Already pretty much at the end/beginning of the railway line, here it is even asphalted, before/later not anymore, but always easy to ride.

Near the town of Arenao, the greenway runs over this old railway bridge, today transformed into a wooden viaduct among the vegetation.

Along this section of the Montes de Hierro Greenway you pass through an environment where the area's mining past is most palpable. On the way there is the monument to the Mining People and there are some rest areas along the route.
