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.

Holyhead is best known as the departure point for ferries to Ireland, but it’s also the gateway to the enchanting island of Anglesey. This green and ancient land was once a druid stronghold, and the rugged landscape is crowned with some of the most beautiful castles in Wales.

Disagreements over the correct name for Northern Ireland’s second city date back to 1613, and are unlikely to be resolved any time soon, so let’s focus instead on what the city has to offer. Highlights include the 17th century city walls, a vibrant live music scene and a city centre rejuvenated by Derry’s stint as UK Capital of Culture in 2013. (Greencastle is actually in the Republic, but it's a short drive south to Derry.)

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.

An important naval base and major commercial port, Cherbourg is the gateway to the many attractions of Normandy, including the Bayeux Tapestry and the beaches where the D-Day landings took place. Cherbourg’s excellent Cité de la Mer maritime museum is also well worth a visit.

White Cliffs Country is a fascinating region, one packed with history and natural beauty. We think there is no sight like that of the stunning cliffs rising from the sea, topped by the fortifications of Dover Castle, and surrounded by lush green countryside.

Antwerp is a city bound up with the arts, once home to the likes of Rubens and Van Dyck, and more recently carving out a reputation as the fashion capital of Belgium. It’s also a magnet for shopaholics, with designer boutiques and jewellers galore.

One of the great ports of Europe, Rotterdam’s impressive skyline can be seen from far and wide. With great architecture both ancient and modern, fantastic exhibition and concert halls, theatres, pretty galleries and numerous museums, there is so much to do when you stay here.

You might not expect to find a beach resort in Norway, but the sunny city of Kristiansand is where Norwegians go for a spot of fun by the seaside. There are plenty of family-friendly attractions, including a zoo, and it’s also a good base for exploring the pretty fishing villages of the south coast.

The intriguing city of Oslo, Norway’s capital, has so much to offer, from the open air Norwegian Folk Museum to the amazing Vigeland sculpture park, and from the Holmenkollen Ski Museum to the Munch Museum’s collection of memorable paintings. History, art and culture are what defines this lovely city.

Gothenburg, Sweden’s laid back second city, is a delightful mix of cobbled streets, neoclassical architecture and picturesque canals. The old town is full of history, with some interesting museums, and the thriving arts scene has helped to revitalise the city’s previously run-down industrial districts.

Wonderful Copenhagen is the perfect city to explore on foot, by bicycle or by water. Visit the bustling wharf at Nyhavn, enjoy the palaces, galleries and museums, wander through the amazing Tivoli Gardens, and if you have time, make the most of Copenhagen’s gastronomic revolution.

The former Hanseatic port of Wismar is one of the Baltic’s lesser known gems. The town was under Swedish control for most of the 16th and 17th centuries, and there are still many reminders of this period as you stroll around the pretty UNESCO-listed old town, with its cobbled streets and gabled facades.
