This cycling route in the shape of the number 6 will connect 6 mailboxes in the Netherlands, Belgium and Germany. The route will be defined by letters that are sent between mailboxes and delivered by Jordi Möllering.

​

Nearby each you will find a sign with instructions for the route and information about the project. Inside the mailbox you will find a paper map. ​On this page you can also find the route in an image and as a gpx track. We expect the route to be online in October 2025.
