The ancient high-altitude pilgrimage to the sanctuary
The Pilgrimage to San Besso is one of the oldest and most evocative religious traditions shared between the Aosta Valley and Piedmont. From Cogne, in the province of Aosta, the faithful set off to reach the Sanctuary of San Besso, built under a huge rock at over 2,000 meters, in the Soana Valley. The veneration of the martyr San Besso has united the communities of the two valleys for centuries.
The route from Cogne is reserved for experienced and well-trained hikers: it crosses the Colle dell'Arietta (2,939 m), with sections on snow and passages equipped with fixed ropes. Pilgrims leave the day before and spend the night at the sanctuary, to be present at the celebration the following morning. It is an experience that requires physical preparation and adequate equipment, but which rewards with high-altitude landscapes of rare beauty.
The culmination is the solemn Mass at the sanctuary, followed by the procession with the martyr's statue around the great rock, which tradition holds was the site of his martyrdom. It is a rite that blends popular devotion, alpine identity, and connection with the mountains, experienced by generations of Cogne inhabitants.
The 2026 edition of the Pilgrimage to San Besso is scheduled for August 9th and 10th. Two days of walking and devotion between Cogne and the Sanctuary of San Besso, in the heart of the Alps between the Aosta Valley and Piedmont.
Route reserved for experienced hikers. For participation and overnight stay, contact the Parish of Sant'Orso (+39 340 4856463).
