This itinerary is fully part of cycle-mountaineering due to its difficulty: in addition to the development and the difference in height that should not be underestimated, it includes sections where it is expected to carry the bike on foot or on the shoulders.

You cross the Italian-French border in front of Mount Oronaye, with its 3100 m. You will encounter gentle valleys, wide meadows and severe stony ground along the way, as well as numerous alpine lakes.

The tour starts from the village of Ponte Maira, just above Acceglio. The ring is made up of about two thirds of single trails, one third of dirt tracks and just over 1 km of asphalt.
