Snow and wind at altitude, the first frosts, fog in the valley - there’s no doubt it’s Autumn.
It snowed high up at the beginning of the week. We think between 5 and 10cm of snow at 2,300m. There was a dusting at 2,000m but it has already melted. Higher up it’s difficult to estimate the quantity of snow. At the Torino Hut there is about 40cm. What is certain is that it’s all beautifully white. You can get a reasonable idea of conditions thanks to the webcam of Punta Helbronner and for the footpaths the webcams of the Compagnie du Mont Blanc.
The classic snow routes must be possible at the moment but at this time of year they are much more committing, and you will need lots of experience. It’s a long way, the huts are shut, it’s cold and there are no tracks. You may need snow shoes to get around on glaciers.
The Skyway lift and the Torino hut are still open. The shorter classic routes (traverses of the Marbrées and Entrèves and glacier trips) are being done.
It’s certainly possible that mixed routes are in condition, but you will have to go and see as we have no information.
The rock is well plastered even quite low down (Envers des Aiguilles, Plan de l'Aiguille, Argentière basin, Aiguilles Rouges). Rock climbing is therefore concentrated on sunny valley crags. Watch out for fog, seepage and cold fingers. Or go further south.
Quiet footpaths and beautiful autumn colours await you. There are no problems with walking below 2,200 m (warm clothes + gloves + hat needed). Above that height, there is some snow and you will have to equip yourself properly (good shoes + poles).
Remember to consult the list of trails closed for work.
As a reminder, the Montenvers train is the only lift currently open in the Chamonix Valley.
