Blessed with a dramatic setting on the steep banks of the river Douro, Portugal’s second city is currently enjoying something of a renaissance, and is best known as the home of the country’s most famous export, port wine.

The Galician city of Ferrol, birthplace of General Franco, doesn’t feature on too many tourist itineraries, though maritime enthusiasts may enjoy a visit to the 18th-century shipyards. Most cruise visitors will use Ferrol as a base to explore Galicia’s wild coast, the nearby city of La Coruña or the famous pilgrimage site of Santiago de Compostela.

Gijón is the largest city in the Asturias region of northern Spain, an important industrial port but also a lively and youthful place, ideally positioned for exploring the Costa Verde. The most interesting area is the historic fishing village of Cimadevilla, which sits on a peninsula that divides the bay in two.

Bordeaux sits at the centre of the world's most famous wine region, and is home to a beguiling blend of beautiful buildings, sophisticated gastronomy and high culture. It's a marvellous place to spend some time, whether it's a day sampling wines, an evening at the opera or a night on the tiles.

Douarnenez is synonymous with all things maritime, a bustling Breton port with four different harbours. In its 19th-century heyday Douarnenez grew prosperous from sardine fishing, and its modern attractions include an excellent maritime museum, with boats and tall ships from around the world.

Saint-Malo grew rich off the back of maritime trade and its plundering corsairs, a seafaring heritage that is still proudly on display today. It’s great fun getting lost in the streets of the walled old town, and the famous medieval abbey of Mont Saint-Michel is an easy day-trip.

The old Frisian port of Harlingen, on the shores of the Wadden Sea, is centred around an attractive cluster of canals and historic buildings. Ferries depart from here for the islands of Terschelling and Vlieland, while nearby Franeker is home to the world’s oldest working planetarium, dating back to the 18th century.
