Is the AS-261 a wide road through the Ponga canyon?
The AS-261 is a two-lane paved road, but the lanes are narrower than a standard highway. In the 16 km stretch between Puente de los Grazos and Cadenaba, the space feels tight because the rock face on one side and the river on the other leave very little shoulder room. While two cars can pass each other, you have to stay close to the white lines to avoid mirrors hitting the rock wall or the safety barrier.
What is the risk with the overhanging rocks in Ponga?
The main hazard on this road is the rock overhangs, known as "viseras". In many sections, the limestone wall curves directly over the asphalt. If you are driving a tall vehicle like a camper or a van, you cannot stay in the center of your lane; you have to move toward the middle of the road to avoid hitting the top of the vehicle against the stone. These overhangs also block the view of oncoming traffic on the many curves of the 16 km route.
Are there rockfalls on the road through Desfiladero del Ponga?
Landslides and loose stones on the asphalt are common, especially after a period of heavy rain or snow in the Asturian mountains. Small rocks can fall from the vertical cliffs and sit in the middle of the lane, which is a risk for tires and suspension. Since the canyon is deep and narrow, phone signal often drops out, so a breakdown inside the gorge means a long wait for help.
What should you check before driving the AS-261?
Check your vehicle's height before entering the canyon if you have a roof rack or a high cabin. Check your brakes, as the 16 km drive is a constant series of turns that require steady use of the pedal. In summer, local traffic and cyclists are frequent, and since the road is narrow, you need to keep your speed down to react to someone coming the other way around a blind corner.
