Spread over a string of seven hills north of the Rio Tejo (Tagus River) estuary, Lisbon presents an intriguing variety of faces to those who negotiate its switchback streets. In the oldest neighborhoods, stepped alleys whose street pattern dates back to Moorish times are lined with pastel-color houses decked with laundry; here and there, miradouros (vantage points) afford spectacular river or city views. In the grand 18th-century center, calçada à portuguesa (black-and-white mosaic cobblestone) sidewalks border wide boulevards. Elétricos (trams) clank through the streets, and blue-and-white azulejos (painted and glazed ceramic tiles) adorn churches, restaurants, and fountains.

Of course, parts of Lisbon lack charm. Even some downtown areas have lost their classic Portuguese appearance as the city has become more cosmopolitan: shiny office blocks have replaced some 19th- and 20th-century art nouveau buildings. And centenarian trams share the streets with "fast trams" and noisy automobiles.

Lisbon bears the mark of an incredible heritage with laid-back pride. In preparing to host the 1998 World Exposition, Lisbon spruced up public buildings, overhauled its subway system, and completed an impressive second bridge across the river. Today the former Expo site is an expansive riverfront development known as Parque das Nações, and the city is a popular port of call for cruises, whose passengers disembark onto a revitalized waterfront. Downtown, all the main squares have been overhauled one by one.

In its heyday in the 16th century, Lisbon was a pioneer of the first wave of globalization. Now, the empire is striking back, with Brazilians and people from the former Portuguese colonies in Africa enriching the city’s ethnic mix. There are also more than a few people from other European countries who are rapidly becoming integrated.

But Lisbon's intrinsic, slightly disorganized, one-of-a-kind charm hasn't vanished in the contemporary mix. Lisboetas (people from Lisbon) are at ease pulling up café chairs and perusing newspapers against any backdrop, whether it reflects the progress and commerce of today or the riches that once poured in from Asia, South America, and Africa. And quiet courtyards and sweeping viewpoints are never far away.

Despite rising prosperity (and costs) since Portugal entered the European Community in 1986, and the more recent tourism boom, prices for most goods and services are still lower than most other European countries. You can still find affordable places to eat and stay, and with distances between major sights fairly small, taxis are astonishingly cheap. All this means that Lisbon is not only a treasure chest of historical monuments, but also a place where you won’t use up all your own hard-earned treasure.

Lively, commercial Oporto is the second largest city in Portugal after Lisbon. Also called Porto for short, the word easily brings to mind the city's most famous product - port wine. Oporto's strategic location on the north bank of the Douro River has accounted for the town's importance since ancient times. The Romans built a fort here where their trading route crossed the Douro, and the Moors brought their own culture to the area. Oporto profited from provisioning crusaders en route to the Holy Land and enjoyed the riches from Portuguese maritime discoveries during the 15th and 16th centuries. Later, port wine trade with Britain compensated for the loss of the spice trade and the end of gold and gem shipments from Brazil. In the 19th century, the city went through a period of new prosperity with the rise of industries. In its wake followed the building of workers' quarters and opulent residences. Since the declaration of Oporto as a World Heritage Site by UNESCO, the city aims to build up a cultural reference that will provide it with a new image, based on deep historical roots. Among the attractions that make Oporto such an interesting place are its graceful bridges spanning the Douro River, a picturesque riverfront quarter and, most notable, its world-famous port wine lodges. Although Oporto is a bustling centre and home to many different businesses, the source of its greatest fame is the rich, sweet fortified red wine we know as port.

The most important fishing port in Spain dates back to Roman times. From the 16th to 18th centuries, its active commercial trade with North America attracted English buccaneers to its waters in search of treasures from the galleons returning with riches from the Spanish colonies. In 1589, Francis Drake attacked the harbor and sacked the town. In the 19th century, modern Vigo was born and became rapidly one of the largest cities in Galicia. Vigo enjoys a beautiful setting surrounded by pinewoods and gardens. The town is built in an amphitheater around the south bank of the deep harbor, and its entrance is guarded by the Cies Islands. The old town and fishermen’s quarter are worth exploring as is Mount Castro, crowned by a castle fortress which commands a magnificent view of Vigo and the bay.

Days at sea are the perfect opportunity to relax, unwind and catch up with what you’ve been meaning to do. So whether that is going to the gym, visiting the spa, whale watching, catching up on your reading or simply topping up your tan, these blue sea days are the perfect balance to busy days spent exploring shore side.

