Leave the Hut (1829 m) and climb to the San Marco pass (1992 m) by the old muletrack (the historical Via Priula) and then go down into Valtellina - for about 150 m - along the road that leads to Morbegno. Now follow the path on the right and cross the northern slope of the “Pizzo delle Segade” peak, until to reach a short ridge, soon interrupted by the narrow “Bocchetta d'Orta” notch.

From Benigni Hut (2222 m) go down to the underlying grassy dell and to the steep rocky couloir, that you follow carefully, especially in the case of humid climate or after storms or sudden snowfalls. When you reach its base, continue along the mountainside, arriving quickly at Salmurano Pass (2017 m) from where the artificial lake of Pescegallo is clearly visible. Continue on the ridge up to a plain then turn right and - following a mountainside path - you arrive near the M. Avaro, where you cross the path n° 109.
Starting from Gromo, go up to the Boario village and continue on the road that leads to "Spiazzi" for about 1.5 km. Arrived at a hairpin (just before - on the left - you passed a grocery store) take Roccolo street (on the left) and, after a few meters, a forest road and path n° 313 (about 1070 m) begins.
Starting from the garage of “Autolinee SAB” bus lines, placed on the left at the beginning of Valbondione (870 m), climb through the woods towards "Salvasecca" farmhouse. Leave it on the left and continue the ascent until you meet a forest road that you have to follow for a certain distance. The realization of such road has modified, in part, the old route. It is important to pay attention to the white-red signs (especially downhill) to follow the path correctly.
