a great classic of the Carso Trail, small sections in single track at the limit of gravel for many, but they make the climb crunchy and fun

Beautiful trail, easily manageable even with a gravel bike. It runs along what was the Austro-Hungarian rear during the Great War. An area rich in field hospitals and unfortunately also cemeteries. This route also partly runs along the path of an old railway that served the Austrian rear. Several rest stops, also excellent in the warmer periods because it is well shaded.

Magnificent panoramic trail, be careful because in good weather it is very frequented by pedestrians.

Observation point near a large aqueduct structure. The asphalt road has a notable incline, a little further on there is access to the sage trail.

As you ascend the Strada del Friuli or descend from Prosecco, you'll come across a sharp bend with a breathtaking view of the sea and Trieste. Stop and admire.

The Imperial Road is the 6-7 km route that connects Basovizza to Sežana without detours. From here, numerous dirt roads branch off through the woods to Lipizza, Gropada, and Orlek. Between the Imperial Road and the paved road that leads from Basovizza to the border crossing of the same name, in the Igouza Forest, lies the Josef Ressel Trail, named after the inventor of the propeller, who lived in Trieste in the 19th century and also devoted himself to botany and the forests of the Karst.
