Cangas de Onís Travel Guide: An Asturian Stone Bridge Over Blue-Green Water

Cangas de Onís

A quiet riverside town in the Asturian foothills, built around its famous ivy-clad Roman stone arch bridge over a clear green river.

Cangas de Onís is known throughout Spain for one striking scene: its ancient, multi-arched Roman stone bridge, its stonework softened by centuries of ivy, spanning a river running clear green-blue over a bed of smooth, rounded stones. A hillside settlement is visible in the distance, and dense trees and rocky terrain crowd the banks on both sides.

The Sella river winding through the Picos de Europa foothills

It's a small town rather than a major city — the bridge, the river, and a scattering of old stone buildings nearby are the main draw. It's the kind of place worth a stop for the light on the water and the texture of the old stonework, on the way between the coast and the mountains.

Where to take photos

• The old stone arch bridge — an ivy-covered, multi-arched crossing over the river, the clear centerpiece of the spot.
• The riverbed below — smooth, multicolored stones under vivid blue-green water, with distant mountains as a backdrop.
• Village stonework — old stone facades and tiled roofs typical of rural Asturian architecture.

When to go: Midday in late spring through summer, when the sun is high enough to light the riverbed and turn the water a vivid blue-green.

Where to stay: A good overnight base for the Picos de Europa — otherwise pair it with a night in Gijón and push on toward the mountains.

What to eat: Try fabada asturiana or a bottle of local sidra — both are Asturian staples you will find right in town.

Tip: Shoot the bridge from river level to get the ivy-covered arches reflected in the still water, rather than from the road above.
