The Karabieta pass, located at a height of 565 meters, is one of the most recognized climbs in the area. The climb is not too long and its slope is quite progressive. A slightly demanding climb, but with wonderful landscapes.

Coming from Hernio, it seems to me the best place to pay a little tribute. It reminds me of the inn in the fields of Urbía.
