The public transport system in Munich that is operated by the MVG is really good and quite reliable. It is possible to choose between U-Bahn (underground), S-Bahn, buses and trams. The transport system of Munich is very developed and fairly easy to use. The service hours usually are from about 5.00 a.m. to 1.00 a.m. On the weekends and on official holidays, the service hours are extended. In addition, there are night buses and trams that run about every hour during the whole night.
It is recommendable, however, to get a map of the network from one of the information centers. If this is not possible, there are maps at each station as well, mostly near the ticket machines.
