The Marian Way of the Alps has two routes: the Western Way, from Piantedo to Tirano, 90 km and the Eastern Way from Bormio to Tirano, 70 km, which is the route you are seeing now.
Before you start the Way, remember to download from the official website the Credential, the "pilgrim's passport," a document that certifies the pilgrim's journey along the Marian Way of the Alps through a series of stamps that certify, for the various stages. Upon presentation of the Credential at the last stage, at the Shrine of Our Lady of Tirano, a Testimonium (certification of pilgrimage) will be issued by the Rector of the Shrine of Our Lady of Tirano.
