Villach (slovenian: Beljak) is a city in Austria near the slovenian border. It is a big one station on the most direct connection between Germany and Kranj and Ljubljana in Slovenia and the Croatian coast. (For example most of the numerous people that go for holydays to the croatian coast pass here.)
South
To the south there is a motorway going through the Karawanken Tunnel over to Jesenice (german: Aßling) in Slovenia. Apart from that there is also the old road over the pass.
