The Riserva Naturale Tevere-Farfa is a protected wetland area formed by the construction of the Nazzano dam on the Tiber River. It serves as one of the most important migratory bird stations in central Italy, characterized by marshy vegetation, willow forests, and reed beds. The reserve covers approximately 650 hectares, integrating aquatic and riparian ecosystems. It functions as a critical sanctuary for species such as the grey heron, the great crested grebe, and the marsh harrier. Visitors can explore a network of pedestrian trails and observation hides designed for birdwatching. The Nazzano lake portion provides a habitat for various freshwater fish species and rare amphibians. The reserve is managed by the Lazio regional park system to preserve the biodiversity of the Tiber valley floor. Educational facilities and a visitor center are integrated within the park boundaries.
