Les Grands Moulins via the normal route and return via the ridges

From Val Pelouse, the ascent of Les Grands Moulins (2,495 m) offers hikers a varied and magnificent route. This summit is the penultimate rocky bastion at the northern end of the Belledonne mountain range.
At the summit of Les Grands Moulins, the 360° panorama is breathtaking. To the south, Belledonne; to the west, Chartreuse and Vercors; to the north, the Chambéry cluse, Les Bauges and Les Aravis; to the east, Lauzière, Beaufortain, Vanoise and, in the background, the majestic Mont Blanc.

Description of the walk

Access from the start: from the village of Arvillard, follow the road to the former Val Pelouse ski resort and park in the large car park at the end of the road.
NB. Closed for a time following a landslide, the Val Pelouse forest road is now open to traffic again.

(S/E) Take the wide tarmac road for about 100 metres, which branches off to the right at the end of the car park. After a left-hand bend, it opens out onto a meadow and leads to a first junction with a signpost for "Val Pelouse 1720m".

(1) Turn right towards Les Grands Moulins and walk up the meadow for about 200 metres, heading towards the edge of the woods, until you reach the second fork with the signpost "Val Pelouse 1740 m".

(2) Turn right into the forest, heading towards "Les Grands Moulins". A good balcony path crosses a wooded area and then, at the edge of the woods, the Grand Charnier, the Pic du Frêne and the Grand Miceau set the scene for the day. It then crosses a wide valley and winds its way through beautiful meadows as it approaches the Refuge de la Perrière.

(3) At the fork leading to the nearby Refuge de la Perrière, stay on the path and continue straight ahead to the next crossroads called "La Perrière" (directional signpost).

(4) Leave the path that climbs left to Col de la Perrière and continue towards Grands Moulins. The path gradually climbs until it forks with the path that leads to Col d'Arpingon.

(5) Take the path on the left that climbs up the southern ridge of Les Grands Moulins.
NB: the direction for Grands Moulins is not indicated on the signs in place (placed on the ground) but is indicated by text and an arrow painted in yellow on a rock lying in the grass.
From there, the slope becomes much steeper. After half an hour's walk, you will reach a small pass that opens up onto the Maurienne valley and the surrounding mountains.

(6) It's another good half hour's walk before you reach the very rocky summit of Grands Moulins, whose secondary summit is marked by a large cairn.

(7) To descend, take the same route as on the way up to the "La Perrière" intersection.

(4) Turn right and climb for about twenty minutes to reach the Col de la Perrière (signpost).

(8) Leave the path that leads to the Gargoton springs and continue on the left (north) to easily reach the magnificent grassy ridge of the Grande Montagne d'Arvillard. At the end of the ridge, a disused hut marks the start of the descent.

(9) Take the wide path on the left, which descends gently down the slope and leads to the meadow you climbed at the start of the hike, bringing you back to the "Val Pelouse 1720m" junction.

(1) From there, follow the same route as on the way up to reach the car park in 5 minutes (S/E).

Notes

The route is well marked, either by directional posts at strategic intersections, by yellow markings on the ground (somewhat faded), or by a few cairns in rocky areas.

Although the slope of the south ridge is steep (between (5) and (7)), it does not present any particular difficulties. The switchbacks remain well marked despite some damage caused by shortcuts taken during the descent.
However, caution is still advised, especially on the descent, where stones have an unfortunate tendency to roll underfoot!

The Refuge de la Perrière: this former alpine chalet has been converted into a refuge (unmanned). A low bench can accommodate 18 people (mattresses and blankets are available), dry toilets have been installed about 50 metres away, water is available from a fountain on the right-hand side and heating is provided by a wood-burning stove.

Worth a visit

Val Pelouse

This alpine pasture where herds used to graze, known as the "Grande Montagne", was transformed into a snow stadium in 1969. It was then renamed "Val Pelouse".
At its peak, the resort was supported by a road with guaranteed winter viability, a power line, a water supply, three ski lifts, a reception chalet and car parks.
However, difficulties soon arose: visitor numbers were too irregular and insufficient, the weather was unpredictable, and the management costs were too high for the inter-municipal syndicate of La Rochette and Arvillard, which had initiated the project.
The resort ceased operations for good in 1986.

