Nature Reserve Val Rosandra — ring tour

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. The Rifugio Premuda, known as Italy's lowest mountain hut, serves as a convenient starting point for many trails in the reserve and offers a place to refresh yourself before or after your run. Plan for approximately 1 hour and 6 minutes to complete the loop, depending on your pace and fitness level.

This reserve is a unique geological landscape where the Karst plateau meets the sea, shaped by the Rosandra River, the only surface stream in the Trieste Karst region. Beyond its natural beauty, you can spot the remains of an ancient Roman aqueduct along some paths, adding a historical dimension to your run. The area is also rich in biodiversity, hosting rare plant species and various wildlife, making it a notable destination for those who appreciate both natural and historical significance.
