After Prater, I took the U1 to Donau city—Vienna DC. This city, on the river Danube, is where many of the offices and newer residential areas have come up. This is the place where all the modern buildings are. In other words, nothing much to see here. But this is where you need to get off to visit the Danube Tower. To get there, get off the station and walk across all the buildings you see. You’ll see the Danube tower in the middle of a huge park.
It’s 165 m high. Entrance is 5.3â¬. The lift takes about 30 seconds to get you on top. And... there’s a café and restaurant on top. Yeah. I had coffee and Topfenpalatschinken (pancakes filled with sweet cream cheese, served with custard cream and chocolate). The restaurant rotates (it takes 26 minutes for a complete rotation), which means you can sit at one place and get a 360°-view of Vienna.
One can also bungee jump from the tower (probably the only place in Vienna?).
