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.

This tough climb rose to fame during the 2012 Vuelta a España, when the final stretch to the summit was paved. It's almost 26 kilometers long, with a significant amount of elevation gain. The first six kilometers are easy, but from there, things get complicated: gradients of 5, 7, 9, and even 11% await you all the way to the Pajares pass. And this is where the fun begins: the ski resort's paved slopes with gradients reaching 25%. Of course, if the day is clear, the views will reward the effort.
