This is a high difficulty enduro circular route that takes us from Pola de Gordón, crossing Barrios de Gordón, to Collada de Urdiales. From there we will skirt the south face of Pico Miezca towards Collado de las Yeguas from where we will link up with the ridge of Pico Fontañán from where, a few metres before this peak, the vertiginous descent begins. Those who wish can turn off to the southeast before the descent and visit the civil war bunker on the summit of Fontañán peak. This is an exposed route with sections of very high difficulty, only recommended for experienced riders. Care should be taken in snowy or wet conditions, as some of the upper sections may be unrideable.
