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.
It rises at the foot of Mounts Trebulani, at 86 meters above sea level, in the territory of Calvi Risorta.
For the ancient Italic peoples it was a sacred river. On the shores, they erected sanctuaries such as the Demetra and Teano one.
It rises from Lake Matese and in the first part of its way, it is characterised by cascades and differences in heights.
