Wurzen Pass (Wurzenpass or Korensko sedlo) is an international mountain pass at an elevation of 1.073m (3,520ft) above the sea level, located on the border of Austria and Slovenia.
Located in the Karawanks mountain range in the Southern Limestone Alps, the road to the summit is paved. It’s called B109 Wurzenpass Straße (in Austria) and Slovenian highway No. 201 (in Slovenia). The road is very curvy and steep, with a maximum grade of 18 percent.
The pass was already in use in the 15th century. It can be very busy, especially in the summer months, as it is one of the most popular border crossings. The pass is 11.2 km long, and links Radendorf (in the Austrian state of Carinthia) and Kranjska Gora (on the Sava Dolinka River in the Upper Carniola region of Slovenia).
