We enjoyed the Mezquita, the Moorish mosque, later the cathedral of Cordoba, and the Alcazar and its beautiful ornamental gardens. Cool off in a fountain - they're all over the city and often provide relief for weary feet!
We liked strolling the narrow lanes of the Juderia, the old Jewish quarter, stopping off here and there to enjoy a sherry and some tapas.
Quick Tips:
Several of Cordoba's big attractions offer free entry on a Friday. We saved the entrance charges of three such places in one day.
Cordoba gets fiercely hot in summer. Try to visit the attractions early or later in the day, and do make sure you're not too far from a cool and shady place as the hottest part of the day nears (usually around 2 pm) – otherwise, you could find yourselves a long way from a cool drink.
Best Way To Get Around:
It is small enough to negotiate on foot. Bus service is cheap (.90 anywhere around the city), and the buses are frequent and easy to use.
