The Alpine Marian Path has two routes: the Western Route, from Piantedo to Tirano, 90 km, and the Eastern Route from Bormio to Tirano, 70 km, which is the route you are currently seeing.
Before starting the Path, remember to download the Credential from the official website, the "pilgrim’s passport", a document that certifies the completion of the Alpine Marian Path through a series of stamps that certify, for the various stages, the pilgrim’s passage. Upon presenting the Credential at the last stage, at the Madonna of Tirano Sanctuary, the Testimonium (certificate of pilgrimage completion) will be issued by the Rector of the Madonna of Tirano Sanctuary.
