生物圏保護区デバビアの峠・トップ4

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.

The La Cubilla mountain pass is located at an altitude of 1,683 meters, on the border between Asturias and León. Its rugged terrain and the beauty of its surroundings have earned it the title of stage finisher of the Vuelta a España, making it one of the most iconic climbs among cyclists.
