Cascata del Rio Agaro is an awesome unknown waterfall in the Valle Devero (north of Osso) in the region Piedmont/Piemonte, Italy.
From Domodossola drive to Bacena (roas ss659) an there take the exit to Devero. After 3,7 kilometer you will see Cascata del Rio Agaro at the right side of the road. There is no official parking along the road but there is a small pocket in the road where you can stop (gps 46.281040, 8.2937440)
The water of lake Agaro runs to the river Devero and drops down over appr 60 meters at the last part, near the road. Cascata del Rio Agaro is visible from the roadside when looking to the north/northeast. It is even better to park the car and walk up to this beautiful waterfall.
There are more nice waterfalls in Valle Devero like Cascate Devero and Cascate d’Inferno, worthwhile visiting.
