Although we were caught in the fog and could not enjoy the views, the route is beautiful, worthy of the effort it requires, which is not exaggerated either.

The Mirandaola park is a haven of the history of Basque iron. It is home to the old traditional forge where you can see how iron was worked in the 19th century. In addition, there are various buildings and structures where iron is the protagonist.
