Klosterneuburg - Vienna - Schönau - Haslau - Scharndorf - Petronell-Carnuntum
Route description:
You start this stage in Klosterneuburg and follow the Donaustrasse (street) to the Nordbrücke (bridge). Here, you change to the other bank and enjoy the beautiful Vienna promenade. In between, you dine at one of the cozy Viennese cafés and enjoy a mélange and a piece of Sacher Torte.
At the central tank farm in Lobau, you turn left onto Lobgrundstrasse (road) where you ride along a long bend to the right. Then you go straight for a short while, still on the Lobgrundstrasse, until turning left at the second right bend. Then you leave the nearby Danube River bank and pass through the untouched Danube wetlands until you see a bridge to your left, which you cross.
Shortly before Schönau the road branches off to the east. After about 7 km, you reach a small industrial park. From there, you continue south. Alternatively, you can turn left and visit picturesque Orth Castle. It is open nearly year round and offers guided walks through the Danube wetlands. You take the ferry over the Danube, then leave the river bank and pass through Haslau.
After a short time, you encounter the B9. There is a bike path along its south side, which you follow for about 4 km. This leads you south to Scharndorf and from there further to the east. You pass through the remains of the Heidentor (a Roman gate) and finally reach Petronell-Carnuntum. The second part of the town’s name (Carnuntum) refers to Ancient Roman fortifications which are in the immediate vicinity and whose ruins can be visited (open-air museum).
