La Coruña, the largest city in Spain's Galicia region, is among the country's busiest ports. The remote Galicia area is tucked into the northwest corner of the Iberian Peninsula, surprising visitors with its green and misty countryside that is so much unlike other parts of Spain. The name "Galicia" is Celtic in origin, for it was the Celts who occupied the region around the 6th-century BC and erected fortifications. La Coruña was already considered an important port under the Romans. They were followed by an invasion of Suevians, Visigoths and, much later in 730, the Moors. It was after Galicia was incorporated into the Kingdom of Asturias that the epic saga of the Pilgrimage to Santiago (St. James) began. From the 15th century, overseas trade developed rapidly; in 1720, La Coruña was granted the privilege of trading with America - a right previously only held by Cadiz and Seville. This was the great era when adventurous men voyaged to the colonies and returned with vast riches. Today, the city's significant expansion is evident in three distinct quarters: the town centre located along the isthmus; the business and commercial centre with wide avenues and shopping streets; and the "Ensanche" to the south, occupied by warehouses and factories. Many of the buildings in the old section feature the characteristic glazed façades that have earned La Coruña the name "City of Crystal." Plaza Maria Pita, the beautiful main square, is named after the local heroine who saved the town in 1589 when she seized the English standard from the beacon and gave the alarm, warning her fellow townsmen of the English attack.

Believed to be the oldest town on the Iberian Peninsula, the Andalusian port of Cádiz enjoys a stunning location at the edge of a six-mile promontory. The town itself, with 3,000 years of history, is characterised by pretty white houses with balconies often adorned with colourful flowers. As you wander around be sure to take a stroll through the sizeable Plaza de Espãna, with its large monument dedicated to the first Spanish constitution, which was signed here in 1812. Cádiz has two pleasant seafront promenades which boast fine views of the Atlantic Ocean, and has a lovely park, the Parque Genoves, located close to the sea with an open-air theatre and attractive palm garden. Also notable is the neo-Classical cathedral, capped by a golden dome.

As you sail into Malaga you will notice what an idyllic setting the city enjoys on the famous Costa del Sol. To the east of this provincial capital, the coast along the region of La Axarqua is scattered with villages, farmland and sleepy fishing hamlets - the epitome of traditional rural Spain. To the west stretches a continuous city where the razzmatazz and bustle creates a colourful contrast that is easily recognisable as the Costa del Sol. Surrounding the region, the Penibéetica Mountains provide an attractive backdrop overlooking the lower terraced slopes which yield olives and almonds. This spectacular mountain chain shelters the province from cold northerly winds, giving it a reputation as a therapeutic and exotic place in which to escape from cold northern climes. Malaga is also the gateway to many of Andalusia's enchanting historic villages, towns and cities.

The provincial capital of the Valencian Community serves as a gateway to the huge influx of tourists that flock to the Costa Blanca resorts every year. Alicante is popular with holidaymakers who arrive for the warm, Mediterranean climate and seemingly endless golden beaches. However, there is much more to this city than sand and sun. With a picturesque waterfront, a hugely impressive castle, buzzing nightlife and a rich, complex history, Alicante is a fascinating destination all year round.

