It will only take you a few minutes to reach the bivouac from the pass with a slight upward climb northwards
Access from Prailles/Valpelline
In the square in Valpelline take the road that runs along the cemetery and that goes under the hydroelectric power station, and reaches the bridge over the Buthier. Cross the stream and take itinerary 5 as far as Ronchéaz. After the residential area, go up towards Alpe Planes. Take the dirt road that you meet just before Alpe Planes. Leave this dirt road when you come to a sharp bend just after the houses. Cross the stream and go up to Alpe Verney, Alpe Arpisson and Porillon-Alpe Neuve, occasionally crossing over the road. From here, continue along the road until you come to Fouillou. Keep on to the right along itinerary 105, on the plateau near a waterfall (sometimes dry). On the other side of the waterfall a crag leads onto Lac d’Arpisson and then to the mountain pass.
The bivouac is located on the right before the pass.
Equipment: blankets, gas stove.
