Once known as Lake of Carinola, it is a volcanic lake at the foot of mount Massico, in the municipality of Falciano del Massico.

For the ancient Italic peoples it was a sacred river. On the shores, they erected sanctuaries such as the Demetra and Teano one.
With a surface of just over a square kilometer, the enchanting Lake of Letino was created at the beginning of the twentieth century in order to feed the hydroelectric power station of Prata Sannita.

Older than Vesuvius. It is among the biggest of Italy, but extinct since fifty thousand years ago. The Roccamonfina volcano rises isolated between the Aurunci Mountains, in Lazio, and in Campania Felix the plain of Garigliano and the Massico massif, separating it from the Tyrrhenian Sea.

It is an artificial lake, created in the 1960s to power the electricity station of Capriati al Volturno.

In the north-east of Campania Felix, separated from the Campania Apennines by the valley of the Medio Volturno, the massif of the Trebulani Mountains rises, also known as the Colli Caprensi.

It is one of the favourite stopping points in the long spring migration from Africa to Central Eastern Europe on the Tyrrhenian route.
