In the Campanian Apennines, in the province of Benevento, the Valley Vitulanese extends to the slopes of the Taburno Camposauro massif, which it encircles amphitheatrically.

The Telesina Valley, in the north and north west of Taburno which it separates from the Matese mounts, extends in the central-western part of the Samnium, crossed by the river Calore and by the stream Titerno.

The Caudine Valley, between the province of Avellino and Benevento, falls for the most part in the area of the latter.
