Report: 27 October 2023

La Chamoniarde mountain conditions report for 27 October 2023
The off-season is well and truly here! The Indian summer seems to be behind us and winter is just around the corner!
The weather over the last 10 days has not been very favourable for mountain activities, but the glaciers (at least at altitude) and the water tables are recovering!
One storm after another. Last night, it snowed down to 1,800m in the Aiguille Rouges and a little higher (1,900- 2,000m) on the other side of the valley. Guess what, the higher you go, the more snow there seems to be!

In the high mountains, there must be quite a lot of fresh snow, with a lot of snow transported by the inevitable wind. Even if there isn't really a window of opportunity in sight (a bit of sunshine this weekend, but it's forecast to be windy), beware of the risk of avalanches up there, even on the classic 'short' routes from the Aiguille du Midi, for example. You'll also need to watch out for fragile snow bridges on the glaciers.

With favourable weather, it is still possible to hike in the valley. You will need to adapt to the snow conditions and stay below around 2,300m. The paths are quickly greasy and slippery at this time of year, so bring poles and good boots, as well as warm clothing. This is no longer trekking season, so it's best to opt for day hikes.
For your information, several trails are currently closed (particularly in the Argentière-Lognan and Chamonix-Plan de l'Aiguille sectors). For more information, click here.

As a reminder, the Aiguille du Midi cable car, the Montenvers train and the Planpraz cable car are open until 5 November (end of school holidays). After that, the Flégère cable car will be open from 6 to 26 November.

La Chamoniarde mountain conditions report for 11 October 2023

We don't have much to update you on compared to last week, except to tell you to make the most of the fine weather and splendid colours before this coming weekend.

Fans of summer granite will still be delighted by the S faces of the Aiguille du Midi, the Tacul satellites, the Chamonix Aiguilles and, for the strong (ski lifts closed), the Envers des Aiguilles, around the Charpoua, the Moine (except the E face) and the Pierre à Joseph, as well as the Aiguilles Rouges (note that several climbing routes are closed on the Brévent by decree).

Snow and mixed: there are still targets around the Le Tour glacier (technical rimaye on the normal route on the Aiguille du Tour), around the Aiguille du Midi (beware of the very technical 3 Monts) and Helbronner. A team climbed Rêve Éphémère on the Grandes Jorasses, with good conditions up to pitch 5, then it got terribly dry. The normal route on Mont Blanc is busy, as are the winter rooms.

Lower down, it's still great for hiking, sport climbing, cycling or any other activity that takes your fancy.

At this time of year, a lot of work is being carried out on the paths and lifts. We would like to remind you that the paths in the Grand Bois and Pré du Rocher sectors are closed. Don't forget to check the regulations page.

For the Toussaint holidays, the following lifts will be open: Aiguille du Midi, Planpraz and the Montenvers train.

The few huts which are still open close on the following dates: Plan de l'Aiguille - 01/11, Les Prés - 28/10, Loriaz - 15/10 and Tré la Tête - 15/10 (extended opening because of the good weather). The footbridge on the Conscrits path is in winter mode.

In the Aosta valley, the Torino hut is open until 31/10 and the Skyway until 5/11 but remember that the Mont Blanc tunnel shuts on 16/10 at 08:00.

Report: 27 September 2023

La Chamoniarde mountain conditions report for 27 September 2023

We are having a beautiful Indian summer. Winter came back for a bit (details in last week's bulletin) but now the sun and mild temperatures are back at all altitudes. 

Most high mountain huts are now without guardians, including the Cosmiques, those on the normal route on Mont Blanc and the Conscrits, which are all in winter mode. Only the Couvercle (until the end of this week), and the Torino are going onto the bitter end. 

This fine spell will please granite climbers who still haven’t had quite enough. South facing rock exposed to the sun has dried pretty well and there are lots of places like this at altitude including: the Charpoua basin, Aiguille du Moine (with the exception of the East face where the rimaye is very tricky), Aiguille de Pierre-Joseph, Envers des Aiguilles, Aiguille du Peigne, S face of the Aiguille du Midi, Tacul satellites etc. 

For those with an appetite for snow or mixed routes there are still a few to be done including: the classics of the Le Tour basin (Aiguille du Tour, Tête Blanche, Petite Fourche), around the Aiguille du Midi (Cosmiques Arête, Pointe Lachenal traverse), around the Helbronner (Entrèves, Marbrées, Dent du Géant).

