Follow this north-east facing path.

(3) Join the^GR® 91, follow it to the left heading due north for about 200 metres, and you will come to a crossroads.
Leave the^GR® 91 and turn right towards the Fontaine du Playe. Pass by the fountain, continue up the slope, cross a scree slope and join the Pas de Berrièves trail.

(4) Turn right and you will soon reach the pass.

(5) Just behind the Lorraine cross, leave the trail that descends to the Balcons Est trail. Take the steep grassy slope towards the ridges and the Rocher de Séguret (2051m). Once on the ridges, the view is breathtaking, both to the east towards the Alps and to the west towards the Vercors.

(6) Continue along the ridge heading south, taking great care as you walk along the eastern cliffs, which are very steep. Keep walking south and pass Roche Rousse.

(7) Continue in the same direction along the ridge until you reach Pas de La Posterle and then the summit of Pierre Blanche.

(8) Then reach Pas de la Ville via a very faint path.

(9) Turn right towards Jasse de la Chau in a westerly direction. Head towards the signpost.

(10) Turn right again onto the^GR® 91 and follow it for about 300 metres until you reach another crossroads.
Turn left onto this path on your left, which is barely visible, and follow it west-northwest. Cross the old^GR® trail. The path becomes more and more visible. Pass in front of the ruins of the old Jasse de la Chau.

(11) The path winds through a forest of small conifers, then runs along the small limestone cliff of Roche Ceinturée to reach the initial crossroads.

(2) Head due west along the morning's path, which takes you back to the tarmac road and the car park (S/E).

It is important to be aware that, for more than two hours, you will be walking with your ankles tilted to the same side, as there is no path at the top and you will be walking directly on the slope.
The route often does not allow you to take the right direction, especially since the vegetation has grown a lot in 2024 due to heavy rainfall and has obscured the possible passages.
But my main question is ethical: should we really be sharing routes on the internet that cross a nature reserve, where human presence should be kept to a minimum?

A superb, wild hike, just the way I like them.
The route is excellent. I lost track due to a lack of connection after the Playe fountain, but quickly found it again.
Superb view of the ridges, I loved the hidden arch between the Seguret rock and the red rock and the view of the Grand Veymont and Mont Aiguille just behind, pure bliss.
For me, one of the most beautiful hikes.

Thanks to the author, who's the best 👍👍👍
Gilles.

I really enjoyed this hike despite strong easterly winds and clouds that sometimes obscured the surroundings. There were ibex and chamois along the route, but no marmots.
I missed a few turns, but it wasn't a big deal as I was able to find the trail again.

Very beautiful hike, but we missed point 2, a small path that descends and is difficult to spot, so we hiked from the town to Pas de Berrieve. Still very good, with ibexes to see and beautiful views of the eastern Vercors. Highly recommended.

A very beautiful hike for experienced hikers.
Most of the hike is off the marked trails, so be sure to take the GPS route...

A very beautiful hike. Wild on the ridges and steep slopes. Twenty-five ibex and chamois. Perfect GPS tracking. In summary, we will return on a day with good weather, as we had fog on the ridges, but discovering the ibex emerging was enjoyable and fun. Thank you to the author for sharing this.

Easy parking at pc1513 on the Pré Râteau/Charbonnières forest road.
No problem with the right GPS track, a little more difficult in the scree (3 on the map), but it remains very intuitive when examining the terrain.
The route along the ridge is fairly clear, and again, it's easy to follow the terrain, alternating between grassy plateaus and sharp limestone pavement.
The ibex were there as expected on the Séguret and Roche Rousse side, with a herd of males on one side and females with their young on the other.
The return via the old Jasse de la Chau and the path that follows is pleasant and wild.
A very beautiful hike for experienced walkers, covering approximately 900 metres of elevation gain and nearly 15 kilometres.
