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.
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.
