Lake Bracciano is a body of water of clear volcanic origin. Its circular shape, like that of Lake Marginano and Bolsena, is a logical consequence. The lake, like the whole surrounding area, is protected by the presence of the Regional Natural Park of Bracciano and Martignano which, in the area of Oriolo Romano, also oversees the management of the Monte Raschio beech forest UNESCO site. The presence of beaches and the protection of water make the lake swimming and full of sustainable initiatives such as rowing boats, pedal boats and sailing boats. The use of motor boats is prohibited.
