After a short stretch of cycle path we reach the old SS Alemagna, now completely free of traffic thanks to the new fast road system. Down the hairpin bends of the ancient Cavallera, until we touch the river Piave, in Perarolo di Cadore. In soft descent, we reach Longarone, with the looming skeleton of the Vajont dam, at its side. Once we have crossed the Piave and taken a pleasant minor road, we descend to Soverzene, with its enormous underground hydroelectric plant (until 1951, the largest in Europe!). We cross the Piave again and soon reach Ponte nelle Alpi and then Belluno. At this point, the route leaves the watercourses and skirts the slopes of the Belluno Dolomites, touching a myriad of characteristic villages. After Santa Giustina, we cross Cesiomaggiore; finally, in an easy descent, we reach Feltre.
