You might think that Oktoberfest celebrations would begin in October. You are being too literal. In Munich, where Oktoberfest originated more than two centuries ago, the festival begins in mid-September and runs to the first Sunday in October. That wasn’t always the case. The original party celebrated the marriage of Prince Ludwig of Bavaria to Princess Therese of Saxony-Holdburghausen on Oct. 12, 1810. Copious beer-drinking wasn’t added for some years. Oktoberfest is still held on the same spot — Theresienwiese, or Therese’s Meadow — but has grown in duration (usually 16 days in Munich) and number (all over the world). Now, to commemorate Oktoberfest, CheapFlights.com has compiled its 10 favorite beer gardens — three in Munich, two in the U.S. (Milwaukee and Brooklyn), and the rest in Brazil, Tokyo, Austria, Sydney, and Vancouver.
