Spend a fabulous day in Seville visiting the magnificent cathedral, climbing the famed Giralda Tower and strolling through the gorgeous Alcazar and its gardens. See the ceramic-encrusted Plaza de España and stroll through the alleys of Barrio de Santa Cruz. Or explore the Andalusian wine country and Jerez, the home of sherry. Don't miss the charm of Cádiz with its gracious squares, its flower-filled parks on the city bastions and its bustling markets.
