About
Auberge de Bionnassay sits at 2,191m on the north side of Mont-Blanc massif, in the Vallée de Montjoie near Saint-Gervais. The standard approach is from Le Fayet or Les Contamines-Montjoie: follow the GR5 or local trails up the Torrent de Bionnassay valley. Most hikers take 2–2.5 hours from Les Contamines. The hut is also used as a base for climbers tackling Mont-Blanc via the Goûter route, though that approach is more technical. Summer access is straightforward; winter approaches are steeper and require good snow skills.
The hut offers around 60 places in mixed and private rooms. Meals are available—half-board is standard for overnight stays, with breakfast and dinner included. Kitchen facilities exist for self-catering guests. The Auberge operates from mid-June through September, with the busiest period July through August. It closes in winter despite its elevation, as the access route becomes dangerous.
Book directly with the hut during the season—contact details are typically available through alpine hut directories or the FFCAM network. For July and August, reserve at least 4–6 weeks ahead. The hut is popular with both hikers and Mont-Blanc aspirants, so weekend space fills quickly even in shoulder months. Outside summer, verify opening dates before planning.
