This historic trail follows an ancient military mule track built along the slopes of Monte Scale to guard the Stelvio Pass road. Now fully restored, it winds through mountain pine forests, old fortifications, and spectacular viewpoints over the Braulio Valley. Along the way, you'll encounter the remains of military buildings, an interrupted tunnel, and a natural terrace overlooking the curves of the Stelvio Pass.

Also known as Cameraccia, this cave dedicated to the edelweiss is located at 2,500 meters above sea level at the foot of Mount Sobretta. For centuries, it served as a refuge for shepherds transhumance between the Camonica Valley and the Gavia Pass. Its walls are adorned with hundreds of engravings—recording names, dates, and symbols—some dating back to the 1700s: testimonies of those who lived in the mountains in ancient times.

This quartz quarry is still active and helps give its name to this section of the Bormio 360 route (mineral trail). You can get there from a very steep road going up from Sondalo or going down on simple dirt roads, but be careful in both cases because you might encounter trucks carrying material to or from the quarry to the town.

At the top of a military road that can be traveled without great difficulty we find the top of this relief that surrounds Pian Gembro. Unfortunately the forest covers the view, but you can imagine how it was during the war, also because there are several tunnels with slits dug for the occasion. I do not recommend trying the circular route around the mountain, because the part towards the south was full of fallen trees and difficult to follow.

Historic trenches built during the First World War. It is a duty to pass through this place which tells the story of this territory, to pause even just for a minute for a thought on what once was.
