Sacra di San Michele Approach (Sentiero dei Principi)

The Sacra di San Michele, a medieval Benedictine abbey clinging to the summit of Monte Pirchiriano at 962 metres above the entrance to the Susa Valley, is the architectural symbol of the Piedmont region and the inspiration for the monastery in Umberto Eco's novel The Name of the Rose. While most visitors drive to the car park near the top, the rewarding way to arrive is on foot from the village of Sant'Ambrogio di Torino on the valley floor, following the historic cobbled mule paths, the Via Crucis and the Sentiero dei Principi, that pilgrims and abbots used for centuries. The trail climbs steeply through chestnut and oak woodland, gaining around 560 metres over roughly 3 kilometres, passing wayside chapels and the ruins of the older Mortera path before emerging at the abbey's monumental entrance. Inside, the great Scalone dei Morti staircase and the Romanesque-Gothic church reward the climb, while the terrace offers a sweeping panorama down the Susa Valley toward Turin and the surrounding Alps. The path is well marked with CAI signage and is on a surface of cobbles, stone steps and woodland dirt that can be slippery when wet, with sustained climbing that makes it a moderate outing despite its modest length. The Sacra also sits on the long-distance Via Francigena and the Cammino di San Michele pilgrim routes, so the approach can be combined with longer walks toward the Val di Susa abbeys. Unlike the high mountains, this trail is walkable for much of the year, best in spring and autumn when temperatures are comfortable and the woodland is colourful; summer is hot on the lower slopes and winter can bring ice on the cobbles. Water and a cafe are available near the abbey but not on the climb, so walkers should carry supplies. Arriving on foot at this thousand-year-old abbey after the same climb made by medieval pilgrims gives the Sacra di San Michele a sense of occasion no car park can match.
