A quiet riverside town in the Asturian foothills, built around its famous ivy-clad Roman stone arch bridge over a clear green river.
Midday in late spring through summer, when the sun is high enough to light the riverbed and turn the water a vivid blue-green.
Try fabada asturiana, a hearty bean-and-chorizo stew, with a pour of local sidra poured from a bottle held high overhead to aerate it — the traditional escanciado technique used at any sidrería in town.
A good overnight base for the Picos de Europa — otherwise pair it with a night in Gijón and push on toward the mountains.
Shoot the bridge from river level to get the ivy-covered arches reflected in the still water, rather than from the road above.
