The Via Decia trail measures a total of 95 km and is divided into five stages. It starts at the Chapel of S. Cuore di Corna (Darfo) in Valle Camonica, today the memorial for the Gleno victims. Passing by Lake Moro and the village of Angolo Terme, it climbs into Valle di Scalve following the ancient “Via del Ferro”. Here it reaches all four of its municipalities: Colere, Vilminore, Schilpario and Azzone. Finally, it returns to its starting point via Mazzunno and Gorzone. If the first stage involves a certain difference in height, necessary to reach the average altitude of the villages in the valley (between 1000 and 1200 m asl approximately), the following stages proceed in up and downs almost never difficult, and are therefore suitable for all those who are moderately trained for trekking in a mountain environment. The route is almost entirely on paths and dirt roads, with very few stretches on asphalt. Frequent are the stretches of the route within the woods of which Valle di Scalve is largely covered. This characteristic makes the itinerary particularly suitable for the summer period.

The stage cards contain the technical data (length, altitude profile, difference in height, approximate duration), as well as the GPX sheet and an analytical description of the trail. Everyone can in any case adapt the walk, breaking it up according to personal or group needs.
