  -                    Athens is not really the city to go around with a bicycle, as it does not have many bicycle lanes and the car drivers tend to drive quite aggressively.

                       Nevertheless (or maybe because of this) riding a bicycle in Athens has become lately some sort of a political (counter-)action, especially by young people with an alternative lifestyle.
  -                    In general, tourists not familiar with the Athenian traffic are not advised to use a bicycle as a principal means of transport.

                       Small rides are safe though in the long network of pedestrian streets around the Historical Centre of the city and can be quite enjoyable indeed.

                      Pleasant walking can also be had in Plaka, especially its upper reaches, and in much of Kolonaki, and the National Garden can provide a welcome respite from the heat and noise of the city center.

                      On the other hand, Athens' traffic can make crossing the street in many areas a hair-raising proposition, and even walking down many major streets can be an unpleasant experience of noise and pollution.
                      Cars and motorbikes parked blocking the sidewalks (illegal but ubiquitous) can also make a stroll difficult.
                      Fortunately, much of the traffic-plagued area of the city can be avoided by judicious use of the new Metro, which goes most places a visitor would want to see or to walk around in.
