It is an artificial lake, created in the 1960s to power the electricity station of Capriati al Volturno.

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

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.

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.

For the ancients, it was the river of the myth, which gave forgetfulness to whoever drunk its water.

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.
