Towards the Pas des Bachassons
Mont Aiguille
Le Grand and Le Petit Veymont
Ibex next to the Montaveilla hut

Description of the walk

Once you have passed the village of Saint-Michel-les-Portes, continue along the road until you reach the car park just before the tree-top adventure park.

(S/E) The route starts on a good road that is open to vehicles but prohibited to motor vehicles. Continue until you reach the adventure course.

(1) Leave the Mont Aiguille trail on your left and continue straight ahead along the right bank of the Ruisseau des Pellas.
The road becomes a trail and the slope becomes slightly steeper. If you are visiting between mid-May and mid-June, keep an eye out on both sides of the trail for lady's slipper orchids. After a few switchbacks, continue climbing through the forest. The trail now climbs into a valley that gradually narrows. Cross the scree. Reach the Pas des Bachassons, a small trail that winds through a narrow passage along a trickle of water.

(2) Enjoy the fountain. Look for a trail that branches off to the left on hilly terrain. There is a wide view of the high plateaus, the Grand Veymont and Mont Aiguille. After 5 minutes, the trail descends. You will see the notch of the Pas de la Selle. Reach it.

(3) Begin the descent towards the Col de l'Aupet to get as close as possible to Mont Aiguille.

(4) From this point, the views of Mont Aiguille are quite spectacular.
After the Col de l'Aupet, reach a crossroads.

(5) Turn left downhill to join the uphill trail at the Pard Aventure crossroads.

(1) Follow the same route back to the car park (S/E).

Notes

There is a spring at the Bachassons fountain and a hut just after the pass (drinking water except in heavy rain)

This route passes through a protected area, which may be subject to special regulations:

Worth a visit

Lady's slipper orchids are a protected species and must not be picked.
This hike is recommended in late spring (mid-May to mid-June) because the meadows are in full bloom and magnificent. Bring a pair of binoculars because chamois, marmots and ibex are common in this area.

Great route! There were lots of people when we arrived at the hollowed-out tree trunks serving as drinking troughs. Normal for Ascension Day. Water, flowers including lady's slipper orchids, ibex and even shy chamois. We made the round trip to Grand Veymont. It's easily done, an 8.5-hour hike with breaks.

great route, I pushed on to the Roman quarries, 1 hour there and back, well worth it, very busy but normal for a beautiful Ascension weekend, and a beautiful herd of ibexes when I arrived at the Pass.

A beautiful loop with magnificent landscapes, and I was lucky enough to see around fifty ibexes when I arrived at the hut facing Mont Aiguille. It was magical! 😍
However, the descent through the forest, in a storm and rain, was very muddy and slippery... to be avoided in wet weather!

Hike completed with crampons in exceptional conditions. The trail was snow-covered (spring conditions, end of season) and I think it would have been difficult to cross the Pas des Bachassons without the right equipment (old powder snow in some places). Be careful, some parts of the route are quite unstable (Ravin des Serres, Pas de la Selle) and I witnessed several rock falls.
Apart from these few points to watch out for, this hike is one of the most beautiful I have had the chance to do in the Grenoble area. I didn't meet anyone in five hours of walking.

A very beautiful hike!
We did it in very mixed weather (a few showers), with some beautiful views between the clouds, especially of Mont Aiguille, which was magnificent!
The descent was a bit muddy, but passable.
One point to note for navigation: when you reach the pass, the trail fades and becomes a little harder to follow for a few dozen metres, so don't miss the fork on the left. The rest of the route is easy to follow, with no major difficulties despite the steep climb in places.
There are lots of ibexes, which are not very shy, and a few marmots on the upper part.

First and foremost, remember to download the Visiorando map before setting off, as there is no mobile phone reception.
The hike began in cool, foggy conditions, which accompanied us throughout the climb to the plateau and the Pas des Bachassons. This is where the map and GPS tracking came in handy, as there are no real trails, especially in the fog.
But around 1 p.m., the fog lifted to reveal beautiful sunshine that lit up the magnificent landscape, the wild plateau, the panorama, Mont Aiguille, Grand Veymont... to name just the most famous sights.
In short: a beautiful day

We completed this hike in five hours, stopping for a picnic. The route map was very useful for finding the trail on the high plateau (which is not very well marked) and for taking the right path towards the Col de l'Aupet on the descent from the Pas de la Selle.

