When you arrive at Munich’s international airport the first thing you want to do is of course head into town and find your hotel. The airport itself is located far north of the city. Your choices are then to take a taxi, a bus, rent a car, or take the train into town.
By Train: Most locals and tourists alike take the train as it is usually both the fastest and cheapest option. The trip takes about 45 minutes to the city center where the majority of tourist hotels are located. Both the S1 and S8 trains run every 20 minutes almost around the clock (they are less frequent between 1am and 5am) so you should never have to wait more than 10 minutes for a train into town from the Munich airport.
If traveling alone, the cheapest ticket is to the city center is called a 4 zone Einzelfahrkarte and costs €10. However, for only 80 cents more you can get an all day ticket for the entire system, (good until 6am the next morning) which is called a Single-Tageskarte Gesamtnetz and costs €10.80.
If you are traveling with two to five people, there is what is called a partner ticket, which is the cheapest option for groups by far. For a group ticket for up to five people which covers the entire system until 6am the following day, it costs €19.60.
Before you board the train make sure to stamp your ticket (so that it has a date and time). You only need to stamp it once.
By Taxi: Taxi is the most expensive option, although not necessarily the fastest. Taxis in the Munich area are usually Mercedes or BMWs, so you will be riding in luxury, but the trip downtown will easily cost €60 on average.
By Bus: There is a direct bus that you can take from the airport to the city center for €10.50 or €17 round trip per person. The bus usually takes approximately 45 minutes, but it depends on traffic so can take longer depending on the time of day. Buses run every 20 minutes from just outside the airport.
Car Rental: You can always rent a car to get around town, but this is inconvenient for a lot of sightseeing around Munich itself and is probably the most expensive option.
