Climb to the Col du Barioz via Les Fontaines and Le Charpieux. A technical climb after Les Perrins requires vigilance and some pushing. Please note: Passage after Les Perrins may be blocked during the summer by an electric sheep fence.

The small road of the Chartreuse balconies runs from Saint-Pancrasse to Chapareillan. Once past the Marcieu pass, it is very quiet in terms of car traffic. This is an area exposed to the rising sun (east face), so it is best to drive in the morning in winter and in the evening in summer.
