Vienna’s known for its extravagant architecture and you’ll fit all the main contenders in today. You’ll start with a panoramic bus tour past the Art Nouveau Urania observatory and the Danube Canal promenade, which is lined with bistros, bars and mini-manmade beaches. Then you’ll head out on foot for a photo stop at the Belvedere Museum – home to a pair of Baroque palaces and sloping gardens. After, the bus will drop you near the Hofburg, a former palace from the Habsburg era. From here, you can walk to St Stephen’s Cathedral for a closer look at its 137-metre-high spire and patterned roof. The bus will then whisk you to the Ringstrasse boulevard, where you can wrap up the tour with a stroll over to the Hundertwasser House. Designed by the Gaudi of Vienna, this brightly coloured building flaunts a forested roof and curved walls.
