The "Foce" is a gully located along the western side of Pizzo Tre Vescovi and leads to the bottom of Val di Panico, that is a glacial valley. The canyon is divided into two branches, right and left, that at some point converge. After a descent of 12 meters you can admire a a majestic rocky area; you can continue and descend for about 65 meters; on the right there's the cascade of "crows" , that is approximately 68/70 meters deep. The trail is moderately difficult.

Due to the earthquake occurred in 2016, the area can't be crossed.
