La Grande Sure from the Chartreuse de Curière

Another way to reach the summit of the Grande Sure. Most hikers from the Grenoble area access it via Proveysieux and the Col de la Charmette. For those coming from the Savoyard hinterland, access via Saint-Laurent-du-Pont and the Chartreuse de Curière is an interesting alternative.
From the start at (5), the route is not very busy.

Description of the walk

From Saint-Laurent-du-Pont, take the road towards Saint-Pierre-de-Chartreuse and after 1 km, take the small forest road towards the Charteuse de Curière.
Park in the large car park 150 m after the last buildings of the convent. Beyond this point, the road is closed to traffic.

(S/E) From the car park, take the beautiful track that starts on the right. This track climbs steadily through the forest to reach the Belvédère de Nonne viewpoint.

(1) From the viewpoint, continue for 100 m to find the signpost for 1200 m, with a cross hidden in the trees. Continue in a south-westerly direction and, after a short descent, the track ends and turns into a rocky path. Stay on the path and you will reach a junction.

(2) Leave the path and take a trail that climbs to the left (steep at first) and continue through the forest until you reach a scree slope. Cross it by following the trail to the left at the foot of the cliff and, once you have left the scree slope, you will reach Cul de Lampe (signpost Alt 1400 m).

(3) Continue climbing through the forest and then into increasingly open terrain until you reach a meadow (signpost 1490 m).

(4) Leave the path that climbs to Col de Charmille on your left and follow the meadow on the right, initially on a flat path. At the end of the meadow, the path climbs gently towards the clearly visible Col de la Sure.

(5) At Col de la Sure, you will rejoin the paths coming from Col de la Charmette and suddenly find yourself in much more company. Take the steep, winding, rocky path on the right. Allow 35 to 40 minutes to reach the summit (panoramic view).

(6) From the summit, descend to Col de la Sure. On the descent, take note of the path you will follow to make a circular route.

(5) From the pass, head left (north-east) towards Col de la Charmille along an almost flat balcony path. Shortly after reaching a more wooded area, you will arrive at Col de la Charmille.

(7) From the pass, turn right onto a dirt path, then a forest track that has been completely destroyed by logging equipment. Descend carefully along this track until you reach an intersection: the "dining room".

(8) Leave the track and take a path on the left. 100 metres further on, ford a stream and continue along a comfortable path until you reach an intersection with a small viewpoint over the Chartreuse de Curière.

(9) Then turn left onto a rocky path with numerous hairpin bends and come out onto a road.

(10) Turn left to quickly return to the car park (S/E).

Notes

To avoid the route along the rough track, from (7) (direction sign) you can descend towards the meadow at (4) and thus rejoin the route from the start of the climb.

Worth a visit

Between (3) and (5), you may see mouflons.

A very beautiful route, even though the weather conditions were not ideal on Tuesday 22 July! Long and demanding but not difficult. I did the hike by following the same route on the way down as I did on the way up.
I would like to point out an error in the display of a municipal by-law prohibiting access to the footbridge on the Cul de la Lampe trail. At a place called La Terrasse at an altitude of 1,340 metres, there are several documents on display: an information note for hikers and a municipal by-law accompanied by a map of the alternative route around the footbridge.
The map of the alternative route confused me. The yellow cross indicating the location ("You are here") is not in the right place, which suggests that you are already on the closed trail when in fact you are 600 m higher up at La Terrasse. A check on the IGN TOP 25 map I had with me confirmed this. On both the outward and return journeys, I met hikers who were just as confused as I was. I was able to confirm that they were not on the closed path.
I don't understand why the sign was placed there. I wrote to the town hall of Saint-Joseph de Rivère, the Coeur de Chartreuse community of municipalities and the PNR to report this error.
The trail between points 2 and 3 is fine.

A good quality circuit that I keep recommending to others because it is physically demanding, technical and varied in terms of the paths taken.

Hike completed on 13/07/25. A pleasant, well-marked route, mostly in the shade, with magnificent mountain pastures. The climb to the Grande Sure is fairly easy, with beautiful views of the Rhône valley and the surrounding mountains. Please note that there are many fallen trees on the way back after the Col de la Charmille before reaching the viewpoint over the Chartreuse.

Hike completed on 7 March 2025 in snowy conditions. Difficult in snow, good physical condition recommended. A few tricky sections before the summit in snow, but nothing impossible. Splendid weather, the route is excellent.

A beautiful and pleasant hike, full of flowers in the meadow between the Col de la Grande Vache and the Col de la Sure.
No difficulty. It's great.

Having already climbed La Grande Sure several times, either via the Goulet d'Hurtière or the Col de la Vache, this longer route offers a different ascent and is pleasant, much less crowded than the others mentioned above (at least up to the Col de la Sure) and offers beautiful views. Magnificent panoramas. The only thing to watch out for is the very last descent on La Curière, which is a very steep and narrow path and requires a little caution. Bring plenty of water as there are no springs. Otherwise, it's great!

A very beautiful hike. The Chemin de la None trail starting from the car park is closed due to tree felling and rock falls. You can start the hike by taking the return route (from the finish to point 7) on the way there and back. The Sentier des Agneaux trail (from points 10 to 9) is steep from the start.
On the way back, it can be tricky going downhill in wet weather. Another possible route is the Petite Vache trail from point 8. Continue along the logging trail until you reach a semi-tarmac road. Turn left onto the forest track which leads directly back to the car park. It's a bit long but safer. You will pass through two tunnels, one of which, the Tunnel des Agneaux, is several hundred metres long and unlit. A torch is essential! Thrills guaranteed!
I did this route on a weekday in early July and only encountered three Forestry Commission officers.

Beautiful hike on varied terrain (woodland, meadows, scree). Very busy after the Col de la Vache pass.

Hello,
Is this hike feasible in winter with snowshoes?
Is it an avalanche zone or is it safe? (At first glance, it doesn't look like it when I look at the slope maps.)

Thanks in advance.

A beautiful and varied route. Magnificent view at the summit. No snow on 18/11/2018, and indeed, crowds at the summit. The hike does not present any particular technical difficulties, but the descent is covered with dead leaves and therefore slippery. The GPS track is sufficient in addition to the signposting.
Thank you for the description.

Do not take beginners
It's a shame that part of the descent has been ruined by forestry machinery

A beautiful morning discovery on the climb up to Col de la Sure, with a detailed and accurate description of the route and the unexpected and peaceful sight of around thirty female chamois and their young crossing the "Prairie" just after "Cul de lampe". A herd of chamois and lines of mouflons moving northwards across the last meadows and scree slopes on the Sure side.
With the route map, the three passes are clearly visible in the relief and reinforced by their respective paths and trails.
Without GPS, the return via the "petite vache" path was a bit scary after the forest logging site at high altitude after the Col des Charmilles: it is possible, on the 8 on the map, that I took the clear path on the left to the beautiful viewpoint on the ridge above Curière, but there were no paths leading down from there, even in a series of zigzags. Even at the end of an earthy drop between a few trees and a ten to fifteen metre cliff that walkers' footsteps had not reached on the hundred metres to the west. Damn!
Back to the familiar valley and resumption of the descent. The path, even though it was a forest path, joined and crossed the stream, following the largely cleared strata on the right-hand side. At the next crossroads, a sign showing disregard for professional ethics points to a path on the left marked "Curière par le chemin des agneaux" (text from memory), which corresponds to the description in 8, 9 and 10. The "tilt" would make sense again on this narrow path clinging to its shady cliff - and not a deadly one.
Thank you.
