From Astillero it is worth getting to Santander passing through different discontinuous bike paths that almost connect to each other.

This climb is a beast, but worth it. First part is tough, but fine and offers nice views. Then you get some relief for a few hundred meters and see a warning sign with “18%”. This leads to a few hairpin turns that leave you thinking “this is doable”, but then the real deal starts. Long stretches of 15% and up without any recovery. It will test your willpower, but you feel accomplished when reaching the top and the view can’t be beat.

German-made locomotive that entered service in 1913 to transport iron ores and limestone from the Camargo mines to its factory. It is located on the greenway, near the train station, converted into an exhibition hall and tourist information office.
