Dutch cycle paths are so well signposted, that even if you might not always know precisely where you are, you can hardly get lost. Just cycle on to the next signpost which will point you in the right direction. The distances given on the signposts are in kilometres.
There are around 50 numbered regional cycle networks in Holland, which are all connected. Together they form a large national cycle network that will take you all around the country. You can use the numbered cycle network to plan your own day trip.
