Beautiful place, always with a lot of people. Ideal when the surroundings are foggy.

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.

Besaide, an easily accessible place from Arrasate, Elorrio or Aramaiona, where the 3 Basque provinces meet, is a very emblematic place of Basque mountaineering, where on the third Sunday of September a commemorative act is celebrated in memory of all deceased mountaineers. We should have a little more awareness to preserve the clean environment.

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.
