Tips from the Community

May 4, 2026, Sant Antonio Station

The Sant'Antonio-Moccò station, located along the Giordano Cottur cycle path, represents one of the most panoramic and historically relevant points of the former railway line. Situated at about 250 meters above sea level, this stop served the villages of Sant'Antonio in Bosco and Moccò, connecting the rural communities of the valley directly to the center of Trieste. Today the building, although transformed, remains a visual landmark for those traveling the route. It is precisely near this station that the trail enters the heart of the Val Rosandra: beyond this point, the view dramatically opens up onto the scree slopes and vertical walls, offering one of the most famous vistas of the entire route. The platform, where passengers once waited for steam trains, is now a privileged terrace overlooking the wild nature of the Karst.

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.

Honestly one of the nicest views you'll find in the area, and a great spot to watch the sunset.

Easier than the upper section, a lot less steep, but with some really fun turns through the woods

The view of the Val Rosandra from the old railway line is truly extraordinary.

Spectacular single track that avoids all nearby paved roads. The surface is packed with rocks (S1), requiring caution and good riding skills. When wet, the surface can be quite slippery; just a little caution is all it takes to have fun like a child.
