Can you reach it from Aosta or Turin by public transport?
For public transport, it should be noted that the bivouac is not directly connected. You can reach by bus to Champoluc or Saint-Jacques in Val d’Ayas. From there, you need to continue on foot to the Mezzalama or Guide d’Ayas refuges, and from these, start the mountaineering part. There are no bus or cable car connections that take you directly to altitude.
Where to park the car to climb to Bivacco Rossi Volante?
Those traveling by car can park in Saint-Jacques, the last village in Val d’Ayas. From here, the trail to the refuges begins. In the summer months, parking can be crowded, so it's advisable to arrive early in the morning to find a spot. From Saint-Jacques, it takes about two and a half hours to reach the Rifugio Mezzalama.
What is the bivouac like up close?
The bivouac is built of wood and covered with black sheet metal. It has two small square windows and a central door. It is surrounded by a steel railing with a ladder, which makes it easier to spot from afar. There is no running water: the only source is the melting snow. The location is spectacular because the bivouac overlooks one of the highest and wildest areas of Val d’Ayas.
Who owns the Bivacco Rossi Volante?
The bivouac belongs to CAI UGET of Turin. It was designed as a resting point for climbers traversing the four-thousanders on the border between Italy and Switzerland. It is located about a kilometer from the Rifugio Guide d’Ayas and 360 meters higher.
