It is the second river of Southern Italy due to its volume of water. The Sele (64 km) rises on the north-eastern part of the Monte Plafagone (foothill of the Cervialto), at an altitude of 420 meters, in the district of Caposele.
Its main spring, as the Calore one, feed the Apulian Aqueduct. On its upper reaches in Irpinia area, it receives numerous torrents and valleys. Its tributary is the river Acquabianca (6 km), which rises in the Monti Picentini, crosses the natural oasis Valle della Caccia and which, after a spectacular waterfall, it joins the Sele in the district of Senerchia. The Sele keeps its way southward entering in the Cilento.
