Wurzen Pass, Mountain pass between Arnoldstein and Kranjska Gora, Austria Slovenia.

Wurzen Pass is a mountain pass over the Karawanks between Radendorf in Carinthia, Austria, and Kranjska Gora in Slovenia, reaching 1,073 m. The paved road, B109 on the Austrian side and R201 on the Slovenian side, runs across the lower slope of a steep forested mountain, with a low concrete barrier along the curve and a cluster of small flat-roofed buildings beside the road. It has numerous curves and grades of up to 18 percent, with an emergency escape lane in the lowest hairpin.

A paved road was first built in 1734, making this crossing a key trade route between Carinthia and Trieste. The location later became strategically important after the Second World War when new borders reshaped Europe.

The pass is named after the nearby village of Podkoren, called Wurzen in German. Until Slovenia joined the EU on 1 May 2004, customs controls operated at the border; passport checks with police checkpoints ended on 21 December 2007, when Slovenia entered the Schengen Area.

This route offers an alternative to the toll tunnel and connects directly to Lake Faaker See and Villach. Drive carefully, as the curves and steep grades demand full attention.

The bunker museum occupies the 1.14-hectare site of the former Sperrkompanie WURZEN/73, reopened in August 2005 after the bunkers were decommissioned in 2002. Among the exhibits is a T-34 tank completely encased in concrete, alongside tank turrets, machine guns and a patrol boat of the Sperr-Regiment Donau. Since 2015 visitors can ride in a retired Saurer/Steyr SPzA1 armoured personnel carrier on certain days.
