The city of Klagenfurt am Wörthersee (or just ‘Klagenfurt’) stands in the south of Austria, just 15 miles north of the border with Slovenia and equidistant from Innsbruck and Vienna. Visitors who hire a car in Klagenfurt will find that it is surrounded by wooded hills and mountains, the Wörthersee Lake and the Glan River. The shores of this warm-watered Alpine lake are considered Austria’s ‘Monte Carlo’, thanks to its upmarket homes, hotels and restaurants. There’s a large sandy beach and lido. The Glan, in contrast, runs through pretty and unspoilt valleys and passes the picturesque but little-known Burgruine Glanegg Castle.
