From Malghera (1964m) a well-marked track leads to the bridge over the Malghera stream. After the bridge, a level trail is signposted. Follow the trail to Grasse di Pedruna (1921m). At a crossroads, clearly signposted, follow directions towards Alpe Guinzana (1934m) through conifer woods. At another signposted crossroads, the service track for the pasture is indicated. Follow the track down to where it meets another track. The signs here label the other track as the way to Alpe Piana (1883m). Follow the signs along the track to Carette (1775m) and, at a crossroads, take the other track to the Carette high pasture, as indicated. Follow this track all the way to the pasture. From there a trail is marked. It climbs initially, then, following an old military bridleway, it levels out at above 2100m of altitude. The trail then enters Valtellina, providing the walker with stunning views of the valley, and of the slopes opposite, dotted with May pastures and, towering above them, the peaks of the Alpine foothills, gradually declining towards the plain. Continue past Alpe Salina (2174m) and climb to the freezing Lake Schiazzera (2392m), then head down along the bridleway, past nearby Alpe Schiazzera (2106m) and the Schiazzera hut (2079m).

Western Grosina valley runs along an east-west axis, from Malghera to Fusino, where it joins the main Grosina valley. From here, having walked the length of the lower reservoir, the road begins to climb as the flanks of the mountain become extremely steep, right up to where the huts lie scattered around the pastures at Dosso (1270m). Here the road becomes a mere track, and winds its way round the southern protuberance of Mount Alpisella and into the Western valley, well above the course of the deeply embanked western Roasco. The characteristic shape of the gorge at the lower part of the stream’s course can be clearly observed here. It is deep, carved from the mountain sides that are so close together that they overlap. To the right as you go up is the ridge that links Mount Alpisella to Mount Sasso Campana, separating Western Grosina valley from the Avedo valley. The fields fall away steeply towards the east. The slopes opposite are the sheer, harsh, lower slopes of Mount Dosso Campesello. Only upon reaching the hamlet at Dossa (1350m) does the walker encounter a group of alder trees where the slopes become less steep. Piana valley: a broad, long valley that extends south between the Sassumero Peak (2782m) and the peaks of Campesello (2384m), Cornin (2775m) and Campiano (2768m) that look over the Adda valley above Grossotto and Vervio. At the top of the valley stands the Gandi Rosse peak (2830m). Beyond to the south west lies the Poschiavo valley (Switzerland) and to the south, the northern flank of Mount Masuccio (2816m), above Tirano.
