Potsdam

Potsdam is the capital city of the German federal state of Brandenburg and is part of the Metropolitan area of Berlin/Brandenburg. It is situated on the River Havel, 24 km southwest of Berlin city center.

The tram and bus system in Potsdam is very modern and overall excellent though confusing. Potsdam is, together with Berlin and parts of Brandenburg, part of the VBB transportation network. That enables you to change trams and buses pretty much at will, as long as your ticket is valid for the zone you're in. The inner city of Potsdam is in Zone A, the outer parts are in Zone B, and the hinterland is Zone C. Be aware though, as Potsdam itself lies in Berlin's Zone C - Berlin's outer parts are Berlin Zone B and so on. Tickets can be bought at ticket machines in every tram and bus. Unfortunately they're of no big help when it comes to choosing the right ticket, and furthermore they only accept coins and rechargeable "Geldkarten", but no bills. It's best to get detailed information about prices and zones at Potsdam's central station.
