Perrero – Gran Faetto

Perrero 820 m – Mortaria 1080 m – Colle Clapier 2010 m – Comba del Torno 1585 m – Chasteiran 1509 m – Roreto Chisone 854 m – Gran Faetto 1270 m

A section that is a little long, but of great interest for the abundance of the flora and fauna, the wide pastures of the Muret and especially for the itinerary through the solitary ravine of Bourset, of incomparable beauty. The hardest part of this section is the climb back from Roreto to Gran Faetto, even though it follows a mule track, but it can be eliminated by using a car.
