Val di Peio: Retreating Glaciers and Ancient Spas in the Upper Val di Sole

The Val di Peio is not unknown to mountaineers — the Cevedale and Vioz are classic destinations in the Stelvio Park — but to ordinary tourists driving through the Val di Sole, it appears as an unnecessary detour. That's its main advantage: you can walk on the Careser glacier, visit historic thermal baths, and sleep in a mountain refuge without encountering queues or booking months in advance.

The Careser glacier and climate change

The Careser glacier is one of the most monitored glaciers in Italy for the study of glacial retreat. Since 1900, it has lost over 70% of its surface area. This makes the visit paradoxically urgent and meaningful: climbing to the Rifugio Careser (2,600 meters, also reachable by cable car) and walking along the glacier's edge is an experience that teaches something no book can convey. The refuge is open from June to September and serves mountain dishes at standard Alpine prices.

The Peio spa and historic treatments

At 1,389 meters elevation, the Terme di Peio draws on cold oligomineral springs known since the seventeenth century. The current facility is modern but unobtrusive, integrated into the Alpine landscape. Treatments include thermal baths, mud therapy, and inhalation therapies: prices start at about 20 euros for a single bath, well below the rates of South Tyrolean spas. The village of Peio Fonti, with its stone houses and geraniums on the windowsills, has an authentic scenic quality.

Trails for all levels

The Val di Peio offers trails ranging from flat walks along the Noce stream to technical climbs toward the Vioz (3,645 meters). A mid-level and rarely frequented route leads to the lower Careser lakes, two and a half hours from Peio Fonti with 900 meters of elevation gain: an itinerary that crosses alpine meadows, dwarf pine groves, and, in August, expanses of rare mountain wildflowers. Access to the valley is from Malè, in the Val di Sole, via an 18-kilometer scenic road.
