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.

Vodna postaja na steni pokopališča v smeri radijskega observatorija. Sicer pa je v centru vasi pri cerkvi še ena vodna postaja s klopcami za počitek pod drevesi.

Small lake with a water level that undergoes significant seasonal variations, surrounded by a route partly on white roads without technical difficulties, and partly on a single-track path with a karst bottom, therefore technically challenging but allowing access to various observation platforms suspended over the lake. To avoid the section with crashes, ups and downs, tight turns and stones sticking out of the ground, it is possible to complete the loop along a small road (always little frequented) slightly further from the lake which therefore takes away some of the magic... I recommend visiting the spring area, truly fascinating.

A panoramic viewpoint with the Great War Museum nearby, a must-see.
