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.

Located in the Duranguesado region, the town of Ermua is known for its rich history and its beautiful natural landscape. Here you can enjoy the local gastronomy. The town's name may come from the Basque term Emuas, which means border area or terrain, due to its location on the dividing line between the provinces of Vizcaya and Guipúzcoa.
