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.

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 starts in the area of Frosinone from the confluence between the Liri, which first crosses Abruzzo and Lazio, and the Gari, which rises at Cassino and is often called Liri-Garigliano.

It rises from Lake Matese and in the first part of its way, it is characterised by cascades and differences in heights.

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.
