The Puerto de Laza is a small and beautiful hill that joins the valleys of Roncal (starting from Isaba) and Salazar (starting from Ochagavía) in the Navarrese Pyrenees. Both sides are very similar: a very easy start on a winding road, in perfect condition but without a hard shoulder, passing through small towns and going up the course of the respective rivers Anduña (Salazar valley) and Urbi (Roncal valley); a final stretch of 2 - 3 kms that is harder without being too much so, although there are some slopes above 10%. The Salazar valley side becomes harder when leaving behind the detour to the Larrau port. From here to the port there are 3 km with an average gradient of 7%. On the other hand, the Roncal valley side becomes harder when overcoming a bridge over the river that has been with us since we left Isaba behind. From here it is barely 2 km with an average gradient of 7%. From a landscape perspective, it is a port that I love because you can enjoy the exuberance of the vegetation of the Pyrenees, crossing narrow valleys and only with panoramic views when you reach the top, where there is a viewing point that is worth looking out at. A port that I always recommend for enjoying cycle tourism. I leave you the profile of both sides produced by the website www.cyclingcols.com --> http://www.cyclingcols.com/col/Laza

The Col de Laza is located in Spain not far from the French border and the port of Larrau. Shorter than its neighbour, its ascent takes place in the middle of a beautiful forest which opens onto lovely views of the surrounding mountains.
