The summit is 250 meters high and can be reached via a singletrack trail from the forest road. It's best to climb from the Bilbao side and then descend the singletrack towards Basauri. Coming from Basauri, it's not really rideable; pushing would be necessary.

Definitely a highlight, but unfortunately, the castle was covered in scaffolding when I visited. The castle dates back to the Middle Ages but was later almost completely rebuilt.

Definitely a highlight here. Shortly before the summit, a narrow single trail leads from the forest road to the summit, which is easy to miss...

This medieval castle is one of the most beautiful in Biscay. It is located in a beautiful setting, on a hill and on top of some rocks, and is surrounded by a century-old forest.

The summit of Unbe (302 meters) is the highest in the massif of the same name. When you reach its highest part you will discover its curious mailbox: a nice blue "beggar" who carries his backpack.

The top of Mount Munarrikolanda (257 meters) is the highest in the Munarrikolanda mountain range. It hides a bunker from the Bilbao Iron Belt. That belt is a defense system that was built in the civil war to defend the city against enemy attacks.
