During the mining era, this pass served as a discreet link between mines on either side, and minimal traces of old cart and mule traffic remain, though they don't coincide with the current road. From above, the wind is almost constant, and the view towards the Saliencia lakes has that air of a "natural viewpoint" before the term even existed. It's perfect to mark on Komoot as a key point on your route due to its spaciousness, its somewhat hidden history, and its character as a natural border.

Upon reaching the summit, you don't arrive at a village or a tourist center, but rather at a kind of natural balcony overlooking the Lena mountain passes, which gives a strange feeling, as if you've stepped onto an empty stage. And on clear days, the wind is louder among the mountain passes than any car, because traffic is minimal.

For decades, La Cubilla was practically a ghost town: a road built to connect mining valleys, used more by livestock farmers and scattered trucks than by travelers. This lack of traffic left a remarkably clean route, free of curves, absurd straights, and modern widenings: pure mountain design from another era. That's why many cyclists say it "looks more like an Alpine pass than a Cantabrian one," with those giant limestone walls silently accompanying you.

Among the theories surrounding the unusual name of this mountain pass, one is the popular legend that some shepherdesses were caught in a blizzard and died in a nearby shelter. In any case, the pass is located in a stunning setting.

One of the great Asturian mountain passes, without a doubt. Generally unknown to the general public, it's rarely used in professional races. It has two clearly distinct slopes. The southern slope, which begins in Pola de Allande, is gentle and steady, along a road in good condition. It shares much of its climb with Puerto del Palo, which it turns off from just 3 km from the summit of Puerto de la Marta. The northern slope, which comes from Villayon, is uneven, with very tough sections and several rest stops and descents. It reminds me a lot of the Croix-de-Fer from Sant Jean de Maurienne, not because of the landscape, but because of the type of pass.

It's one of the major mountain passes in southwestern Asturias. It connects Pola de Allande with Berducedo. It's part of the northern variant of the Camino de Santiago. Highly recommended for its views, whether climbing its two slopes or from its summit.
