Located just a few kilometers from Duino Castle, in the western sector of the Gorizia Karst, Lake Pietrarossa is one of the pearls of the Regional Natural Reserve shared with the nearby Lake Doberdò. Together with the latter, it represents one of the very rare examples in Europe of a karst lake: a temporary basin that occupies a natural depression called a polje. The charm of this place lies in its changing nature; it is not fed by surface rivers, but by the oscillations of the underground water table. During rainy periods, water emerges from the depths, flooding the plain, while in dry seasons the lake can almost disappear, leaving space for a verdant carpet of reeds and wet meadows. This alternation creates a unique ecosystem where the arid and rocky karst landscape meets a humid area rich in biodiversity, making it a paradise for birdwatching and silent excursions.

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.

Very interesting biotype, one of the few examples in Europe of a karst lake-pond, whose level changes continuously depending on the Vipacco and Isonzo rivers.
