The valley of river Montone is characterised by a richly diversified landscape. Along the road that passes through the valley one can notice a slow and progressive change of the land, from mild hills to thickly bushy slopes, up to the highest peaks where rocky formations of the land are covered with fir trees and beeches.
A river runs through this valley: it rises in the Apennines, near Muraglione Pass (907 meters) and windingly flows down hill. It is called Montone when it gets to San Benedetto in Alpe, where it meets river Rio Destro and river Acquacheta. The latter is considered the real pearl of this land: flowing through a parallel valley, it crosses splendid Romiti plain and forms beautiful Acquacheta waterfalls, making this area one of the most attractive natural resorts of this stretch of the Apennines.
The course of Acquacheta river was probably silted up by a landslide that diverted the original flow south-eastwards. The naturally born beauty of Acquacheta waterfall has a seventy-meter drop and is 35 meters wide; it is situated 5 kilometers away from Mount Lavane spring (1214 meters).
      The valley of river Montone comprises the towns of Portico/San Benedetto, Rocca San Casciano, Dovadola and Castrocaro.
Portico di Romagna, an intact medieval village, is situated at the confluence of river Fosso dell'Olmo and river Montone. San Benedetto in Alpe rises at the feet of Muraglione Pass. The history of this village, that belongs to the Foreste Casentinesi, Monte Falterona e Campigna National Park, is bound to neighbouring Benedictine Abbey, one of the oldest religious buildings of this strech of the Apennines. The land around Portico and San Benedetto is included in the Foreste Casentinesi National Park.
Rocca San Casciano, situated at mid-height in the valley of river Monotone, is very popular for its traditional Festa dei Falò (Bonfire Feast), the antique magic ritual that bids the winter farewell and welcomes the spring with fires floating on the river. Moreover, the history of this town is densely scattered with crucial events, and Rocca's historical importance is mirrored in its beautiful artistic heritage.
      Probably Dovadola has been called after the two fords (guado), Ponte dell'Annunziata and Ponte della Badia, that one necessarily has to cross to get to the village. Its soil is rich in mineral waters and truffles. Castrocaro, the most famous spa of Romagna, is historically bound to Terra del Sole, an intact Renaissance village.