If you look north of the cathedral (La Seu, or the seat of the bishopric, to Mallorcans) on a map of the city of Palma, you can see around the Plaça Santa Eulàlia a jumble of tiny streets that made up the earliest settlement. Farther out, a ring of wide boulevards traces the fortifications built by the Moors to defend the larger city that emerged by the 12th century. The zigzags mark the bastions that jutted out at regular intervals. By the end of the 19th century, most of the walls had been demolished; the only place where you can still see the massive defenses is at Ses Voltes, along the seafront west of the cathedral.A torrent (streambed) used to run through the middle of the old city, dry for most of the year but often a raging flood in the rainy season. In the 17th century it was diverted to the east, along the moat that ran outside the city walls. Two of Palma's main arteries, La Rambla and the Passeig d'es Born, now follow the stream's natural course. The traditional evening paseo (promenade) takes place on the Born.If you come to Palma by car, park in the garage beneath the Parc de la Mar (the ramp is just off the highway from the airport, as you reach the cathedral) and stroll along the park. Beside it run the huge bastions guarding the Almudaina Palace; the cathedral, golden and massive, rises beyond. Where you exit the garage, there's a ceramic mural by the late Catalan artist and Mallorca resident Joan Miró, facing the cathedral across the pool that runs the length of the park.If you begin early enough, a walk along the ramparts at Ses Voltes from the mirador beside the cathedral is spectacular. The first rays of the sun turn the upper pinnacles of La Seu bright gold and then begin to work their way down the sandstone walls. From the Parc de la Mar, follow Avinguda Antoni Maura past the steps to the palace. Just below the Plaça de la Reina, where the Passeig d'es Born begins, turn left on Carrer de la Boteria into the Plaça de la Llotja (if the Llotja itself is open, don't miss a chance to visit—it's the Mediterranean's finest Gothic-style civic building). From there stroll through the Plaça Drassana to the Museu d'Es Baluard, at the end of Carrer Sant Pere. Retrace your steps to Avinguda Antoni Maura. Walk up the Passeig d'es Born to Plaça Joan Carles I, then right on Avenida de La Unió.

Since being designated a European Capital of Culture for 2013, with an estimated €660 million of funding in the bargain, Marseille has been in the throes of an extraordinary transformation, with no fewer than five major new arts centers, a beautifully refurbished port, revitalized neighborhoods, and a slew of new shops and restaurants. Once the underdog, this time-burnished city is now welcoming an influx of weekend tourists who have colonized entire neighborhoods and transformed them into elegant pieds-à-terre (or should we say, mer). The second-largest city in France, Marseille is one of Europe's most vibrant destinations. Feisty and fond of broad gestures, it is also as complicated and as cosmopolitan now as it was when a band of Phoenician Greeks first sailed into the harbor that is today's Vieux Port in 600 BC. Legend has it that on that same day a local chieftain's daughter, Gyptis, needed to choose a husband, and her wandering eyes settled on the Greeks' handsome commander Protis. Her dowry brought land near the mouth of the Rhône, where the Greeks founded Massalia, the most important Continental shipping port in antiquity. The port flourished for some 500 years as a typical Greek city, enjoying the full flush of classical culture, its gods, its democratic political system, its sports and theater, and its naval prowess. Caesar changed all that, besieging the city in 49 BC and seizing most of its colonies. In 1214 Marseille was seized again, this time by Charles d'Anjou, and was later annexed to France by Henri IV in 1481, but it was not until Louis XIV took the throne that the biggest transformations of the port began; he pulled down the city walls in 1666 and expanded the port to the Rive Neuve (New Riverbank). The city was devastated by plague in 1720, losing more than half its population. By the time of the Revolution, Marseille was on the rebound once again, with industries of soap manufacturing and oil processing flourishing, encouraging a wave of immigration from Provence and Italy. With the opening of the Suez Canal in 1869, Marseille became the greatest boomtown in 19th-century Europe. With a large influx of immigrants from areas as exotic as Tangiers, the city quickly acquired the multicultural population it maintains to this day.

The infinite variety of street life, the nooks and crannies of the medieval Barri Gòtic, the ceramic tile and stained glass of Art Nouveau facades, the art and music, the throb of street life, the food (ah, the food!)—one way or another, Barcelona will find a way to get your full attention. The capital of Catalonia is a banquet for the senses, with its beguiling mix of ancient and modern architecture, tempting cafés and markets, and sun-drenched Mediterranean beaches. A stroll along La Rambla and through waterfront Barceloneta, as well as a tour of Gaudí's majestic Sagrada Famíliaand his other unique creations, are part of a visit to Spain's second-largest city. Modern art museums and chic shops call for attention, too. Barcelona's vibe stays lively well into the night, when you can linger over regional wine and cuisine at buzzing tapas bars.
