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.

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 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.

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)

The Calore (108 km), Irpino to distinguish it from the homonym river of Lucania, finds its sources on the Accellica Mountain in the Picentini chain, in the cities of Montella and Cassano Irpino.
