Things to do in Spain, no research required

The train line most Spain trips actually follow, bundled end to end. The capital brings the parks and the theater district. The coastal city brings the architecture everyone plans around and a Gothic quarter that will lose you at least once. The southern city closes it out with flamenco and an old town small enough to cover on foot. Bars and culture stops run deepest across the set, which says something about where this route’s strengths sit. Three cities, one import, no researching the next one from a train seat.
