On August 5th, the ascent to the alpine chapel at 2007 meters in the San Grato Valley
In Issime, a small municipality in the Lys Valley in the Province of Aosta inhabited by a historic Walser community speaking the Töitschu dialect, August 5th is a date that is renewed every year. It is the day of Our Lady of the Snows, celebrated not in the village but at altitude, in the alpine hamlet of Mühnes, at 2007 meters, in the picturesque San Grato Valley.
From the early hours of the morning, residents and hikers ascend the slopes of San Grato to reach the small alpine chapel. The building was constructed as a votive offering by the Chouquer brothers, who survived an avalanche, and consecrated in the 17th century: a sign of devotion that still draws people from Issime and the surrounding areas to walk towards the mountain.
Around 11:00 AM, Holy Mass is celebrated in the alpine chapel. Afterwards, the Pro Loco (local tourist association) distributes the traditional polenta and milk, a simple and iconic mountain dish, while the festival continues in the afternoon with musical accompaniment from the local band. This is not a spectacular event in the tourist sense of the term; it is a true popular festival, where the religious rite, the effort of the climb, and alpine conviviality merge.
The Feast of Our Lady of the Snows in Issime is one of the many celebrations that animate the high-altitude sanctuaries of the Aosta Valley on August 5th. In Mühnes, however, the charm lies in the Walser context: a German-speaking community of ancient alpine origin, whose traditions endure in the mountains of the Lys Valley. An opportunity to discover a less-traveled corner of the region, combining hiking and local culture.
The 2026 edition takes place on Wednesday, August 5th, the fixed date of the commemoration. As every year, residents and hikers ascend the San Grato Valley from the morning to reach the hamlet of Mühnes, at 2007 meters.
Traditional program: Holy Mass in the alpine chapel around 11:00 AM, followed by the distribution of polenta and milk by Pro Loco Issime and musical accompaniment by the band in the afternoon. Specific timing details will be communicated by the Pro Loco in the weeks prior.
General program based on the established tradition of the festival; any variations and detailed times will be communicated by Pro Loco Issime closer to the event.
Issime can be reached by car from the Pont-Saint-Martin motorway exit (A5), going up the Lys Valley along the SR44. The hamlet of Mühnes, at 2007 m, can only be reached on foot with an alpine walk from the valley floor through the San Grato Valley: wear trekking shoes and mountain clothing.
August 5th every year (fixed date). Mass around 11:00 AM, followed by distribution of polenta and milk.
