Description of the walk

Access:
With a high-clearance vehicle => see author's note in the introduction.
From La Grave, take the D1091 towards the Col du Lautaret. Go through the tunnel, then immediately after the tunnel exit, turn right towards the villages of Les Cours and Le Chazelet.
Drive through the village of Le Chazelet, descend, then take the track towards Pic du Mas de la Grave for 6.5 km, ignoring any junctions.
Pass the hamlets of Rivet du Milieu and Rivet de la Cime, the Chalets de la Buffe, then park near the yurts and Chalets de la Grande Buffe.
With a standard vehicle
Park in the car park above Le Chazelet, then walk up the track to the Chalets de la Grande Buffe as described above.
In this case, the total distance of the route increases to 23.5 km with an elevation gain of 1,270 m.
This hike can be done over two days with an overnight stay at the refuge.

(S/E) Take the path that continues on from the track to the foot of the Cabane de la Buffe hill.

(1) Ford the Gâ torrent and then climb north-west up the valley where a stream flows for a distance of 80 m.

(2) Take the path on the left towards Pic du Mas (sign).
The path climbs generally south-west, then turns right to the north-west and, after a long traverse, reaches the broad grassy ridge of the peak.
Our path climbs in stages up steep slopes. With altitude, the landscape becomes arid and mineralised.
After passing along the side of a secondary summit where there is a superb cairn, it descends gently onto a flat section and then begins its ascent of the summit ridge, winding its way discreetly through the slabs of schist. This brings you to the summit, marked by a simple cross.

(3) Return via the same route in reverse to your parking spot (S/E).

Notes

I made a video with the names of the peaks, which shows the route and the atmosphere of the hike.

What can I say about this route?
The route corresponds to the GPS track recording. It deviates at times from the IGN itinerary, following sections of the trail that are not shown on the map. Conversely, some other sections of the trail that are shown on the map no longer exist on the ground.

The summit climb from the slightly exposed secondary summit may impress hikers who are prone to vertigo.
Remember to bring at least one and a half litres of water per person.

Refreshments are available at the Yourte des Bergers.

A very beautiful hike, but in my opinion the route should be revised. The trail starting from Le Chazelet is closed to traffic, which is a good thing! (It is reserved exclusively for authorised persons and alpine farmers).
Admittedly, the approach to the Buffe chalets is a little long, but this is more than compensated for by the beauty of the landscape (especially on the way back, facing La Meige).

A superb hike, thanks in particular to the accurate description and, of course, the beautiful weather.
It is actually 23.5 km long with a 1,400 m elevation gain if you are not travelling in a 4x4.
The last 30 metres to the summit are not suitable for those who suffer from vertigo.

Very beautiful 3000, easy to access from the refuge where we slept, a highly recommended refuge, newly renovated, very good food and a friendly welcome.
Lots of bikes on the trails, a slightly dizzying passage towards the end and a summit platform limited to three or four people maximum. Don't count on having a picnic at the summit.
Superb!

A very beautiful walk, though a bit long, with the first part at the bottom of the valley, followed by a 1,000-metre climb all at once. It's not bad, as it warms you up for the rest of the walk.. However, I wouldn't recommend taking the car to the Pic du Mas de la Grave refuge, as the stone path is really only suitable for 4x4s! So you have to bear in mind that this walk is just under 24 km and takes eight hours... But once you reach the summit, and in fact throughout the entire hike, it's really worth it!!! La Meije, the Emparis plateau, the Aiguilles d'Arves, the Grandes Rousses, and even Mont Blanc in the distance..

Did this hike this weekend.
You can now leave your car in the car park above Le Chazelet, and we booked at the Pic du Mas de la Grave refuge, which is about 5 kilometres further away but certainly much less than if you were to set off from the village...
I saw a car go as far as the Yourte des Bergers, but then again, there was only one and it was more of a 4x4. In my opinion, it's a shame to start from there when the refuge has been completely renovated. Hot showers, spotless toilets, very well insulated, etc.

The highest point is 3,020 metres, not 2,979 metres to be precise, and this is indicated on the map.
The last climb in this mineral desert is quite steep, so you need to be a relatively good walker.
There are vultures everywhere! And fields of edelweiss too, incredible.
At the summit, you can see the south face of Mont Blanc, the Viso in the distance to the south, and closer by, the Étendard and Pic Bayle, the Aiguilles d'Arves and so on. And then there's the Meije, of course, fantastic!

A must-do and, for me, a must-do again.

We did this hike many years ago.

It was necessary to leave the car at Le Chazelet, so it was a long walk to get there.

I did this hike in September 2020.
The hike starts from the village of Le Chazelet. You can no longer drive to the starting point mentioned in the description, which adds a few kilometres to the hike.
So allow for more time.
