Spain is Europe's second-largest country by area and one of its most visited, yet vast stretches of its interior remain almost unknown to international travellers. The coastal clichés — sun, sangria, sangria — are real enough but they're a fraction of the picture. This is also the country of Velázquez and Picasso, of a culinary tradition that has produced some of the world's finest restaurants, of a linguistic landscape that includes Basque (unrelated to any other living language), Catalan, Galician, and Castilian Spanish spoken across 17 autonomous communities that each function like a distinct culture.

The geography alone is extraordinary: the high central plateau ringed by mountain ranges, the green Atlantic coast of Galicia, the volcanic Canary Islands, the lunar landscapes of Almería. Travel slowly enough and Spain can occupy a year without repeating itself.
