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.

Great trail, a really nice one overall. Some of the sections have suffered a little bit of water erosion, especially take car in the end, where a stream cut a deep channel where the trail used to be.
