Pablo will pick up participants at Bilbao Airport in a 9-seater van and head west. During the journey, we will stop to visit the impressive coastal cliffs of the Asturian coast, where, if we have time, we can take a short walk to enjoy the views of the Cantabrian Sea and its rugged cliffs.

We will leave the ocean behind and head into the mountains, where we will make a short cultural stop in Cangas de Onís, Asturias, to see its famous medieval bridge before heading to the nearby Hotel Don Pelayo, where we will also have dinner.

In the morning, we will take the public bus that takes us up to the famous Covadonga Lakes in the western massif, where you can enjoy a pleasant circular walk to the Vega de Ario Refuge from the lakes, with impressive views of the central and eastern massifs.

After lunch, we will visit the jewels of the historical heritage of the Picos de Europa, the famous Cathedral of Covadonga and the cave of La Santina, the patron saint of Asturias, before driving to the rural cottage in Amieva for dinner and to organise the next hike, where Pablo drops the van and returns later by taxi, because from here we will have our own backpack for three days.

This historic route was the ancient road that connected the coast of Asturias with the interior of León for the exchange of goods, which even became a genuine Roman road. Today it is a beautiful trail that runs between the foothills of the Western Massif of the Picos de Europa and the Ponga Natural Park.

We will take advantage of the idyllic location of the Vegabaño mountain refuge to have dinner and sleep there, a magical place in dense forests inhabited by the elusive wildcat, the enigmatic Cantabrian brown bear, and the endemic Iberian wolf, among other beautiful wild animals.

We will leave the enchanted refuge behind and enter the dense beech forests to climb the nearby Pico Jario peak, which offers excellent views, from where we will descend to the Dobres hills and begin the descent through dense oak forests to Soto de Valdeón. We will follow the trail to the nearby Posada de Valdeón, where we will spend the night in the heart of the Picos de Europa de León at the Hotel Eigon. This is a very peaceful place with abundant wildlife and excellent views, as well as delicious blue cheeses.

We leave the wonderful Valdeón valley with the Western Massif behind us and skirting below the Cifuentes rocks, the Central Massif to our left, as we climb up through the Vacas sheepfold towards the historic El Mercadillo trail, which was formerly used by travelers from these valleys to reach the market in Liébana, where we are headed.

Along the way, we may be lucky enough to spot the endangered grey partridge, as this is one of the best places to see it, until we reach the Remoña pass with its impressive views, where we will eat a sandwich before continuing along Mount Quebres to Fuente Dé.

In Fuente Dé, where the Deva River rises from the top of its steep 800-meter cliffs, we will drive the van again to the Hotel El Oso in Cosgaya, where we will have dinner and spend the night.

After an excellent breakfast at the Hotel El Oso, we will travel by van to Fuente Dé, where we will take the cable car up to the balcony of the Central Massif of the National Park in the province of Cantabria. We will begin our hike along the gentle trail to the Covarrobres pass and, depending on the weather and the condition of the group, we will either take the much harder and more challenging trail to the Horcados Rojos pass or we will make the circular return via Áliva to the base of the cable car in Fuente Dé.

Depending on the conditions, it may even be possible to reach the summit of Torre de Horcados Rojos and walk down the circular route from Fuente Dé, but it will be up to the guide to decide which is the best option.

On this spectacular and popular route, we will experience the grandeur of the impressive limestone mountains of the iconic Picos de Europa up close and will almost certainly see interesting birds such as griffon vultures and short-toed eagles, and with a lot of luck, wallcreepers and bearded vultures. What we do hope to see are the agile Cantabrian chamois running around the hills.

We will return by van to the charming Hotel El Oso in Cosgaya, where we will enjoy a well-deserved rest and a delicious dinner.

As the final day of hiking, we will climb from Cosgaya to Doberganes, near the San Glorio pass, from where we will take the circular route of Pico Jano through large oak groves and livestock fields. The views of the three massifs of the Picos de Europa from the top of this conglomerate rock peak are breathtaking. Depending on the weather, we can also visit Collado de Llesba, where we can once again contemplate the peaks from the iconic sculpture of the Bear.

We will descend back to Potes, a historic village in the heart of Liébana in Cantabria, which we can visit and have time to buy some souvenirs before returning to the Hotel El Oso to spend the last night of this fantastic trip in the Picos de Europa.

Depending on the flight schedule, we can adjust our departure from Cosgaya through the La Hermida gorge and make a stop to visit the Cantabrian coast or, if there is enough time, even make a brief visit to the city of Bilbao before heading to the airport.

Visitors may choose to stay in Bilbao for additional nights to explore the city.
