The biggest event of the year in Munich is the annual Oktoberfest, when the city dresses up in Lederhosen, consume vast portions of beer in tents and in beer halls, and perform traditional thigh slapping dances to the sound of Oompah music. The party starts in the last week in September, and runs for two weeks. If you want to visit Munich during the period of Oktoberfest, you should ensure that you book well in advance in order to ensure that you will have a hotel room to stagger back to, because the city gets very busy over the period.
