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.
