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 ancients, it was the river of the myth, which gave forgetfulness to whoever drunk its water.

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.

The peak of Mount Miletto is reflecting in its placid waters where they come from.

It rises at the foot of Mounts Trebulani, at 86 meters above sea level, in the territory of Calvi Risorta.

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.
