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.
Start from Grassi Hut (1987 m) and follow the southern slopes of the Cima di Camisolo top. Continue following the panoramic “Pian delle Parole” ridge until reach the “bocchetta Alta” notch. Leave on your left the "del Caminetto" equipped path (which leads to the summit of "Pizzo dei Tre Signori" peak) to cross the steep southern slopes of the mountain along a mountainside path (known as "Sentiero dei Solivi" path).
