The loop itinerary starts from Domodossola and includes discovering the rural hamlets of the lower Bognanco Valley. The history of human settlements on the Piedmont strip tells the collective adventure of small rural communities constantly engaged in an arduous struggle against the roughness and harshness of the mountains. It is a fascinating story because it is so far removed from us, and it skilfully shapes the land by creating possibilities for life in an environment dominated by vertical coordinates.
