Camposecco Plateau, Regional Natural Park Monti Simbruini is located in Lazio, Italy. The Monti Simbruini regional natural park is a protected natural area among the largest natural reserves and parks in the Lazio Region, with peaks reaching and exceeding 2100 meters. The name "Simbruini" derives from the Latin subbribus elocution, translatable with "Under the Rains". Already the ancient Latins, in fact, noticed the abundance of rainfall in this area, in some years even double the regional average.
