The Acquacheta is the most important tributary of the Montone and before reaching S. Benedetto in Alpe it makes a leap of over 70 metres into the homonymous waterfall. The waterfall, described by Dante in the XVI Canto of the Inferno, can only be reached by means of an excursion of a couple of hours that goes up the valley reaching, just above the waterfall, the suggestive Piana dei Romiti with the ruins of the ancient village.
