Don’t come by car! Just don’t.
This is how you can get there by public transport:
Taking the U-Bahn to Theresienwiese
The lines U4 (green) and U5 (yellow) take you from, for example, Odeonsplatz, Karlsplatz/Stachus, or Hauptbahnhof directly to Theresienwiese in a few minutes. For those for whom Theresienwiese station is too busy, you can travel one stop further to Schwanthalerhöhe.
The U3 (orange) and U6 (blue) go from Odeonsplatz, Marienplatz or Sendlinger Tor, arriving in approx. 5 minutes at Goetheplatz or, one station further, Poccistraße. From here it is just a few minutes walk to the east and south entrances to Oktoberfest.
Taking the S-Bahn to the Wiesn
The main S-Bahn lines (S1 to S8) all go to Hackerbrücke: for example, it’s 2 minutes from Hauptbahnhof, 5 minutes from Marienplatz, and 10 minutes if you get on at Ostbahnhof. From Hackerbrücke station you can comfortably walk to the main entrance of Oktoberfest in 10 minutes. You can’t get lost, simply follow the people in Dirndls and Lederhosen!
