Bilbao

Late spring to early autumn suits sightseeing, though Atlantic rain can interrupt outdoor plans.

Mild, changeable Atlantic weather makes a waterproof jacket and adaptable layers useful.

Accommodation and dining vary widely; pintxos bars and public markets can moderate meal costs.

Metro, trams and buses cover the city well, but steep streets can complicate some journeys.

Explore the Guggenheim Museum, Casco Viejo, riverside promenade and Mercado de la Ribera.

Take normal urban precautions, particularly around busy nightlife areas and crowded transport.
