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.
