Why go to Spain
Spain receives around 90 million international visitors a year, second only to France, and an extraordinary share of them go to two coastlines and never see the country behind them. That is a genuine loss, because Spain is less a single nation than a federation of regions that spent most of their history as separate kingdoms and still behave that way.
The differences are not decorative. Galicia in the northwest is green, wet, Atlantic and Celtic-influenced, with bagpipes and octopus. Andalusia in the south is dry, hot and shaped by eight centuries of Islamic rule that left the Alhambra and the Mezquita behind. The Basque Country has its own language, unrelated to any other in Europe, and arguably the best food on the continent. Catalonia has its own language too, and a capital that looks nothing like Madrid.
This guide covers ten destinations chosen to show that range: three great Andalusian cities, two very different capitals, an Atlantic food city, a Mediterranean one, an island, a volcano and the end of a thousand-year-old pilgrimage. The high-speed rail network makes most of them two or three hours apart, which is what makes a trip across several of them realistic.
