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.
For the ancient Italic peoples it was a sacred river. On the shores, they erected sanctuaries such as the Demetra and Teano one.
Mount Massico with its 813 meters is the highest relief of the mountain range which starts from the slopes of the Roccamonfina volcano and reaches the Tyrrhenian Sea.
The peak of Mount Miletto is reflecting in its placid waters where they come from.
It rises from Lake Matese and in the first part of its way, it is characterised by cascades and differences in heights.
On its shores violets grew, and this is why the Greeks called it Clanis. The River Clanis rises on Mounts Tifatini.
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.
