Cascata del Carlone is small (6 meter) but very scenic waterfall southwest of Bobbio in the region Emilia-Romagna, Italy.
From Bobbio drive to San Cristoforo, the road is quite narrow. There is no official parking in the village but near the trailhead you can park your car along the road (gps 44.749536, 9.347985). The walk takes appr 20 minutes (1 kilometer). I am not sure if there are signs.
There is also a trail from Moglia, that trail leads into the valley of the river Carlone. You have to follow the river until you reach Cascata del Carlone. This walk takes appr. 2 kilometer.
