Conditions August 5th 2019

5 August 2019

The trails, in early August, are very busy and conditions are generally good. The most significant variables are related to the weather which, as expected, will worsen from tomorrow night untill thursday. It is therefore recommended to equip yourself and to manage the time of your hikes according to the climatic changes.

For the trails around Chamonix, we remind you that from August 5th to 30th, in addition to the closing of the trails under the Flégère cable car, the lower part of the trail linking the Flégère to Lac Blanc will also be closed. However, Lake Blanc will still be accessible from Chamonix via the Planpraz cable car, taking the Grand Balcon Sud road to La Flégère, then:

  • Index Chairlift (open until August 18) and trail leading to Lac Blanc;
  • Grand Balcon Sud towards the Cheserys lakes, then fork towards Lac Blanc.


In addition, we remind you that it is also possible to reach the Lac Blanc from the Col des Montets, from Tré le Champ (some sections are equipped with through stairs) and from Argentière.
