Klosterneuburg - Vienna - Schönau - Haslau - Scharndorf - Petronell-Carnuntum
Route description:
You start your route in Klosterneuburg and follow Donaustraße to the Nordbrücke. Here you change the riverbank and enjoy the beautiful Vienna riverside promenade. In between, you stop at one of the cozy Viennese cafés and enjoy a melange with a piece of Sacher Torte.
At the central tank depot in the Lobau, turn left and ride along Lobgrundstraße through a long right curve. Then it goes straight for a short distance, still along Lobgrundstraße, until you turn left at the second right curve. You leave the nearby Danube bank and travel through the unspoiled Donau-Auen until you see a bridge on your left to cross over.
Shortly before Schönau, the path branches off to the east. After about seven kilometers, you reach a small industrial area. Here, you continue south. Alternatively, you have the option to turn left here to visit the picturesque Orth Castle. The castle is open almost year-round and offers guided hikes through the Donau-Auen. You cross with the ferry, leave the Danube bank, and pass through Haslau.
After a short time, you reach B9, along whose south side a cycle path runs, which you follow for about four kilometers. This takes you southward to Scharndorf and from there further east. You pass the remains of the Heidentor and finally reach Petronell-Carnuntum. The market town has its secondary name due to a Roman fortress located nearby, whose ruins can be visited in the local Roman district (open-air museum).
