The castle is gigantic and beautiful to look at, unfortunately it has been surrounded by a construction fence for ages. Unfortunately, you can't see much. Whether the detour is worth it, everyone has to decide for themselves.

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 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.
