Description of the walk

Park at the Col de la Charmette car park, which can be reached via Proveysieux and Pomarey (D105).
Take the road to the Chalet de la Charmette.

(S/E) At the Chalet, just above the car park, look for the two distinct tracks that start there. Take the one on the right, which climbs the steep ramp of the Pas de l'Âne.

(1) Just after this, you will come to a junction where you can either:
- towards the Hurtières gorge on the left,
- towards the Cols de la Vache on the right.
Take the second option on the right until you come to a small dip in the path where you will find another intersection.

(2) A wooden sign on a tree indicates that the Col de la Petite Vache is straight ahead. In fact, you need to turn left. The track leads, via a series of small climbs and flat sections, to the Col de la Grande Vache.
From here, the landscape opens up spectacularly onto magnificent mountain pastures.

(3) Descend to the Col de la Sure, clearly visible below.

(4) Climb up just opposite to tackle the beautiful ascent of the Grande Sure. The path is relatively well marked and cairns mark the route to the top. After climbing the shoulder above the Col de la Sure, you will reach grassy and stony slopes.

(5) Turn left to reach a sort of pass marked by deep craters near the ridges. Then follow the ridge southwards to reach the summit of the Grande Sure.

(6) Descend from the summit via the same route to the Col de la Sure.

(4) Follow the sign for Cul de Lampe downhill to the left.

(7) Before Cul de Lampe, take the path on the right to reach the Col de la Charmille.

(8) Ignore the path opposite and the one that descends into the valley you have just come from. Take the path on the right, which climbs gently to the Col de la Petite Vache.

(9) Turn east to enter the Génieux forest. The track is easy to follow. You will soon come to the intersection of the two passes you encountered on the way up.

(2) Follow the same route as on the way up to return to the car park at the Col de la Charmette (S/E).

The signposting between points 7 and 9 is very approximate, so it is best to follow the GPS coordinates.
The hike could be classified as difficult as there are a few tricky sections on the final climb to La Grande Sure. These could cause difficulties for children or people who are not very sure-footed.
Apart from these two points, the landscape is magnificent and we really enjoyed the wild valley on the loop towards the Col de la Petite Vache.

No network coverage from the Col de la Charmette.
Nevertheless, we were able to reach the Grande Sure. The return journey was via the two Vache passes.
14 June, herds taken up to summer pastures.

A very nice walk with panoramic views all the way along and a variety of different viewpoints.
There was still snow for more than 1km at the start, but it was quite doable in hiking boots. We'll be doing it again next season to see it in a different light!

A very fine outing, the main attraction being the viewpoint at the top of the GRANDE SURE. Superb! The rest of the route is just as interesting because of the variety of landscapes. No particular difficulty, perhaps a lack of markings between points 4 and 7 and then between points 7 and 8, but the GPS route saves us a bit when we have it. I agree with the previous comments, there's quite a lot of climbing up to the cross and then sometimes you find yourself alone in the world at the end of the circuit. I recommend it!

A very nice but fairly busy hike up to Grande Sure.
The return via the Col des Charmilles and the Col de la Petite Vache is much quieter.

Hi, I did this walk on a foggy day and couldn't see the landscape. So I'll have to do it again! The route is easy because it is level all the way. The route is well signposted except for the junction at the Col de la Petite Vache, which I missed. Only the GPS application helped me find it. At the summit, the path is blocked by a metal chain, but I got past it. The bad weather kept the crowds away, but otherwise I think there are a lot of people, given the proximity of Grenoble. I came across Chamonix and photography61000 flowers for want of a panorama! I recommend walking sticks. Thank you for this hike.

Magnificent hike with 360° panoramic views from the summit of Grande Sûre. Even Mont Blanc in the distance behind the clouds was visible. A gîte is being built at the foot of the mountain.
What a breath of fresh air!

très beau circuit!
I've often done the summit with a return via the Goulet d'Hurtiere, but via the Col de la Charmille and the Petite Vache, it's more original and varied!
on the other hand, it's not an easy route to the col de la Charmille
from the junction with the cul de la Lampe turn right and walk up three quarters of the grassy corridor. from time to time there are yellow marks on the stones which are often hidden by the grass.
Towards the top, the path veers left and enters the forest; it becomes obvious and you soon reach the pass!
It's a shame there's no sign indicating that you're at the Col de la Petite Vache and pointing the way back to the Col de la Charmette! But I know that the Parc de la Chartreuse isn't up to speed on the signposting of alternative routes! Otherwise, thank you for this beautiful and easy route!
