Nice route to enjoy the views and paths

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.

Next to the Mirandaola park is the old forge of the same name, which has currently been converted into an ethnographic museum. You can book your visit through this link: https://lenbur.com/es/museos/ferreria-de-mirandaola/.

Dominating the Léniz valley, the hermitage of Aitzorrotz is one of the places that you will most like to enjoy a sunrise. From the neighborhood of Bolibar in Eskoriatza, and along a rural road, you can easily reach the hermitage.
