So you’re visiting Vienna and you’re looking to book a bike tour. Good idea! Vienna is a sprawling city with numerous attractions and some of them are found outside the Innere Stadt or District 1, so a bike tour is a great way to cover a lot of ground. While major landmarks like Hofburg Palace, St. Stephen’s Cathedral, Vienna State Opera, Albertina and Volksgarten are clustered fairly close and easy to reach on foot, other places require a bit more effort to get there.