In spite of the fact that the huts on the normal route on Mont Blanc are closed, conditions have significantly improved thanks to last week's snow fall. Watch out for overcrowded winter rooms. Snow stability also needs to be a serious consideration. There was a partial burial under the shoulder of Mont Blanc du Tacul on Sunday and some glacier snow bridges are fragile. The Tacul has not been re-tracked, nor has the Trois Monts route. 

Lower down the off-season is great for walking sport climbing, cycling etc.

Report: 22 Septmeber 2023

La Chamoniarde mountain conditions report for 22 September 2023
Autumn is coming! It’s snowing high up, variable amounts but lots of wind: watch out for avalanches and sluffs. Be careful on glaciers with tricky crevasses and potentially fragile snow bridges.

Here are the few snow reports we were able to gather today (it was white down to 2400m yesterday morning):

- At the Goûter, there was a lot of SW wind and we recorded 10/15cm with large areas of accumulation. It's all plastered down to the Nid d'Aigle.

- Torino: 20/30 cm fell. The Dent du Géant, Entrèves and the Marbrées are plastered.

- At the Couvercle it’s all white, but the Moine is still doable.

- Cosmiques: 20cm of wind blown snow fell (foehn gusts, but no thunderstorms). The Tacul is loaded! Everything is covered and the old tracks are no longer visible.

- At the Conscrits, not much has fallen; it rained last night and this morning there was 5cm of snow on the terrace.
- The Bérangère is plastered but the rocks are poking out. Mont Tondu has been done, good underfoot on grey ice. The Miages traverse has been done out and back from the Bérangère (too many crevasses on the glacier). The ice at the Col de la Bérangère is all covered up. The hut switches to winter mode on Monday: there's gas, washing-up facilities and a chemical toilet, but no water (stream 50m away). Access will be complicated after the mid-October footpath work as the footbridge will be removed. The mauvais pas will not be crossable.
The Cosmiques and Conscrits huts will be closing this weekend.

In the high mountains, only the refuges on the Mont Blanc normal route, the Couvercle and the Torino remain open.

There are no worries about hiking in the “moyenne montagne". It is now important to be equipped with good shoes and poles: even if the snow has not yet affected these altitudes, some paths can be greasy and wet.

The refuges at Plan de l'Aiguille, Lac Blanc, Loriaz, Des Prés and Moede-Anterne are still open.

As far as lifts are concerned, the Aiguille du Midi cable car, the Montenvers train (as well as the glacier lift for mountaineers) and the Tramway du Mont-Blanc are still operating.

Report: 14 September 2023

La Chamoniarde mountain conditions report for 14 September 2023
Although the temperatures have dropped a notch, the snowfall forecast for this week was actually quite light and didn't really change the conditions in the high mountains. Two to three centimetres of wet snow fell at the Cosmiques, and around ten centimetres above 4000m.

A few more details to add to last week's update

Le Tour: All the “tat” that has built up over the years on the descent from the summit of the Aiguille du Chardonnet has been removed and replaced with bolt/chain belays. The right-hand line (on the descent) allows you to avoid the rimaye of the col Adams Reilly if this is impassable. Not surpisingly there's no information on the state of the ascent routes! The Albert I refuge closes on September 18. 

Mer de Glace / Leschaux: The lower route across the Charpoua glacier is still passable (see photo below), although the glacier is particularly jumbled and regularly hit by rockfalls. Lots of people on the Drus traverse and on the Contamine-Bastien route, which was climbed in good conditions (see the cahier de course).

The rimaye on the Moine normal route is open across the entire width of the face and is starting to be tricky to climb, but it can be done! The same goes for access to the routes on the E face.
Weather permitting, we'll be here until 30 September at the Couvercle refuge! At the Leschaux, on the other hand, it's the last weekend to take advantage of the guarded refuge. 

On the left bank, the end-of-season clean-up has already begun and the Envers des Aiguilles hut will close on 15 September! The Requin hut has been in winter mode since the beginning of the month.

Aiguille du Midi / Glacier du Géant / Helbronner: As we said at the start of this update, there hasn't been that much snow at altitude. So not much has changed in this sector. The Plan de l'Aiguille, Cosmiques and Torino huts remain open! The Grandes Jorasses traverse has been well-travelled, with decent but often “mixed" conditions. The Tronchey arête was also climbed in good conditions. On the other hand, every one is agreed: the descent via the normal route is no longer the stuff of dreams, with almost constant rock falls during the day both in the Whymper couloir and the Planpincieux glacier, which is wide open. 

