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.

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.

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.
