Giordano Cottur Cycle and Pedestrian Path

Highlight • Cycleway

The route of the old Austro-Hungarian railway today is a fascinating cycle/pedestrian path, named after Giordano Cottur, which starts from the center of the city of Trieste to reach the Slovenian town of Cosina. Completed in 1887, the railway network connected Trieste to Erpelle (Hrpelje), facilitating a lively coming and going of passengers between the eastern Karst, Istria and Trieste. After the Second World War, the railway continued to shuttle between the city and Draga Sant'Elia, the last town before the border. In 1958 the line was abolished and in 1966 the tracks were removed.

Santa Maria di Siaris Church

Highlight • Religious Site

On the slopes of Monte Carso, on the South East side of Val Rosandra, stands the ancient church of Santa Maria di Siaris.

It was built in the 13th century, probably on the ruins of an ancient tower, and according to legend it was built at the behest of Charlemagne, buried in a nearby cave. Originally it must have also included a small monastery (the "monks of Siaris" - also called "monks on the rocks" - appear several times in documents of the following centuries). Over time the church was restored several times, if not completely rebuilt. The most important restoration was probably that of 1647 (the year reported on its architrave). Subsequently, until the end of the 19th century, the church ended up in a state of neglect. The current structure is mainly the result of works carried out during the twentieth century. Today the church is open and can be visited only on the occasion of the (rare) masses that are celebrated there; even the external visit alone makes it a worthy destination for a nice excursion.

In 1300 it was a pilgrimage destination for blasphemers, who had to walk 12 kilometers barefoot for penance.

On the name "Siaris":
There are no convincing etymologies for the toponym "Siaris". According to Cuscito it derives from the Ladin word "serra" (barrage, mountain, ridge), but this is precisely an unconvincing hypothesis. It is interesting that the name "Siaris" has remained almost unchanged over the centuries: in 1330 it is mentioned several times in the form "Seris", which in the course of the fifteenth century changes to "Siaris", a definitive form preserved to this day.

Mario Premuda Hut

Highlight • Mountain Hut

"The refuge was built in 1933 and completely renovated in 1989. It is named after the Trieste mountaineer and speleologist Mario Premuda, who died in 1931 in an accident on the Picco di Mezzodi in the Julian Alps. The hut also houses the climbing school named after the Trieste mountaineer Emilio Comici. The refuge is a popular destination for its cuisine, but does not offer overnight accommodations and is open year-round except in February."

Luca N.
May 4, 2026, Former Gabrio Modugno Station

The former Gabrio Modugno station is the first stop you encounter when ascending the Giordano Cottur cycle path from Trieste. Located in the Altura district, it owes its name to the memory of the Bersaglieri second lieutenant Gabrio Modugno, who fell during the First World War. Originally conceived as a railway stop on the Trieste-Kozina line, the station today has lost its tracks to become a crucial hub for the city's soft mobility. The building, despite having changed function, retains the typical volume of secondary stations from the late nineteenth century. It represents the point where the route definitively leaves the strictly urban context to immerse itself in the greenery of the woods that precede the scenic entrance to Val Rosandra. For many Triestines, Modugno station is the true "point zero" to begin the climb towards the Karst, an equipped resting place where you can catch your breath while admiring the first glimpses of the Gulf from above.

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.

One of the most popular places for trekking enthusiasts in Trieste. It offers numerous routes to reach the waterfall of over 40 m, the heart of the valley, of different lengths and difficulties, from the "Sentiero dell'Amicizia" to the more complex "Via delle Acque"
