I have always preferred to start from Bocchetto Sessera, on a dirt road to Artignaga or, a few dozen meters below, on the path of smiles.
From Artignaga, depending on the day's plan, many possibilities open up, from a long and tiring tour, in a good sense, to Alpe Balma delle Basse, three buildings painted white under a roof of rocks, then to the nearby hill between Asnass and Punta dello Scaletto, and then to the right on a path that climbs to the hill between Cravile and Bo, then either you descend along the crest to the left to Bocchetto or, with a bit of time and experience, you can go up to the right to Manzo and Bo, obviously you have to question your body and your watch to decide sensibly, hours of walking and altitude difference can become excessive.
But it is already beautiful and satisfying to go up from Artignaga to the Alps of the Bassa, a dozen or so houses in a row, half renovated and half ruins, and then to the hill before Cima delle Guardie and then return via the ridge to Bunom and finally to Bocchetto Sessera
