Bivacco Boerio

Bivacco Boerio sits at 3,089m on the border between Italy and France in the Mont Blanc massif. The hut is reached from the French side via the Vallée Blanche or from Chamonix by ski or foot depending on season. The approach from Chamonix takes 4–5 hours on foot in summer, crossing the Mer de Glace and climbing steep terrain. Winter access requires mountaineering experience and often skis. The hut serves as a base for traversing Mont Blanc, climbing peaks in the Monte Rosa range, or accessing high alpine terrain in the Gran Paradiso region.
Bivacco Boerio is a small, simple refuge with 10 beds in basic dormitory accommodation. There is no guardian and no meals provided—this is a self-service shelter. You bring your own food, stove, and fuel. Water comes from snowmelt or nearby streams. The hut has minimal facilities: a roof, walls, and basic sleeping platforms. It opens year-round but is most reliably accessed June to September. Winter visits require mountaineering competence and avalanche awareness.
Contact the Chamonix mountain guides office or the FFCAM (Fédération Française des Clubs Alpins et de Montagne) for current conditions and access information. There is no formal booking system. Arrive early if you want guaranteed space during July and August. The hut is first-come, first-served. Tell someone your plans before entering the high alpine zone.
