The map above shows all the bike paths in the Netherlands as of April 2018. The total length of the the cycle network is over 35,000 km long, although this map only shows dedicated/independent cycle paths, not roads that only have a cycle lane.
The Netherlands (aka Holland) is the 30th most densely populated country or territory in the world and the densest country in Europe with a over 10 million people. So it’s understandable that the Dutch might think that their country is a little bit crowded.
However, the map above flips this idea on its head.
