The Mont Outheran plateau

From a distance, Mont Outherand looks like a fortress, with several gaps in the limestone walls of the fort.
Near the Col du Mollard, a steep path allows attackers to overcome the fort's defences.

Description of the walk

Park at Le Désert in the large car park of the cross-country ski centre.

(S/E) Ignore the beautiful track heading north and descend towards the stream valley. Cross the Ruisseau de la Chaume stream via the track.

(1) Immediately, leave the path on the right and follow another path that runs alongside the river. Arrive at Les Marots.

(2) Take the barely marked path on the left to walk as close as possible to the river and join a more clearly marked path.

(3) Follow it, continuing to the right, and cross the river via a bridge to rejoin the track.

(4) Continue climbing to the right along the track and reach an intersection 100 metres before the Col du Mollard.

(5) Turn left onto the path, which soon becomes a very steep and winding trail, to cross the cliff. As you climb, cross a fence and emerge onto the plateau to reach the Outherand hut.

(6) Leave the marked trail to the right towards Col du Planet and follow the trail that crosses the plateau from north to south. In the absence of specific landmarks, follow the yellow markings and after a long traverse you will reach the wooden cross.

(7) Return via the same route until you reach the intersection near the bridge.

(4) Continue straight ahead, simply following the track, and return to the car park (S/E).

I am planning to do this hike in the spring with a small group of twelve people. My question: has anyone done this hike recently? Is the descent via Pas du Cuert and Col du Grapillon dangerous? Thank you.

As one of us is prone to vertigo, we opted for this round trip from the Désert d'Entremont to the Croix du Mont Outheran. Although Mont Outheran is not very high, the landscape is superb both on the way up and at the Croix. Le Granier, Chamechaude, the Dent de Crolles, the Bauges and much more: the landscape is well worth the (relative) effort of climbing up to the plateau. The sharp limestone pavements are... well, sharp limestone pavements, but this is the Chartreuse! It is easy to miss a mark on the plateau, but the GPS track is there if you need it to get back on the right path. Thanks to the author for this hike.

I crossed the Outheran on 4 July (ascending via the Pas du Cuert and descending via the Col du Mollard). The Pas du Cuert is not equipped at all and, in the absence of fixed points, there is no possibility of securing yourself. It is technically easy but requires experience and concentration. Any misstep is to be avoided. The descent via the Pas du Cuert would be very tricky. The crossing itself is not difficult. The markings (yellow dots) are clearly visible and easy to follow. There is no risk of getting lost. The plateau is wild and very beautiful. A very beautiful hike far from the crowds.

Crossing the plateau is long and tedious, especially on the return journey. I had thought about descending via the Cuert Pass, but knowing that my son is prone to vertigo, I went to check it out. For me, there was no problem, but I was worried that my son might have a tetany attack, and how would I get him down? Is there a cable, as I heard? There are no markings on the plateau at strategic points, and we found ourselves on the cliffs.

Nice hike, but if I were to do it again, I would take the circular route via the Grapillon Pass to avoid the return trip over the sharp limestone pavement, which isn't very pleasant. On the other hand, the view is superb, despite the overcast sky that day.

Avoid doing this hike when the ground is wet and visibility is poor:
- Much of the route is on sharp limestone pavement (areas of fractured limestone) where it is easy to slip.
- The yellow markings are very good, but if you miss a mark, you can easily get lost in very fractured areas.

Overall, the medium difficulty rating is accurate, and the arrival at the cross is well worth the effort.

Thank you.

It's a bit of a workout in the sense that it's a walk that really puts your ankles to the test, as you're walking on rough rocks most of the time. It's very pretty, a very beautiful walk.
