Season
1 July to 30 September 2026 per the chamonix.com trail page, tied to the La Flegere cable car operating period and 'subject to favorable snow and weather conditions'. Snow lingers on the upper trail into early July — carry traction and check conditions then. Outside the window the lift is closed and the trail at 2,352 m is snowbound: this is not a winter or spring hike.
