This trail is part of an amazing and incredible journey of knowledge possible thanks to small digital devices, deployed along some of the mountain trails in Lombardy that were the dramatic theater of the Great War.

These are the beacons, guides, audio and video that, for the past couple of seasons, have been leading anyone who ventures into these mountains to discover the environment, men and facts of what we have come to identify as the White War.

From Ponte di Legno in the province of Brescia, in the Upper Camonica Valley, you drive to the Gavia Pass and, having passed the pass by a couple of kilometers, you are at Rifugio Berni at 2,541 m, the starting point of this itinerary.Here you can appreciate the monument dedicated to the fallen of the 307th Skiatori Company Monte Ortler and you can also see the ridge that separates the Dosegù Glacier, which is located opposite at the summit of Piz di Vallumbrina, from the Forni Glacier. We must get onto trail 525, where an information panel describes the historical enhancement and digitization project of the itinerary; almost immediately we reach the Gavia Torrent and cross it on a small wooden bridge, reaching the former Rfugio Gavia, wanted by the Brescia CAI in 1899, it was used as the headquarters of the Italian command of the Gavia sector during the Great War.
You continue following trail marker 551, and do not leave it for almost the entire hike, until you reach the Battaglione Skiatori Monte Ortler bivouac, ascend through a typical alpine environment and overlook the Dosegù Valley. You then lose altitude as you reach the stream of the same name and, keeping to the left orographic slope, almost immediately start climbing again having the glacier seracade in front of you.

Bending to the right we face a steep slope, at the foot of the Piz di Vallumbrina characterized by morainic scree, which leads us to a basin in which three small alpine lakes lie, they are what remains of the Vallumbrina vedretta, we skirt the first one we rise again, to the left, among scree and reddish micascist stones. The remnants of Italian military works of the First World Conflict become more and more evident, we return to the middle of the military village of Vallumbrina where, in 1974 the Bivacco Battaglione Skiatori Monte Ortler at 3,122 m was inaugurated. A saddle allows you to pass over the ridge that, among the remains of artillery emplacements, trenches, bays and barbed wire, leads to the summit of Piz di Vallumbrina at 3,222 m. Rock walls and ice, between the 3,594 m high Pizzo Tresero and the 3,678 m high San Matteo peak, the a natural spectacle is one of rare beauty.
