Drive past Domodossola heading north and continue until the junction for Val Formazza. Pass through the villages of Crodo and Baceno until reaching Premia. Continue beyond the town center to the hamlet of San Rocco, parking near an outdoor event and festival area.

Follow the signs for trail G10 towards Busin di Sopra / Alpe Groppo. The trail ascends the left bank of the gorge; it is marked but rarely used, featuring steep sections and stone steps. Pass the Bochi alpine pasture at an elevation of 930 m and continue just beyond to approximately 1000 m. Here, at a rock face, a faint path breaks off, traversing mid-slope to the south. Follow this mostly flat path past two huts (located roughly 20 meters lower down), then through a characteristic pass over a semi-horizontal rock slab with carved steps. The path then gently climbs mid-slope through the forest and partly along wide ledges until reaching another small hut at 1120 m. From here, climb further toward the now obvious gorge to a horizontal ledge at 1170 m. Descend via a 30-meter rappel off a tree, landing on a flat rock platform directly above a 40-meter waterfall.

The main pitch, approximately 100 meters long, is split into 3 pitches (fractionated into 3 sections). Due to the proximity of the active quarry (and its heavy blasting and potential falling debris on the lower section), descending this canyon is strictly recommended on Saturdays and Sundays only.

Reach the quarry road adjacent to the final waterfall and walk back to the parking area.
