Cabin A. Bonnet

Cabane A. Bonnet sits at 1,265m in the Hautes-Alpes, serving as a base for approaches to Mont Viso and traverses in the upper Guil Valley. The hut lies in rough terrain on the Italian border. Reach it from Aiguilles via the GR54 long-distance route, a 4–5 hour hike gaining 700m. The final approach crosses steep, exposed ground—scrambling skills help. Winter access is unreliable; check conditions locally before attempting the route November through April.
The cabin is basic and small, sleeping around 12 people on bunk beds. It has flush toilets, a rarity at this elevation, and a small communal room with a wood stove. There is no guardian (unmanned refuge), so bring your own food and water, or collect water from the nearby Torrent du Viso. The hut operates year-round but is genuinely isolated; summer is the only practical season for most visitors.
Contact the Maison de la Montagne in Guillestre or the local commune office in Aiguilles for current access conditions and key collection. Expect to be self-sufficient once you arrive. Bring a stove, fuel, and provisions for your stay. The hut is free to use, but respect it as a shared mountain resource.
