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.

This 192-meter-high peak lies at the westernmost end of the Munarrikolanda Mountains. This mountain range is an important megalithic site stretching between the Saierri and Munarrikolanda mountains and contains a total of seven monuments (burial mounds and dolmens).

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...

A beautiful beach with high waves depending on the weather, also great for surfers (there's also a surf school)! There's a small swimming area with lifeguards on duty.

Cool castle, graceful as it stands there. By the way, a really beautiful hiking area.

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.
