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.

While exploring the Trieste Karst, in the heart of the Karst plain, you come across this large, isolated Austro-Hungarian cemetery. It's heartbreaking to see hundreds of gravestones, each obviously corresponding to a person, buried in this almost forgotten place. This is the absurdity of war. It deserves a visit and a prayer.
