Description of the walk

(S) (Start point) Park your vehicle at the "Parking des Barnets", on the road to the "Stade de Neige" of Lans en Vercors. Take the large trail in front which leads to the "Refuge des Allières".

(1). Continue straight ahead until you reach a trail crossroad. Follow the trail waymarked with red and white stripes (trail GR91). You reach a second crossroad.

Turn left. (2) A sign indicates "Col de l'Arc". Follow the path waymarked in yellow;after about 10 minutes you head out of the forest and start climbing;after a hairpin bend, you reach the alpine pasture. You then walk almost horizontally up to the "Col de l'Arc".

(3). At the "Col de l'Arc" pass, a sign indicates the different directions. For the "Pic Saint Michel" follow the path on the left, along but at some distance from the ridge. It is waymarked in yellow and with cairns from place to place, and reaches the "Pic Saint Michel" summit without difficulty.

(4) To go down, continue on the trail, still waymarked in yellow. You head North and reach "Combe Oursière".

(5) The path then makes a 90-degree left turn and heads West, goes through the mountain pasture and after a series of switchbacks, heads back to the "Refuge des Allières".

(1). You then take the path back to the parking.

Notes

The Vercors massif has a few watering places. One of them is located on this trail, under the crossroad between the GR91 and the "Col de l'Arc" trail. The water is fresh.

The "Refuge des Allières" offers a pleasant stop, especially when the weather is hot, but it is also open most of the year and welcomes tourists and hikers in a splendid house typical of Vercors.

Please note that the cliffs on the "Vallée de la Gresse" side, namely the East side, are very abrupt, with a steep precipice. If you hike with your children, keep an eye on them and prevent them from venturing close to the cliff's edge. This is also true at the summit of the "Pic Saint Michel".

This route passes through multiple protected areas, which may be subject to special regulations:

Worth a visit

Visit the Vercors plateau and its landmarks, its towns and villages such as Villard de Lans, Saint Nizier du Moucherotte and Autrans, famous for the 1968 Olympics Games.

We did this route today; there’s still plenty of snow along the way – there’s snow almost from start to finish, with about a metre of it towards the end... With good hiking boots and if you’re not afraid of sinking in, it’s still doable and absolutely stunning, with a 360° sea of clouds at the top!
Great hike!

Perfect route, but be careful of snowfields; bring crampons and walking sticks for the descent. There are bivouac sites and small shelters for hikers along the route. Magnificent scenery, very popular with hikers and dogs. Fairly easy hike, but allow 5 hours.

A classic in the area, offering a high-quality and relatively accessible panorama, hence very popular. A good compromise for a half-day hike near Grenoble. Nothing to report.

A lovely walk with beautiful scenery.

Follow the route in the direction indicated by the author. There are many people at the Col de l'Arc, few at Pic St Michel and almost no one on the descent to Combe Oursière.
At the start, at the crossroads shortly after the Allières refuge, we hesitated a little before finding the right GPS track on GR91.
For the descent from Pic St Michel, we followed the route marked by yellow markings on the ground.
Between 5 and 1, we couldn't always find the Visorando GPX track on the ground. So we followed the yellow markings to the Allières refuge. Shortly before the refuge, the descent became much steeper and very rocky for about 200 m... not very easy despite the walking sticks - except for experienced trail runners
At Pic St Michel, you can see the Vercors plateau and the Grenoble plain, and you can see various mountain ranges and peaks

Hi. I walked this today but did so without reading the route sheet first. On reflection the description seems pretty reliable and if you have an IGN map and or a GPS you won't be getting lost. On the descent the path now follows the track shown by the black line to the North of the blue path taken by the author. This misses out the cave.
We went the way described here as it allows more shade in the trees on the first part of the ascent and is a little more easy angled.
Busy route mid summer, no wildlife apart from the Yellow Billed Coughs on the summit. Lots of paraglider pilots out today and a fixed wing glider too.
The refuge at Les Allieres is great, have one of their ice creams; they are amazing.

A hike that starts off gently, continues through the forest and finally climbs quite steeply. The description is accurate. The path is well marked. The reward is at the top with a 360° view. Be careful of loose stones underfoot on the descent. These trails are very popular at this time of year. This may explain the absence of wild animals. Only yellow-billed choughs were present.

It was very busy on Saturday.

A slightly strenuous hike, but the reward awaits you at the summit!
To be done on a perfectly clear day to take full advantage of the view of the surrounding mountains,
And if possible during the week and outside school holidays, for added peace and quiet.

It's a lovely hike, the climb goes very well, you have to take it easy, the view is splendid when you get to the top, it's a feast for the eyes, it's magical. Be careful on the way down, it's slippery, so it's best to be well equipped.

Thanks to Visorandonneur for this track. A lovely hike. A magnificent view from the peak. Mont Blanc and the Ecrins mountain range. A loop completed in 3h30. Please note: On the descent, after Point 4, the current signposting no longer follows the path that passes through the karstic cave at Pic St. Michel, but follows the path that goes off to the left at hill 1853 on the map. Even though the old path has some old beacons ..... and marmots. But watch out for the right turn that is not signposted before you reach the baume des allières. Thanks again.

I advise you to come in the morning around 10/11am and do the circuit in reverse.
Start with the steep slope to reach the peak, so the return journey will be easier on your knees.
A great hike with a breathtaking view!
However, beware of the difficulty rating: "medium level", as this is not a gentle walk.
(You need to be a bit of a sportsman to climb the path to the summit).

We did the ascent the other way round, taking a little longer towards the Combe des Oursières to climb more gradually. It was quite windy at the top, so there were quite a few paragliders.
Thursday was a sports day at Grenoble University, and the students were enjoying themselves too.
