At 684 meters high, this is the highest peak of the massif that bears its name. It is located on the left bank of the estuary. During the Civil War, the so-called Battle of Sollube took place on its slopes for eight days.

A small chapel that marks the peak of Bizkargi at 557 meters. Beautiful views on a clear day.

This bridge is an incredible find in the middle of the forest. It is covered with ivy and in summer it is so green that it is hardly visible. If you go down next to the river you can take some great photos with the water and the bridge. For many years this bridge has had to survive numerous floods. It's amazing that he's still here.

Bermeo is a beautiful seaside town and worth a visit, but if you can't go, the view from the trail is pretty good too.

At the top of Mount Arrola, a fortress was built 2,300 years ago that gave shelter to the population of the area. An oppidum that reveals to us the way of life of the 2nd Iron Age, with monumental walls, gates and moats. It is one of the most important fortified towns in the Eastern Cantabrian Sea.

The Artzubi Romanesque bridge was built in the 16th century. Wherever you see it, it has overcome floods and floods from the Golako River, which passes below and flows into the Oka River. In another time there were more bridges like this one, but it is the only one in the area that has endured. https://www.urdailife.com/artzubi-puente-cuento-arratzu-mendata/
