But keep in mind that all those that go to the south go up, logically, on the north faces, come on, they are usually full of mud ... better for when the weather is good.

The Alto de Azpirotz is a mountain pass that is better known for its geographical position than for the hardness or percentages of the ascent. Basically since it is on the border of the province of Guipúzcoa, where it is on the edge of the Valle de Larraun.
