This hexagonal-shaped hermitage from the 18th century was built because the previous one was in ruins. The three large rocks inside draw attention, holding each other together. Within these rocks is the figure of the Archangel Saint Michael.

This 386 meter high summit is located in the Arno massif, above the town of Ondarroa. This is a good point from which to observe the Cantabrian Sea and some of the peaks that surround you.

Next to the GR123 is this small, but beautiful hermitage, surrounded by green mountains and right on the dividing line between Bizkaia and Gipuzkoa.

Also known as Puente de Calatrava, because it was built by the famous architect and engineer Santiago Calatrava. It is built right at the mouth of the Artibai River, when it pours its waters into the Cantabrian Sea. It is 70 meters long.
