EurAide helps the German Railroad explain the Bayern Ticket in the English language so that non-German speakers can use it, too! It is sold at the EurAide office in the Munich train station and any counter of the German Railroad in Bavaria.
One ticket (EUR 29 for up to five people or EUR 21 for one person) allows travel on ALL regional trains (see below) in Bavaria for one day after 9 a.m..
On weekends and German federal holidays, the 9 a.m. starting rule is dropped and the ticket works all day. Note: the ticket is always valid until 3 a.m. the following day (i.e., 3 hours after the day of validity ends).
Regional trains are defined as RE (Regional Express), RB (Regional Bahn), IRE (InterRegioExpress) and S-Bahn (suburban metropolitan) trains.
Bonus Nr 1 - the ticket covers travel on regional trains from Bavaria to Salzburg (and return) because this city is considered the "border station" between Germany and Austria.
Bonus Nr 2 - the ticket covers travel on regional trains from Bavaria to Ulm (e.g., coming from Augsburg), even though Ulm is in the neighboring province of Baden-Wuerttemburg.
Bonus Nr 3 - the ticket covers the ENTIRE public transportation system of Munich (even those segments not operated by the German Railroad).
Example for using the "Bayern Ticket" on weekdays to reach Fuessen (town near Castle Neuschwanstein): The RE train from Munich at 10:51 a.m. (leaves after 9 a.m. and) requires no additional ticketing for the two-hour train ride. After you arrive in Fuessen at 12:57 p.m., take the local bus (NEW: this bus is now covered by the "Bayern Ticket") that leaves from the front of the train station at bus platform number 2.
Example for using the "Bayern Ticket" on weekends to reach Fuessen (town near Castle Neuschwanstein): The RE trains from Munich at 08:51 a.m. (no 9 a.m. rule) and 10:51 require no additional ticketing for the two-hour train ride. See the previous paragraph for information about the bus connection between Fuessen and the castle.
