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.
On its shores violets grew, and this is why the Greeks called it Clanis. The River Clanis rises on Mounts Tifatini.
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.
For the ancients, it was the river of the myth, which gave forgetfulness to whoever drunk its water.
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.
It rises from Lake Matese and in the first part of its way, it is characterised by cascades and differences in heights.
The extinct volcano of Roccamonfina is the heart of the park that protects since 1993 a territory of great naturalistic value from Campania Felix up to the border with Lazio. Eleven thousand hectares of volcanic rocks and limestone, streams and lush vegetation, dotted with ancient hamlets keeping alive the imprint of their past and the heritage of their identities.
