The dirt road connects Perriere to the Strada della Collina, which from Saint Vincent and Chatillon leads to the village of Nissod. It is an easy dirt road, with a compact surface and no roughness, suitable for everyone. Along the gully on the Zerbion side, the Zerbion stream flows, which right at the height of the dirt road generates a beautiful waterfall. The mountainside rises like a spectacular and somewhat impressive wall.

In addition to being beautiful to look at, it is very suggestive to pass by with the splashes that reach you. You have to be careful when going downhill with wet pavement.

Beautiful waterfall, with a pool of water at the top. The road, both uphill and downhill, is blocked and can only be reached on foot or by bike. Along this stretch of road there are other very beautiful water jumps.
