Berlin is a sprawling city, so you better study up on the transportation system! (Hint: The U-Bahn is your new best friend.)

Walking

Berlin is roughly eight times the size of Paris, so walking to and from popular tourist destinations especially those spread out over the former East and West Berlin is not always the easiest feat.

U-Bahn, S-Bahn and Bus

The system is efficient and extensive. The U-Bahn (think of the "u" in urban) travels within the city while the S-Bahn travels to the suburbs. Buses cover many of the gaps on the eastside that aren't covered by the U-Bahn. Buses run at night after the U-Bahn stops operating.
