Cabin D'Arclosan

Cabane d'Arclosan sits at 1760m in the Tarentaise valley, a working base for climbers and hikers tackling the granite peaks around Mont-Blanc's eastern approaches. The cabin is reached via the Vallée de la Tarentaise; approach from Landry takes 2.5 to 3 hours on foot, gaining roughly 500m through forest and alpine meadow. Access is summer-only and depends on snow conditions—the site is snowbound from November through May.
The cabin operates as a simple mountain shelter rather than a staffed hut. It sleeps 5 people in basic dormitory-style accommodation. There's a wood stove for heating and a kitchen for self-catering; water comes from a local spring. The FFCAM (Fédération Française des Clubs Alpins et de Montagne) manages the cabin. No meals are provided—bring all food, fuel, and supplies. You'll need to be self-sufficient and experienced in alpine conditions.
Access is restricted to members of the FFCAM or affiliated alpine clubs. Non-members can use the hut if accompanied by a member. Book through the FFCAM's Chambéry section well in advance if you're part of a club; contact details are on the FFCAM website. June through September is the operational window. Check conditions before heading out—this is a refuge for climbers, not a tourist shelter, and weather changes fast at this elevation.
