Walking tour of the city by William1982
The best thing to do in Vienna is just take a wander around the ringstrasse and take in the fantastic architecture and grandeur of Europe's true culture capital. You could also take in a few museums around the Museum Quarter, including the modern art gallery, which usually has 'an interesting collection' on show.
