You leave the car in the large parking lot at Wold, from where you can walk on the road until the chapel of S. Antonio, just after which you leave the road to take trail 206, on the left before the bridge (on the opposite bank, the large sign indicating the entrance to the Alta Valsesia Natural Park is clearly visible). Initially, you follow the stream, then climb a long staircase which leads to the Stiga pasture and to the beautiful Pastore Refuge located at the wide expanse of meadows of the Alpe Pile, where you can enjoy a spectacular view of the southern wall of the Monte Rosa (1h).

Alternatively, from the Wold parking lot, you can take the shuttle to the Acqua Bianca square (1450m). From here, follow the signs for the Pastore Refuge - Alpe Pile (trail 207). Start on a comfortable mule track, then turn left after a few minutes onto a staircase that runs alongside the Caldaie del Sesia waterfall, reaching Alpe Fum Bitz. Here, you go down to the left and cross the Sesia on a covered bridge arriving at Alpe Pile.

From there, continue on a mule track that follows the Sesia on the right bank, passing Casera Lunga, and then, just after crossing the Bors stream, turn onto trail 210 that winds up to the left in bends and steps penetrating the Bors valley until the beautiful fully restored Walser village where the Crespi Calderini Refuge is located.
