A bay you can walk, and eat your way around.
San Sebastián is a coastal city that behaves like a small one. The bay is enclosed almost to a circle, the centre is flat, and the whole seafront can be walked end to end before lunch without it feeling like an outing.
Its food reputation is real, but it is easy to misread. The point is not the famous restaurants — it is the pintxo bar: one thing, one small drink, standing, then somewhere else. An evening is four bars, not one table, and nothing needs booking.
The Basque and Spanish names are used side by side here. The language, the eating culture and the year-round use of the beaches are what stop this feeling like a resort.
