Lago di Fimon, Natural lake in Vicenza Province, Italy

Lago di Fimon is a natural lake in Vicenza Province situated within the Berici Hills. The water body supports diverse water birds and aquatic plants that thrive in this protected environment.

The lake's shores were settled in the Neolithic, in the early phase of the Square-Mouthed Pottery culture; radiocarbon dating places the remains in the first half of the 4th millennium BC. Excavations found huts with hearths of limestone blocks covered in clay and silt, and a burial of a boy aged ten to twelve, about 200 years older than the huts. The Vicentine naturalist Paolo Lioy pioneered the study of these finds in the 19th century.

The name Fimon comes from flumonis, meaning "great river", because from the surrounding hills the lake once looked like a long watercourse filling the Fimon valleys until the first half of the 15th century. Volunteers of SOS Anfibi Vicenza now protect the common toad, which uses the water as a breeding site.

A path about 4 kilometers long encircles the lake, offering visitors different walking options. Parking areas and refreshment stands are available to make your visit comfortable.

The lake's name comes from flumonis, "great river": from the surrounding heights the elongated basin, which until the first half of the 15th century covered much of the Fimon valleys, looked like a large watercourse. Its bed is only about 2 m deep on average.
