In the Netherlands there are about 2 dozen long-distance bicycle routes, that are well-signposted. They are numbered LF1, LF2 etc.
The LF routes are known for their recreational character, with nice landscapes and pleasant bike paths.
The LF7 is one of the routes that go through Amsterdam. If you start it at the Buiksloterweg ferry, just behind the Central Station, in Northern direction, it will bring you to the Zaanse Schans.
From the ferry this is about 24 km.
The Zaanse Schans is an area with a number of historic windmills and other heritage buildings, one of the biggest attractions near Amsterdam.
Before the Zaanse Schans, the route takes you along windmill d'Admiraal in Amsterdam North, along a war plane monument, the rural North of Amsterdam, and through recreation area Het Twiske.
The total LF7 route is very long, the total route is between Alkmaar and Maastricht, about 300 km.
At Zaanse Schans you can follow the LF7 back to Amsterdam.
You'll note that LF7 in the one direction is called LF7a, in the other direction LF7b.
