The final leg in Bulgaria cuts through the Balkan Mountains via the Shipka Pass, with dense forests and dramatic cliffs.

UNESCO World Heritage Sites accessible from the route: Ljubljana's Jože Plečnik works, Plitvice Lakes (60 km detour), Stećci medieval tombstones in Bosnia (far detour), Gamzigrad-Romuliana (near Zaječar), and the Rila Monastery (close to route). Each offers a glimpse into the region's layered history. Local commerce thrives at roadside stands selling honey, rakia, and artisan cheeses. In Serbia, stop for ćevapi and burek; in Bulgaria, try banitsa and yogurt.
