The Monti Picentini are a mountain range of the Campanian Apennines where you can identify about fifteen peaks, from the highest Monte Cervialto (1809 m) to the lowest Altillo (1430 m)

Already used since the Neanderthals era, as several worked stone tools testimony prove, the Ariano Saddle is the Apennine pass which in correspondence of the plateau of Camporeale, at an altitude of 600 meters, connects the Ufita-Miscano basin to the Cervaro Valley.

The Monti del Partenio, also known as Monti di Avella, are identified by three ridges, organised in east/west directions and separated by deep valleys.

The most impressive mountain of the Picentini takes its name from the deers, numerous in the past but disappeared nowadays. The Picentini is one of the highest mountains in Campania . the Cervialto.

Located in the northern part of the range of Picentini, the Terminio (1806 meters) is only three meters lower than the Cervialto and it dominates the valley of the river Sabato, while it gently decreases towards the valley of Calore Irpino.

50 kilometers long, the Sabato flows in Irpinia area. It starts on the Colle Finestra del Monte Terminio, and close to Altavilla Irpina it marks for a while the border between the provinces of Avellino and Benevento, where it keeps its watercourse. It receives water from some torrents, of Vallone Barra and Fenestrelle (11 km), which passes through the city of Avellino.
