It starts from the quaint village of Agneda (Sondrio) at 1,228 meters above sea level.

In the winter season it is uninhabited, and if the road is not clear of snow it is best to leave the car just before arriving, where a small parking lot can be found. You immediately put on your skis and in a short time reach Agneda, with a beautiful little 15th-century church dedicated to St. Augustine.

Continue to a wide plateau along a forest road that, with a few hairpin bends, leads to the Scais dam. Once past the dam, we skirt the lake of the same name (1,499 m), which remains, ascending, on our right. You follow the route in the direction of the Mambretti hut, but do not reach it, instead joining the summer trail to the Scais houses (1,547 m) and on to the Caronno huts at 1,612 m.
You cross a small wooden bridge on the right and in a southeasterly direction encounter some characteristic rocks that seem to be driven into the ground forming what looks like a large cave.

You now face the most challenging part. It is a steep gully on the right (beware of avalanche risk) that you follow until you reach a bottleneck from which you exit, on the left reaching the ridge (Scaletta pass 2,523 m?). Continue with a diagonal, still to the left and climb up the gully with some challenging sections. Particularly in the last part, before reaching a wide gap, the snow stability conditions should be carefully evaluated.

From here, in a short time you gain the ski-mountaineering destination or to the left, walking up a ridge on easy rocks, the true summit of Pizzo Brunone (2,720 m). For the ski descent, follow the same route as the ascent. The Redorta Peak (3,038 m) and the Scais Peak (3,038 m) with its namesake vedretta are the backdrop.
