Location of the Picos de Europa and Casa Gustavo Guesthouse

A Little Geology

The Picos de Europa are a small but impressive range of karstic limestone mountains in the north of Spain just 20 kms from the Costa Cantábrica. Straddling three provinces - Cantabria, Asturias and León, they are split into three massifs - Western (El Cornión), Central (Los Urrielles) and Eastern (Andara), by the rivers Cares and Duje. Bordered by, in the east and south the valleys of Liébana and the river Deva, and in the west the river Sella, the Picos de Europa enjoy a temperate climate with the mountains on the Asturian side bearing the brunt of the prevailing, westerly weather fronts. The valleys of Liébana, lying on their eastern flank, find themselves in a natural rainshadow and enjoy a much drier climate than the coast.

The topography of the Picos makes them notoriously complicated to navigate, the karstification process having compounded the effects of glaciation by creating deep hollows (hoyos) and vertical mountain walls. (Espeologists can explore some of the deepest caves in Europe). Water is scarce in the high Picos with only occasional, small springs. Among the highest peaks are Torre de Cerredo (2,648m), Torre de Llambrión (2,642m), Peña Vieja (2,613m) and Peña Santa de Castilla (2,596m), although the most well-known is El Naranjo de Bulnes (2,519m), aka Picu Urriello in the local dialect. This lump of a mountain sticks up like a thumb from the central massif and, along with the rest of the range, can be seen, on a clear day, from the coast. According to legend, the Picos de Europa were so named by northern European sailors approaching the Costa Verde from the Bay of Biscay.

A Little History

cares gorge


One of the most popular walks for visitors is the path along the Cares gorge or Garganta del Cares. Not for the vertigo-prone, this track was carved out of the western face of the gorge during the 1920s while making an 11km feeding canal for the hydro-electricity station in Poncebos - an amazing feat of engineering for those times.

Covadonga, in the western massif, was the site of a battle (or a skirmish depending on points of view) in the year 722 in which an army led by Don Pelayo defeated a Moorish invasion attempt. Using their knowledge of the precipitous terrain, the Asturians led the Arabs into the mountains and then ambushed them, making for the first defeat of the Arabs and leading to the Christian Reconquest of Spain. The surviving Arabs fled over the Picos via the lakes above Covadonga, now another popular tourist attraction, only to be engulfed in a landslide at Cosgaya in the Camaleño valley on the other side. Don Pelayo was declared the first king of Asturias and Cangas de Onis its' first capital.



The grotto near the Basílica de Covadonga houses Don Pelayos' tomb along with the Virgen, or Santina, of Covadonga and is the second most important Catholic site in Spain.

Around the same time, a monastery was founded in Liébana. Originally named the monastery of San Martín of Turieno and Benedictine in order, it later evolved into Santo Toríbio and became Franciscan. The gothic church that now stands on the site, 2km from Potes, dates back to 1256 and is home to the Lignum Crucis, reputedly a piece of the holy cross on which Christ was crucified.


The works of an 8th century monk, Beato de Liébana, are also kept here including some colourful works of art displayed in a permanent exhibition in the church cloisters.

The monastery now standing next to the churchla viorna was built in the 17th century and restored in 1961. A huge, concrete cross on the hill of La Viorna above dominates the view over Potes. Santo Toríbio is the third most important Catholic site in Spain. Both holy sites are obligitory stopping points on the pilgrimage to the most important, Santiago de Compostela - journeys' end.


Where We Are

Five minutes drive or forty five minutes walk from the ancient, market town of Potes, thirty torre infantado potesminutes from the cable-car at Fuente De and forty five minutes from the coast, Casa Gustavo makes an ideal base for a holiday in Cantabria.