Mont Blanc via the Goûter: After a short break, the guides from the Chamonix and St Gervais - Les Contamines companies are back on the Mont Blanc normal route. As always, be careful about the timing of the traverse of the Goûter couloir. 

Bassin de Tré-la-Tête: The Conscrits hut is still open but has telephone problems: contact them for the moment by email at This email address is being protected from spambots. You need JavaScript enabled to view it.

Aiguilles Rouges: This is the last weekend to take advantage of the ski lifts at Planpraz/Brévent and La Flégère!

Report: 6 September 2023

La Chamoniarde mountain conditions report for 6 September 2023

The weather seems to be on a yo-yo as summer draws to a close! After last week's cold snap and snow fall the beginning of September has been marked by unusually hot weather for the time of year. The 0°C isotherm is once again soaring above 5000m and rock fall has resumed in the high mountains, particularly on the west face of the Drus, which had been relatively spared since 2011! Although the snow fall has very temporarily improved conditions for the few snow routes that were still being done, things are changing fast and not in a good way. 

Le Tour 
Conditions are fine on the normal route on the Aiguille du Tour. The Col Supérieur du Tour is starting to go black again. Beware of the instability reported and observed near the the Aiguille Purtscheller: it is recommended to go around it low down before heading to the Aiguille du Tour rimaye, which is crossable in the middle on a snow bridge. The Petite Fourche and the Tête Blanche are also doable. 

Argentière & Charpoua

The refuges have not been staffed since September 1 and August 25 respectively. Consequently, there is little information on these sectors.

Talèfre Basin
The normal route on the Aiguille du Moine is still in good condition! It's a bit more complicated for the east face routes, where the rimayes on the Contamine-Labrunie and Aureille-Feutren are opening up more and more. The Nonne-Evêque traverse was busy, as was the Moine ridge on the Verte for the first time in a while! On the latter, the rimaye is fine, but the ridge is quite dry with rock fall in places.


It's all over for the rock on the north face of the Grandes Jorasses. Despite the current heat, it's not dry enough at this time of year. But everything else is good! The west face of the Petites Jorasses and the Aiguille de Leschaux are dry and approaches are still possible for good climbers. All the routes around the refuge are dry too, and the non-glacial approaches are well-suited to this warm end of season weather! And now more than ever: call before going up to make sure the warden hasn't gone for a walk ;) 

Envers des Aiguilles / Requin

There’s plenty of climbing up here! The rimayes are crossable and on the whole everything's being done!


The Tacul satellites are all dry. The classics (Entrèves, Marbrées) are being climbed, with a nice rock fall reported this morning below the Aiguilles Marbrées (see photo below). On the Dent du Géant, we once again have to watch out for rock falls on the approach to the Salle à Manger - which is also very dry. Plenty of people on the normal route on the Dent du Géant, as well as on the traverse of the Rochefort arête, where the conditions were inevitably worthy of a September: fairly dry on the whole, but bullet hard snow/ice in the morning. No info on the Grandes Jorasses traverse, but we'd love to hear from you!

Aiguille du Midi
Even though the recent snow has been good for the arête, it's still quite technical with a good section of ice under the rocks and several crevasses to get round. And it's not going to get any easier. The same goes for the Cosmiques arête: it's dry again and there's a real risk of it collapsing. Although very crevassed at this time of year, the Vallée Blanche traverse is still possible in the early morning for good climbers. The Mont Blanc du Tacul normal route is being climbed in decent conditions, although a few serac falls have crossed the route in recent days. On the Trois Monts route, we're having trouble getting precise feedback on the Maudit. The ramp used to cross the large rimaye on the face collapsed a few weeks ago and a new route has been opened on the far right, under the rocks. However, the passage is very technical, steep and exposed to both seracs and falling rocks.
Plan de l'Aiguille

Another great place to climb in these hot weather conditions! 

Mont Blanc via the Goûter

Conditions had improved very temporarily with the snowfall, but it didn't last! The rock falls were back with a vengeance in the Goûter couloir. There is snow on 2/3 of the spur below the refuge. Above, the conditions are fine, although you still need to be careful when crossing crevasses and snow bridges, which are weakened by the positive temperatures all the way to the summit during the day! 

Bionnassay / Tré-la-Tête

The Durier refuge has been unguarded since yesterday. The approach to the hut has been made tricky by rock falls on the spur: plan to climb early! On the traverse of the Aiguille de Bionnassay, conditions are good with good steps and no ice. Around the Conscrits/Miage, the traverse of the Dômes is in good condition (no ice) with an out-and-back via the Bérangère. Mont Tondu also looks possible!
