With a surface of over 1500 square kilometers, the limestone massif of Matese stretches between Molise and Campania and falls within the territory of four provinces.

For the ancient Italic peoples it was a sacred river. On the shores, they erected sanctuaries such as the Demetra and Teano one.

On its shores violets grew, and this is why the Greeks called it Clanis. The River Clanis rises on Mounts Tifatini.

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

Although its name derives from the Oscan word tifata, which means holm oak, Mount Tifata is largely barren, except for the woods surrounding the northern side.

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.
