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.

This walk is beautiful but we did it in April and it was very wet and slippery. There was a part with lots of stones and mud and leaves where you sank half a meter. Not very steep until the sanctuary. There we had to zigzag very steeply up the rock. Better to walk up than down but that part is strenuous and not average.
