It rests in the upper part of Tuscia, not far from the Lake Bolsena. It can be reached very easily from Valentano, following a road crossing the “nothing”: very very rare houses scattered in a bright green valley under a bright blue sky. The only buildings near the lake are two agriturisms, a nice distance from its shores. Lake Mezzano is in the middle of a SIC Area and has black-bass and pike plus other whitefish and “coregoni”. The lake has a no-fishing area (breeding) area. The lake originates the Olpeta, entering the Fiora not far from Farnese. The first part of this river offers pikes while during its way down to the Fiora it looks like a mountain stream.
