Embark on the Nature Reserve Val Rosandra — ring tour, a challenging jogging route that takes you through dramatic limestone cliffs and varied terrain. This 4.5-mile (7.3 km) loop features a significant 1069 feet (326 metres) of elevation gain, making it a difficult but rewarding experience for experienced trail runners. As you navigate the rocky paths, you will encounter the impressive 40-meter Supet Falls and dense forests, with glimpses of Mediterranean shrubland and karst heathlands.

To prepare for this demanding route, ensure you wear sturdy trail shoes with good ankle support, as the varied and sometimes rugged terrain requires sure-footedness.

Tips from the Community

Luca N.
May 4, 2026, Val Rosandra

Located behind Trieste, Val Rosandra is a unique nature reserve where the homonymous stream has carved the only deeply incised valley of the Trieste Karst. The landscape is dominated by rugged limestone cliffs, white scree slopes, and vegetation that blends Mediterranean and continental species. Famous for its 36-meter-high waterfall, the valley is a sanctuary of biodiversity and history: it hosts the remains of a 1st-century AD Roman aqueduct and the ancient church of Santa Maria in Siaris. A prime location for Trieste's mountaineering, its cliffs were the school of Emilio Comici. Between arduous trails and views of the Gulf, Val Rosandra represents a concentration of wild nature and millennia-old testimonies, suspended between the Karst plateau and the Adriatic Sea.

Many Italian churches are dedicated to the Virgin Mary and thus bear "SANTA MARIA" (occasionally elevated to "SANTISSIMA") in their name. This church has the suffix "IMMACOLATA," meaning it is dedicated to the Immaculate Conception of the Virgin Mary. This term, which may sound somewhat theoretical and difficult to grasp today, expresses the idea that the Virgin Mary was, from the very beginning, freed by God's grace from the burden of original sin—which every human being otherwise carries. This enabled her to freely answer "yes" when the Archangel later announced to her in Nazareth that she would give birth to the Son of God. In 1854, Pope Pius IX declared this dogma. The feast day commemorating this occasion—and also the patronal feast of this church—which in Catholic liturgy is officially called the "Solemnity of the Immaculate Conception of the Blessed Virgin Mary," is celebrated annually on December 8th.

It is a burial mound that dates back to the Bronze Age, it is one of the most panoramic points of the Karst, with a view that ranges from Istria to the Julian Alps. Beware of vipers in the spring-summer period!
