Description of the walk

Departure from the Pont de la Pêche car park at the end of the road. In August, it is often very full, except at dawn, so you may have to drive back down a little.

(S/E) Start at the end of the road.

Red and whiteGR® 55 markings

(1) Take the time to read the information board, which will give you an overview of the route. Then take the fork to the right along the stream, cross a few trickles of water, go over the bridge (concrete pipes) and start climbing. The slope is quite steep in this first part of the route.

(2) After 1 km, ignore the path on your right that climbs towards the Petit Mont Blanc and continue along the wide path.

(3) After another 500 metres, you will arrive at the Refuge du Roc de la Pêche. You can take the time to visit the restored chapel, or save it for your return trip.

(4) Continue for another 800 metres on this gently ascending path, noting the Chapendu sheepfold on your left; the goats may not be far away. Continue and look carefully to your left below, where marmots are happily basking in the sun. It's about 700 metres to the Ritord mountain pasture. You'll make a detour to Ritord on the way back (cheese is heavy!). Stay to the right on the path.

(5) After another 800 metres, leave the path on your right that leads to Col Rouge (a very beautiful off-trail hike). A little further on, leave the well-renovated Mollaret d'en bas chalet on your right, slightly set back from the path. Then the slope becomes steeper and the path winds around a few bends. At around 2350m, after an S-bend, there is a small lake on your left (still frozen in mid-July 2018). 250m further on, on your right and at the foot of the rocky ridge, don't miss the crystal-clear water.

(6) At an altitude of 2,427 metres, leave theGR®55to climb to the right towards the Peclet Polset refuge

End of the red and whiteGR® 55 markings

(7) You will arrive at the Peclet Polset Refuge. Admire the 360° view. There are several hikes to do in the area and opposite. You can find a spot for your picnic, but the view of the lake will make it even better. Leave the refuge by going around it on the right (east) and following the path that leads to Lac Blanc, the glaciers and the Col du Soufre. Descend towards the lake and walk along its eastern shore. The lake is usually white due to the minerals suspended in its waters, but in July 2018, we saw it as blue, emerald, white and cottony with reflections from the snowfields, all within two hours.

(8) Leave the path to the north-east of the lake, off the beaten track, but in a beautiful alpine meadow. When you reach the pass, look for the tracks that lead you back to the path.
Please note that as of early July 2018, the trail has not yet been restored after the winter avalanches and is 'erased' in three or four sections.
After several hairpin bends, you will rejoin the track.

(9) Take the track back to the start.

Red and whiteGR® 55 markings

(10) To shorten the return journey a little, take a mini detour via the Ritord mountain pasture, where you can buy local products (Beaufort, Tomme, Serac, etc.) and chat with the locals about their unique way of life.

(4) Pass by the Chapendu sheepfold again.

(3) Back at the Refuge du Roc de la Pêche, you can either return via the same route you took on the way there or via the route described below.

Alternative return route: leave the red and white markings

Leave the refuge by retracing your steps a little and heading towards the stream (in the direction of Montaimont). The path is well marked and descends steeply with two hairpin bends towards the stream.

(11) Cross the footbridge and enjoy the view. This is the advantage of this alternative route. The trail climbs steeply on the other side to the buildings of Montaimont. A wide path then heads north. Take this path and, a little further on, it descends more steeply, making a few S-bends.

(1) Head to the information board and the nearby car park (S/E).

Standard mountain equipment is essential. High-top boots, hats, sunglasses, walking sticks
Bring water, as it is a long walk.

Worth a visit

Take a look at the surrounding peaks and passes, these will be your next walks!

A family hike along a long trail that climbs gently and leads to a refuge, ideal for a break. Magnificent view. Access to the lake is easy, and on the day we visited it was a milky green colour, perfect for picnics and photos... Lots of marmots to delight the children, and cows on the trail... Very popular, and rightly so

A parish-specific to Brittany route that is very beautiful to do with the family.
The hike is long, but as the path is very wide and easy to walk on, it's no problem.
The scenery is magnificent and varied.
We saw lots of animals, which helped motivate the children to keep going.
There are people on the path, but it's not too bothersome.

this description corresponds exactly to the hike we did on 1 September with a local guide. We climbed up to Lac Blanc via the Sentier des Bergers trail and came back down via the Ricord farm to buy some Beaufort cheese.
in good weather, this hike is very interesting. The Peclet Polset refuge is very welcoming. We had already visited it in September 2001 during our crossing of the Alps from Pralognan, stopping for a meal at this refuge before continuing on to the Col de Chavières and then on to the Orgère refuge.
a very beautiful region to visit and hike in.

I was blown away! The white lake is magnificent.
There were a few people on the way to the refuge, but after that I was almost alone in the world.
There were a few marmots at the fork in the trail, but I didn't see any elsewhere, perhaps due to the heat at this time of year.
I pushed on to the Col du Souffre: this adds nearly 400 metres of fairly intense elevation gain, but it's well worth it! You'll find yourself at the foot of the strange white mountain you can see from the lake (the Roc du Souffre). A lunar landscape and, along the way, a magical view of the Gébroulaz glacier and its two lakes (you have to climb a mound of stones when you reach the gypsum section; the path is marked).
And once you've descended the Col du Souffre, the descent to the lake will seem very easy

A very easy family hike...the monotony of the wide starting trail is offset by the superb views of the surrounding peaks.
However, the access to Lac Blanc, which we took on the way there by reversing the final loop described, is via a small, very accessible climbing path that winds through the middle of the mountain pasture... it's magnificent and you only come across marmots that roll under your feet without being frightened. The arrival at Lac Blanc via the mountain pasture is very pretty.
The passage through the refuge and the long descent bring us back to civilisation...

A beautiful hike in mid-September in good weather. You can't go wrong, it's straight ahead... Lac Blanc is very beautiful, an ideal place for a picnic. As indicated in the description, we saw many marmots.
Once at Lac Blanc, given the good weather and our energy levels, we pushed on to Col du Soufre. The climb is difficult (after the one to the refuge) but the pass and its mineral environment are worth the detour.

The white lake is always a delight, with its milky green colour
To make it a little more challenging, I added
- The Col de Chevrière before reaching the refuge +350m elevation gain +2 hours. Easy trail to the cairn field. After that, the trail is less clear, so follow the cairns carefully. At the end, climb along the edge of a very steep scree slope, with some very steep sections
- The Col du Soufre after the lake +350m +2h climb of medium difficulty, unusual peaks, ibexes as a bonus
Total: 25km, 1500m elevation gain, 9h40
I really enjoyed it
Thank you

marmots are not overly shy, as long as you don't scare them.

This hike is long but not difficult. You should arrive at the Péclet-Polset refuge around midday for a break near the white lake (which is actually blue) located 10 minutes from the refuge. In case of bad weather, the refuge provides shelter and food. At the end of June, you'll encounter more marmots than hikers. A beautiful and fond memory of this hike. We also recommend stopping for a bite to eat at the Repoju refuge near the Prioux car park.

lots of marmots and a few chamois, which is always nice
i preferred to do the final loop in the other direction (the path wasn't marked, so thank you for the trail) by going first to the lake and then to the refuge
this allowed me to let my wife descend the trail at her own pace while I climbed up to the Col de Chaviere (2 hours) and then descended to meet her at the Roc de la Pêche refuge
in the end, it took us both 7 hours and 45 minutes
the lake is pretty but green, with its reflections and grazing cows
i've never liked trails, but this year it's going well
so thank you for the walk

Very beautiful hike. The lake is magnificent. The path after Lac Blanc is not marked, but it is easy enough to follow without too much difficulty. We saw marmots all along the way.
