The Acquacheta is the most important tributary of the Montone and before reaching S.Benedetto in Alpe it makes a jump of over 70 meters in the homonymous waterfall. The waterfall, described by Dante in the 16th canto of the Inferno, can only be reached with a couple of hours of hiking, going up the valley reaching, just upstream of the waterfall, the suggestive Piana dei Romiti with the ruins of the ancient village.
