Departure from Fuente Dé escalating on one of the most spectacular walking paths created during the mining era, the tornos de Liordes, after the ascension of one of the peaks in the area, we will continue walking along the Vega de Liordes to later reach Las Colladinas and arrive at the refuge of Collado Jermoso situated in an breathtaking enclave. Situated in the Leon face it counts on breathtaking sites of the occidental mass of the Peaks, where one can see Peña Santa de Castilla at the summit.

We will depart from Collado Jermoso and head in the direction of Cabaña Verónica through Horcada Casares. Once this point is reached, we will begin our decent of the Boches, a technical decent with the aid of a cable. Once this part has been reached we will continue through the Hou without soil to reach the Refuge of Urriellu located at the base of Pico Urriellu, whose Summit is the best representation of the European Peaks.

We will depart from Urriellu, to ascend steadily Horcada Arenera. Once we arrive at Cabrones we will find a completely different environment from Urriellu, with less visitors due to its distance from the center of town. From here the only direction is down towards civilization through the Tejo Canal, ancient and only way of communication between Poncebos and Bulnes until the construction in the year 2000 of the cable car. After crossing the River Cares on the Jaya bridge, we arrive at Poncebos where we will finish our trek.
