It is elliptical in shape, has an area of 114.5 sq. km, a perimeter of 43 km, a maximum depth of 151 m, and two tiny, beautiful islands, Bisentina and Martana, both rich in Mediterranean vegetation that provides an incredible contrast to the light blue surface, characterizing the lake.
Thanks to a very modern, complex, expensive sewage system, the lake waters are safe for swimming.
Recently, along the shores of Lake Bolsena, numerous, old fishermen’s huts have been transformed into small, characteristic restaurants, where you can enjoy great, fresh, lake-caught, fish-based dishes. For trekking or mountain biking lovers, Lake Bolsena can also be reached by means of a naturalistic, countryside itinerary.
