If you climb from Araotz, follow the PR, and the climb is very easy and short. From the cave parking lot, it's much steeper and zigzags. About 2.5 or 3 km with a lot of elevation gain.

Achievement of several waterfalls hidden among a beech forest. Although they show their maximum splendor after a rainy episode, the path turns into a muddy area which makes it quite uncomfortable to run.
