Munich's city centre is a pedestrian zone, so many of its attractions can be reached on foot, which is also the most pleasant way to explore certain parts of the city. The efficient and integrated public transport system is excellent for getting around beyond the centre. It consists of buses, trams, the U-bahn (subway) and the S-bahn (suburban train) that operate from about 5am to 1am, with hourly buses and trams servicing main routes throughout the night. Tickets must be validated on entering stations or on boarding, are transferable between all forms of transport, and valid for two hours after being stamped as long as one travels in the same direction. Fares are zone based and the system is well-organised and easy to understand.
There are various day passes available as well as the Munich CityTourCard, which covers all transport within the city and includes discounts to the main attractions. Taxis are safe and convenient, but expensive. You can hire a car easily but it is often better to use public transport in the big European cities to avoid frustration and confusion. You can also hire bicycles at very little cost and this is a lovely way to get around.
