The journey begins with the lush, green hills of the Basque Country, where the Atlantic winds create dramatic cloud formations over the Bay of Biscay. As you drive southwest, the landscape shifts to the vast, golden wheatfields of Castile and León, punctuated by medieval hilltop villages. Crossing into Portugal, the terrain becomes more rugged, with the Serra da Estrela mountains offering breathtaking views before descending to the Atlantic coast.

Local commerce varies significantly: in the Basque region, you'll find artisanal cheese (Idiazabal) and cider houses (sagardotegiak). In Castile, explore markets for chorizo and morcilla. Portugal offers its famous pastéis de nata in Coimbra, and fresh seafood in Peniche.
