The Valle Cavanata Nature Reserve is a protected area of exceptional natural value located in the eastern part of the Grado lagoon. Once used as a fishing valley, it is now a wetland of international importance (Ramsar Site) dedicated to biodiversity conservation. The heart of the reserve is a vast brackish lagoon surrounded by reed beds and hygrophilous woods, which serves as a refuge and resting area for thousands of migratory birds, including the famous pink flamingos and numerous species of ducks. Accessible via flat paths and cycle paths, the reserve offers several observation huts for birdwatching, allowing you to immerse yourself in a silence broken only by the calls of the fauna, just a few kilometers from the sea.
