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.

You can typically start your journey from the hamlet of Isollaz, which is reached via regional road 45 of the Val d'Ayas from Arnad. Parking is recommended in Isollaz itself.

The best time to visit waterfalls in the Aosta Valley, including those near Arnad, is generally during spring and early summer when snowmelt increases water flow, making the falls more powerful and spectacular.

While specific dog-friendly designations for each waterfall trail are not always available, many natural trails in the Aosta Valley are accessible to dogs, provided they are kept on a leash. It's always best to check local regulations or specific trail information before heading out with your dog, especially in protected areas.