What a climb up to the Pas des Bachassons! There were quite a few people at the top, but the view of the Veymonts is truly beautiful. The descent down the scree slope isn't very easy on the knees, but the breathtaking view of Mont Aiguille makes up for it.
did it on 11 August on a hot day.

I just got back from this walk. There's a lot of snow at the moment, and some parts are dangerous because you can't see the path. For me, GPS is essential. Without my watch with the Visorando route (loaded onto Garmin), I'd still be there. The scenery is breathtaking even in the fog, and the falling snow was magical against the landscape. I did it in the opposite direction and I think that's better at this time of year because before you reach the plateau at the end of the climb (in the normal direction), there's a lot of slippery snow and the trail isn't visible. The advantage of doing it the other way round is that I just had to pretend I had a sledge under my bum and the descent was great. To sum up, this hike is really beautiful.

A beautiful hike in a wild setting.
Fairly steady climb to the Pas des Bachassons with a few scree slopes.
We had a picnic near the cairn at the summit of Montaveilla: breathtaking views of the immense Hauts Plateaux, the Grand Veymont (shrouded in clouds that day) and Mont Aiguille.
On the way down, we didn't go via the Col de l'Aupet but via the Rocher de la Piche, which was easy going through a beautiful forest.

In short, a magnificent circuit with a very wild atmosphere!

A beautiful route
The climb to the Pas des Bachassons is particularly beautiful
The passage between the Pas des Bachassons and the Pas de la Selle is very poorly signposted (as is usual in the park!) but no problem with the Visorando app
Very beautiful view below Mont Aiguille towards the Col de l'Aupet
The descent from the pass to the car park is unpleasant

Very nice hike, thank you polo381.

A few points about the route:

  • The scree slopes are quite long on the way up (from the Pas des Bachassons), but it's even worse (and more unstable) on the way down (from the Pas de la Selle). Remember to wear good shoes, as usual in the mountains, but it will be less forgiving if you forget.
  • You'll need to cross a few dry river beds, especially on the way up. In my opinion, it's best to avoid this route the day after heavy rain.
  • There are almost no markings for the Pas des Bachassons at the Col de l'Aupet and very few signs along the entire route. Take a good map (or follow the route on the app ) and follow the description.

one small comment about the route: the route passes along a path that no longer seems to exist, 800m before reaching the Pas des Bachassons. The path (indicated by the markings and OSM) now remains in the stream bed.

A long and beautiful hike, like an orienteering game, in search of huts (shepherds’ or hikers’) and precious springs on the Vercors High Plateaus. Fabulous scenery guaranteed. The highlight, undoubtedly the most beautiful natural site on the Hauts Plateaux, is the Plaine de la Queyrie, where I’d love to be reincarnated as a marmot, with its carved tree and its stunning Roman quarry.

To be done outside the snowy season.Return facing the imposing block formed by Mont Aiguille. CAUTION! The scree slope and Pas du Fouillet between points (3) and (5) are currently closed (July 2025). At point (3), continue straight ahead to reach the Pas des Bachassons via the Serres and Maupas ravines, point (6), from where you can reach the Cabane des Aiguillettes, point (6), for a picnic. Then, you will need to return to the Pas des Bachassons to continue the hike.

The tour of Mont Aiguille remains a classic, but to appreciate this "ocean liner", what could be better than gaining some height? The view is not only of Mont Aiguille, as from the summit of Goutaroux you have a 360° view: from Grenoble to Trièves, as far as Dévoluy on one side. From the Vercors ridges to the Chartreuse on the other side.

⚑Departure from Gresse-en-Vercors (Isère)
This walk, the route of which (fully signposted with red and yellow markers) is largely shaded, is particularly pleasant in hot weather. It is strongly advised against undertaking this walk in winter, as the first section runs alongside the Brisou stream on hillsides that are very steep in places. Furthermore, some streams, which are dry in summer, may not be crossable in winter. This is not a family walk suitable for young children!
