Alto de L'Angliru, Mountain pass in Asturias, Spain.
Alto de L'Angliru is a mountain pass in Asturias that climbs approximately 13 kilometers through green mountain slopes to reach an elevation of 1570 meters. The road features consistently steep sections, with some portions exceeding 23 percent gradient, making it a physically demanding route.
A traditional cattle track was paved into a road in 1999, soon drawing the attention of professional cyclists from across Europe. Since then, it has become a regular stage in the Vuelta a España race and stands as one of the sport's toughest challenges.
Professional cyclists consider the Angliru as a defining challenge in European cycling, with many regarding it as a test of physical and mental strength.
Visitors should come prepared with sturdy footwear and weather-appropriate clothing, as the elevation and exposed location can bring quick weather changes. The best time to visit is on dry days when the road is safe for cycling or walking.
The Cueña les Cabres section in the final stretch contains some of the steepest gradients on the entire route and challenges even experienced riders. This last trial is known for pushing athletes to their physical and mental limits.
