With a length of 14.6 kilometers and a cumulative elevation gain of 1191 meters, this route is considered extremely difficult, making it an ideal challenge for experienced hikers. The journey begins at the Puente de los Fierros Station, a train station located in the municipality of Lena, in the Principality of Asturias. This starting point is not only a place of historical interest but also marks the beginning of a trek that delves into mountainous landscapes and deep valleys. As you progress, the route will take you through the Llanos, a municipality that spans 4.04 km² and borders several parishes, offering a glimpse into rural Asturian life. Along the way, hikers can enjoy the region's natural diversity, with panoramic views that unfold as altitude is gained. The local flora and fauna are a testament to the ecological richness of this area, where mountain peaks and green valleys intertwine in a captivating landscape. It is important to be prepared for the demands of this stage, as the combination of length and elevation can be exhausting. However, the reward of reaching the Puerto de Pajares, with its stunning natural surroundings, makes every step worth it. This route is not only a physical challenge but also an opportunity to connect with the history and nature of one of the most beautiful regions of Spain.
