The Vršič Pass at 1,611 metres is the highest road pass in Slovenia and the main connection between the Soča Valley and Kranjska Gora in the north. The road — narrow, steep, and surfaced with cobblestones on some of the older sections — has 50 numbered hairpin bends and is spectacular throughout its length.
The pass is open from approximately May to October; in winter it is closed by snow. Driving it in either direction is an experience in itself. At the summit there are walking trails into the surrounding Julian Alps, including the path to the source of the Soča — a karst spring that emerges in a cave about two hours' walk from the pass. The descent into the Soča Valley offers the first views of the turquoise river far below.
