If it's your first time in Vienna, a morning bike tour is a great idea since it will let you see all the major attractions and landmarks in just a few hours.
You will pass through Ringstrasse, visit the oldest amusement park at Vienna Prater, Stadtpark with the Johann Strauss Monument, and the Danube. You will explore the city centre—the Vienna State Opera, Stephansdom, Heldenplatz, Hofburg, Parliament Building, City Hall, Burgtheater, Schottenkirche, and much more.
You can opt for a nostalgic bike or mountain bike and continue your tour on the outskirts of the city at numerous vineyards. Guided bike tours usually run between April and October.
