Munich is a large city, only slightly smaller than Berlin or Hamburg. The best way to explore is by walking and using the excellent public-transportation system. In the Altstadt, you can walk to all the attractions—in fact, you have to, because the Altstadt is a car-free zone.
By Public Transportation -- An extensive network of U-Bahn (subway), S-Bahn (light-rail), Strassenbahn (trams), and buses makes getting anywhere in the city relatively easy. You’ll probably use the underground U-Bahn and the aboveground Strassenbahn systems most frequently. The same ticket entitles you to ride U-Bahn, S-Bahn, trams, and buses. Purchase tickets from vending machines in U-Bahn and S-Bahn stations; the machines display instructions in English. You also can buy tickets in the tram or from a bus driver. Tickets must then be validated in the machines found on U-Bahn and S-Bahn platforms and in buses and trams; stick your ticket into the machine, which stamps it with the date and time. A validated ticket is valid for 2 hours. You can transfer as often as you like to any public transportation as long as you travel in the same direction.
Munich has four concentric fare zones. Most, if not all, of your sightseeing will take place in Zone 1, which includes the city center. A single ticket (Einzelfahrkarte) in Zone 1 costs 2.70€ if you pay cash and 2.60€ if you pay with a card. Short trips (up to 4 stops) cost 1.40€ if you pay cash and 1.30€ if you pay with a card.For more info visit the website of the public-transportation authority MVV.
