Waterfall of Valganna, Artificial waterfall in Induno Olona, Italy.

The Waterfall of Valganna is an artificial waterfall in the Valganna valley, in the municipality of Induno Olona. It is fed by one of the three main springs of the Olona river, the branch rising at Alpe Ravetta (618 m). The base lies at 613 m and the drop is 20 m; the caves of the same name are nearby.

The falls were created artificially at the start of the 20th century to make it easier to draw water from the Olona river. They belong to the branch of the Olona that rises at Alpe Ravetta, at 618 m above sea level. The drop measures 20 m, with the base of the falls at 613 m.

Local people connect these falls to the mineral-rich waters of the Olona River, which have shaped the appearance of the rocks over time. The deposits visible on the stone walls give the spot a distinctive character within the valley.

You can reach the site using marked paths that start from a large parking area just past the tunnel on Valganna road. The walk is fairly short with some sections of gentle slopes, making it suitable for people of varying fitness levels.

The falls are fed by the branch of the Olona that rises at Alpe Ravetta (618 m); the base sits at 613 m and the drop measures 20 m. Because the water carries carbonates, travertine is deposited on the rock, which is why locals call them "sorgenti petrificanti", petrifying springs. The caves of the same name lie close by.
