Short pass but high percentage both uphill and downhill.

For me, this is one of the most difficult passes to climb, with astonishing gradients, exceeding 16% in some places. The view from the summit is magnificent, but be careful, the road is very narrow on the descent. An experience not to be missed for lovers of cycling and intense effort.

Although short, the ascent of Mount Artzamendi is classified as an hors catégorie due to its steep slopes. This is especially the case after kilometer 7, where the gradient often hovers around 15%, peaking at 20%.
