For being a major city surrounded by acres of developing suburbs,
Madrid is a easy city for the tourist to navigate, because the center is rather
compact. The sidewalks in the central areas are wide and very walkable, the metro is
one of the largest in the world and is currently being extensively modernized,
buses run extensively throughout the city as well as to the suburbs and a taxi
is only a hand gesture away.
The public transportation system is safe, reliable, extremely affordable and
used by everyone - young, old, rich and poor alike..
If you're planning to spend an extended period of time, monthly passes (abonos)
are valid for the metro, train and bus. If you have an InterRail or Eurail pass, RENFE
allows you to use their urban and suburban trains (cercanías) free, which is a
terrific value for trips out of town.
