From Zinnergasse station in New Albern, follow the bridge over the Danube Canal. If you are already hungry, you’ll be happy to find the casual fare and outdoor seating of Donauweibchen restaurant right away. Next you’ll witness an impressive piece of infrastructure, by crossing over the Freudenau locks and hydroelectric dam that harness the river. On the other side is a more natural display in the forests, meadows, and ponds of Danube Island. Here the Rundumadum leads through Toter Grund, a nature reserve and nudist bathing area. You can choose to follow the wide, paved path along the shore, or deviate to the island’s interior and find secluded swimming spots.

You may see rowing teams on the water, and coaches on bikes sharing the straight path, because you’re passing Vienna’s rowing training center. There is also a restaurant and a public grill park beside the water. Nearby you can find the Vienna Watersports Arena and a cycling race course. Sports enthusiasts will certainly feel at home here.

Next you’ll cross a bridge over the New Danube and come to Roter Hiasl, a good place to refuel with typical Viennese food and drink. This ends the stage near Raffineriestrasse/Biberhaufenweg station of bus 92B, and the entrance to the national park.
