Alpe Son

Highlight • Settlement

Following the trail markers, you walk along a beautiful stretch of the ancient mule track, still intact in many parts, before briefly rejoining a dirt road, only to return almost immediately to a footpath that crosses a landslide area. As you head deeper into the Torreggio valley, you reach the alpine meadows of Alpe Son at 1364 meters. Here, you leave the path to Rifugio Bosio and turn left towards Piasci.

After crossing the bridge over the Torreggio stream, the trail climbs steadily along a ridge and leads to Piasci at 1700 meters, an alpine pasture dotted with mostly renovated stone huts. From here, the view opens wide, offering a sweeping panorama across much of the Valmalenco valley.

Rifugio Bosio Galli

Highlight • Mountain Hut

The Bosio Galli Refuge is a welcoming structure located at an altitude of 2,086 meters in the splendid Airale Valley in Valmalenco. It is the ideal starting point for more or less demanding excursions, such as the lakes (Zana, Arcoglio, Cassandra) and the mountain pastures (Zana, Mastabbia). Furthermore, it is an arrival and departure stage of the Alta Via della Valmalenco and of the Sentiero Roma. The cycle path that starts from Chiesa in Valmalenco is also beautiful.

Rifugio Bosio and the Torreggio Stream

Highlight • Mountain Hut

The Bosio Refuge is located in the municipality of Torre di Santa Maria, in the province of Sondrio. It is near the very suggestive Torreggio stream. Reachable both on foot and by bicycle, the refuge is a partner of BikeBernina and MalencoBike. It offers catering and overnight accommodation. I recommend that you book in advance.

Alpe di Piasci and Rifugio Cometti

Highlight • Mountain Hut

Alpe di Piasci is a rather large maggengo that dominates a meadowy basin. Located at an altitude of 1720 meters, it offers a panoramic view of the head of Valmalenco, with the Pizzi Roseg, Scerscen, Bernina, Argient and Palù, as well as towards the Sasso Nero.

It is a starting point for excursions to other refuges such as the Desio refuge and the Bosio refuge. Furthermore, it is also possible to reach Alpe di Piasci by mountain bike along a route that crosses first-rate natural environments such as larch woods and large clearings. It can also be reached by car, but you must first obtain a transit permit.
