Between 1953 and 1955 the Italian electricity company ENEL built a hydro-electric dam on the River Tiber, very close to the confluence with the Farfa stream. After this dam was built the water levels started to rise and the surrounding areas were then subject to flooding. As a result, a kind of “lake” was formed, stretching over approximately 300 hectares, which is now a stopping off point for many birds during their migration. The Nazzano Tevere-Farfa Regional Nature Reserve offers visitors a particularly precious natural resource, with the 700 hectares covering a wide variety of environments: from rivers to cultivated fields, reed beds to various kinds of woods. Each offers glimpses of characteristic vegetation and different animals. Nature trails and observation huts can be found along the banks of the Tiber, where you can observe the Park’s aquatic life. Meanwhile, the River Museum (Museo del Fiume) and the Museum of the Night (Museo della Notte) give visitors a deeper understanding of the local ecosystem. All these services mean that you can spend a day in contact with nature, and if you want to get a different view, the "Airone" and "Martin Pescatore" boats run along the River Path (Sentiero del Fiume).
