Meeting up with the leader and transfer to Poncebos. We begin this incredible trail running trip with a hard stage, as we have a elevation gain of 1,500m in just 6 km. We start in Poncebos towards Caín, 8 km practically flat to stretch our legs along the famous Cares Gorge until we reach “Culiembro”, where we leave the route to take the “GR Reconquista” and climb the “Canal de Culimebro”, 1,000m ascending in just 4 km. Once in Vega Maor where the Canal ends, we continue along the Moandi pass and then the path well-marked to the Vega de Ario Refuge. We rest with wonderful views. Dinner and accommodation in Vega de Ario Hut.

Breakfast. After breakfast, the route is straightforward, practically all of it downhill and along a well-marked path until Lakes Ercina & Enol. From Lake Enol until Vegarredonda Refuge is about two hours walking up, and just before you reach the refuge, many of the higher peaks of the western massif become visible. Dinner and accommodation in Vegarredonda Hut.

Breakfast. Now, we go up until we reach Collado Les Merines (2.100 m). The green colour under our feet turns into the grey rock in an enormous limestone world through the Pozas Jou (karstic pothole). We will rest to drink some cool water from the Prieta spring. From one “jou” to another, we will cross stony ground before we reach the enormous Vega Huerta. We will continue along the marked path that takes us southwards down the Canal del Perro to the Frade shelter. From there, we have to make the easy descent among the beech trees surrounding the Vegabaño shelter, where we will encounter some indescribable beauty spots, such as the source of the Dobra River and the thousand-year-old oak tree of Vegabaño. Dinner and overnight stay at the refuge.

Breakfast. We leave the Vegabaño shelter behind us, enter the beech grove, and go up a gentle slope; we will pass the home of the capercaillie. Continuing through the virgin woodland, we will go up the Dobres rock and start our descent into the Valdeon valley, among brooks, until the path gets wider and becomes a track that will take us to the village of Caldevilla. Having reached this point, we will follow the course of the Cares River to the town of Posada de valdeon, where we will have lunch and can buy food in the supermarket. After lunch, we go on until Santa Marina de Valdeon. Dinner and overnight stay at the refuge La Ardilla Real

Breakfast. Transfer to Pandetrave mountain pass and then by track to Valcabao. Today we start with a beautiful walk from Valcabao to Collado Jermoso Refuge by the Canal de Pedabejo, walking near the spectacular Vega de Liordes and along the cliffs of Colladinas until arriving at Collado Jermoso Refuge, our first stop and overnight. We rest and look forward to watching the fabulous sunset with beautiful views of the Valdeón valley and the Western Massif. Dinner and overnight at the refuge.

We leave the Refuge to the Collada Ancha and Tiro Casares to reach the Cabaña Verónica Refuge. From here, we descend to Horcados Rojos with incredible views of Naranjo de Bulnes and drop to the Jou de Los Boches by a steep and exposed slope unsuitable for people with vertigo. We cross the moonscape of the Jou of Los Boches and Jou sin Tierre until arriving at the Urriellu Refuge. Dinner and overnight stay at the Refuge

Breakfast. We leave the Refuge leaving behind us the west face of the emblematic Picu Urriellu. We quickly headed towards Jou Lluengo, a typical Picos de Europa scree section, until we reached the famous Camburero Canal, a very steep descent to the Valcosín Canal. An area that is flatter and with more vegetation to reach the town of Bulnes. After a rest and lunch in the town, one last descent through the Canal del Tejo to Poncebos, where the vehicle awaits us to return to Arenas de Cabrales or Cangas de Onís. End of services.
