Bivacco Fiorio

Bivacco Fiorio sits at 2,810m on the border between the French Alps and Italy, in the Cottian Alps east of Briançon. Approach from the Vallée de la Guisane via the Lacs de Laramon trail. The hut is 4–5 hours' walk from the Pont de l'Alpe roadhead. Most parties approach from the Italian side via the Val Maira, which reduces hiking time to 3–4 hours from the Preit trailhead. The location makes it a logical base for traversing between France and Italy, or for accessing the peaks around Mont Viso.
The bivacco is a basic mountain shelter with 18 beds in two dormitory rooms. Water comes from a nearby spring; there is no gas stove or kitchen. You bring a sleeping bag and cook on a camping stove—fuel canisters are sometimes available but cannot be relied upon. The hut is usually open June through September, weather permitting. The shelter is managed by volunteers and relies on honesty-box payment rather than advance bookings. Expect cold nights even in summer and minimal protection from wind on exposed sites.
This is a walker's shelter, not a staffed mountain hut. Check conditions and access before setting out; snow can block approaches well into June. The Italian Val Maira approach is faster and more frequently used. Bring all supplies, water treatment tablets, and repair kit.
