This sublime section covers the River Danube from Passau to Vienna passing numerous villages, towns, cities, castles, vineyards, forests and much, more. The river cuts its way through a few mountain ranges creating spectacular gorges and loops such as the Schlögener Schlinge between Passau and Linz. The famous baroque Abbeys of Melk and Goettweig mark the borders of the Wachau Valley, which has been a UNESCO World Heritage Site, since 2000. Towns, such as Spitz, Weissenkirchen and Dürnstein have been accredited for their medieval architecture, urban design and surrounding agricultural landscape. The Danube here also flows through the cities of Linz and Vienna.
