From Santa Caterina Valfurva, drive to the Ponte dell'Alpe on the road leading to Passo Gavia. From here, take trail S519.2, which runs alongside the Alpe stream and winds through the pastures of the homonymous valley. Arrive at Passo dell'Alpe and from here begin the long descent of the Val di Rezzalo. The first section is a path, then a road with a gentler slope, eventually becoming a drivable road. Pass the picturesque dry stone huts of Clevaccio, Merlo, Rozzone, and the barns of Malnivo, until reaching Rifugio La Baita, where you can stop to enjoy the local dishes. The arrival is planned at the Fumero parking lot. For the return, you can take the same route back; otherwise, it is necessary to arrange another car or use call taxis.
From Frontale, there are public line buses.
