Most cities in Germany are known for their excellent infrastructure with pedestrian zones and numerous bike paths. Especially in the last decade, many cycle paths were networked across Germany. Therefore, it is worthwhile to explore many attractions by bike. For example, a trip on the Spreeradweg with Berlin as a starting point is a lasting experience.
But watch out! Especially in Berlin you should not get in the way of a cyclist. Running on a bike path is not only dangerous but also annoying. So it can happen that the actual users loudly announce their anger about the disturbing pedestrian.
But do not worry, you can not accidentally get on a bike path, because most of them are clearly marked by bollards, boulevards or other obstacles.
