The former military mule track "Valscura Barracks - Fremamorta Shelters"

The portion of the route that runs from Lower Lake Valscura to Lake Claus follows the former military mule track that linked Valscura and Fremamorta. The mule track is one of the best-preserved examples of the old military roads that ran through the Valle Gesso, as well as a true masterpiece of engineering. Realized sometime around the very first years of the nineteen hundreds, a decade prior to the start of the second world war, in 1929, it was preventively upgraded by the Dronero Battalion and maintained in perfect condition. Over 10 km long, it never dips below an altitude of 2,000 meters and has a maximum incline of 18%. Portions of the road were skillfully paved with flagstones, still in place today.
