In reality it is not a stretch of the Vasco-Navarro railway track but it was the path that passengers from Antzuola used to get to Bergara or to get the train.

Unlike other parts of the Vasco-Navarro green route, this stretch does not go alongside the road but crosses mounts and forests and offers spectacular views.

After going through several tunnels, you come to Bergara, the hamlet Bolu and for a time you can see the green and white marks of the SL-Gi route.

Go through Bergara and in the hamlet Mekolalde the route joins up with the Vasco-Navarro.