A magnificent hike, especially at this time of year with the autumn colours and the first snows. The climb up the great mountain of Arvillard to the Col de Perriére is superb and easy. However, I had to turn back on the ascent of the Grands Moulins via the north face because the snow made the path dangerous and difficult to see. So I rejoined the classic path to the Grands Moulins. The reward is at the summit, with a sumptuous 360° view.
I met a hiker who had climbed up the north face. He told me that he had had a lot of difficulty making the ascent, that it was dangerous with the snow, but that he was too far along to turn back.
I will do this hike again in summer so that I can follow the suggested route.
Thanks to the author.

I started the hike around 7:30 a.m. and was able to see some of the peaks of the Chartreuse: the Lances de Mallissard, the Granier, the Dent de Crolles in the distance...
I missed the turnoff for Les Grands Moulins, so I climbed up to La Pointe de la Frèche (2,230 metres).
No regrets, I had time and the view from this pass was really worth it...
I descended to the sign indicating "Sous les Grands Moulins" (2,113 metres) before tackling the climb, which was very steep in places. I enjoyed views of the Maurienne valley before continuing on to the very rocky summit of Les Grands Moulins (2,4995 metres).
It took me a little over 3 hours from the Val Pelouse car park. I took a 45-minute break to admire the landscape and chat with three other hikers. I took some photos with the elf... View of Mont Blanc from the summit.
On the way down, I came face to face with a somewhat impressive ibex, but it didn't seem bothered by my presence at all. Return to La Perrière (1,850 m) before climbing to the pass of the same name, at 2,003 metres.
Stopped for a bite to eat before following the trail back to the Val Pelouse car park.
Beautiful views of the Grands Moulins during the descent.
In total, 13 km, 1,130 metres of elevation gain and 7½ hours, including a good hour and a half break.

The low number of visitors at around 8 a.m. increased significantly as the day progressed. It is necessary to set off early to avoid the crowds. The beauty of the hike explains its popularity.

watch out for the Val Pelouse 1740 sign hidden by spruce trees!
you can quickly set off on the ridge trail!
otherwise, it's a beautiful route and a lovely return trip via the Col de la Perrière!

The forest road is open again following repairs. Access to Les Grands Moulins from the refuge is not very pleasant (involving walking over rough terrain), but the view is superb, with numerous friendly ibexes as an added bonus. Don't miss the fork at point 5, where a sign further up indicates another path via the Col de la Frêche, which is not marked thereafter.

Parking at the barrier blocking the landslide: the verges are clear and can accommodate several dozen vehicles. I was the third person to arrive at 7.30 a.m. and there were eight vehicles when I returned. Leave the turning area for vehicles clear opposite the start of the forest path (metal barriers)
Climb up the forest path to Val Pelouse, then take the ridge path to the summit. You'll need to use your hands on the last section, but it's quite fun and easy to find.
Very beautiful panorama at the summit, with even a nice windbreak wall and a welcoming gnome.
The descent is steep at first, then becomes easier.
The ascent took me just under 4 hours and the walk took 6 hours and 40 minutes in total.
A very beautiful and fairly easy hike, except for the steeper section just before the summit.

Hello,

For your information:
I visited the area today to explore another route: the road leading to Val Pelouse is closed for an indefinite period (according to the sign) above La Vibillarde, just after a hairpin bend. You should follow a (very well-marked) trail that passes by the Chalets de la Grande-Montagne. This adds about 3 km to the route (6 km if you include the return leg) and an elevation gain of about 450 m.
See the route below: click here

NB: it is also possible to continue on foot along the road, but this takes longer.

Best regards

Surprisingly, for a somewhat difficult hike, there were a lot of people. The hike is great, varied, with magnificent views. It's very easy to find your way.

A very good route in every respect: description consistent with the signposting; beautiful scenery; 360° view from the summit.
And as a bonus, on this day there was beautiful autumn sunshine, which was very welcome on this open route. Shortly before arriving at the car park, we saw two deer and their fawns.
Shoes with "stone guards" were appreciated...
Thank you for this beautiful route!

a wonderful discovery, quite a strenuous climb, very steep and south-facing. The ibex were still there, what chaos at the top of the Grands Moulins, and of course a magical view
a great hike to do, perfect for avoiding the heat. Remember to bring water
thank you
