Cascata dell'Infernaccio, Waterfall in Lazio, Italy

The Cascata dell'Infernaccio is formed where the Rigo River drops about twenty metres on its way to the Tevere, inside the Gole dell'Infernaccio, one of Lazio's deepest gorges. Iron-based minerals carried by the water leave reddish deposits along the streambed, contrasting with the white of the falling water and the surrounding vegetation.

The waterfall forms where the Rigo River drops about 20 metres on its way to the Tiber, inside the Gole dell'Infernaccio, one of Lazio's deepest gorges. The ravine's name comes from the forbidding terrain. In June 2021 a large rock mass fell from the wall beside the cascade, partly blocking the river and forming a small basin.

The waterfall is nicknamed "La Perla dell'Infernaccio" for its appearance. The Rigo's iron-based minerals tint the rock and water red, contrasting with the white fall and the surrounding green vegetation. The roar of the water dropping about twenty metres is part of the experience.

The route to the waterfall is difficult and not recommended for safety reasons: the cliffs are unstable and a large rock mass fell near the cascade in June 2021, partially blocking the river. There are no marked paths or authorized observation points; do not venture into the gorge.

The waterfall is nicknamed "La Perla dell'Infernaccio". Its jump of about twenty metres is amplified by the noise of the water, and the iron-based minerals carried by the Rigo stain the riverbed reddish, contrasting with the white of the falling water and the green of the surrounding vegetation.