Casablanca is Morocco's most modern city, and various groups of people call it home: hardworking Berbers who came north from the Souss Valley to make their fortune; older folks raised on French customs during the protectorate; devoted Muslims; wealthy business executives in the prestigious neighborhoods of California and Anfa; new and poor arrivals from the countryside, living in conspicuous shantytowns; and thousands of others from all over the kingdom who have found jobs here. There is also a fair-size expat population, including many French people. The city has its own stock exchange, and working hours tend to transcend the relaxed pace kept by the rest of Morocco.

True to its name—casa blanca in Spanish (white house), which, in turn, is Dar el-Beida in Arabic—Casablanca is a conglomeration of white buildings. The present city, known colloquially as "Casa" or "El Beida," was only founded in 1912. It lacks the abundance of ancient monuments that resonate in Morocco's other major cities; however, there are still some landmarks, including the famous Hassan II Mosque.

Many first-time visitors may find the Tangier port such a rude awakening that they fail to see the beauty of the place. Mobs of bona fide hustlers greet the arriving ferries hungry for fresh greenhorns to fleece in any way they can. Simply walk quickly past these unsolicited assistants, pretend you know exactly where you're going, and show no sign that you're bewildered. Once you hit your stride and start going places with confidence, Tangier has a charm that this raucous undercurrent only enhances: crumbling Kasbah walls, intimate corners in the serpentine medina, piles of bougainvillea, French balconies, Spanish cafés, and other remnants of times gone by. Tangier is a melting pot—a place where it's not uncommon to see sophisticated Moroccans sharing sidewalks with rural Rifi Berbers. Travelers from around the world all converge on the African continent's nearest point eager for a look into a cultural potpourri that has taken thousands of years to blend.

Málaga is one of southern Spain’s most welcoming and happening cities, and it more than justifies a visit. Visitor figures have soared since the Museo Picasso opened in 2003 and a new cruise-ship terminal opened in 2011, and much of the city has had a well-earned face-lift, with many of its historic buildings restored or undergoing restoration. The area between the river and the port is being spruced up and transformed into the Málaga Arte Urbano Soho (MAUS Art District), and in 2015 three new art museums opened, underlining the city's aim to become one of southern Europe's centers for art. Alongside all this rejuvenation, some great shops, and lively bars and restaurants have sprung up all over the center.

True, the approach from the airport certainly isn’t that pretty, and you'll be greeted by huge 1970s high-rises that march determinedly toward Torremolinos. But don’t give up: in its center and eastern suburbs, this city of about 550,000 people is a pleasant port, with ancient streets and lovely villas amid exotic foliage. Blessed with a subtropical climate, it's covered in lush vegetation and averages some 324 days of sunshine a year.

Central Málaga lies between the Guadalmedina River and the port, and the city’s main attractions are all here. The Centro de Arte Contemporáneo sits next to the river; to the east lies the MAUS district, slowly being hoisted from its former seedy red-light reputation to a vibrant cultural hub with galleries and up-and-coming restaurants. Around La Alameda boulevard, with its giant weeping fig trees, is old-town Málaga: elegant squares, pedestrian shopping streets such as Calle Marqués de Larios, and the major monuments, which are often tucked away in labyrinthine alleys.

Eastern Málaga starts with the pleasant suburbs of El Palo and Pedregalejo, once traditional fishing villages. Here you can eat fresh fish in the numerous chiringuitos and stroll Pedregalejo's seafront promenade or the tree-lined streets of El Limonar. A few blocks inland is Málaga's bullring, La Malagueta, built in 1874, and continuing west, Muelle Uno (port-front commercial center), whose striking glass cube is now home to the Centre Pompidou. It's great for a drink and for soaking up views of the old quarter.

With the Atlantic Ocean on three sides, Cádiz is a bustling town that's been shaped by a variety of cultures, and has the varied architecture to prove it. Founded as Gadir by Phoenician traders in 1100 BC, Cádiz claims to be the oldest continuously inhabited city in the Western world. Hannibal lived in Cádiz for a time, Julius Caesar first held public office here, and Columbus set out from here on his second voyage, after which the city became the home base of the Spanish fleet. In the 18th century, when the Guadalquivir silted up, Cádiz monopolized New World trade and became the wealthiest port in Western Europe. Most of its buildings—including the cathedral, built in part with wealth generated by gold and silver from the New World—date from this period. The old city is African in appearance and immensely intriguing—a cluster of narrow streets opening onto charming small squares.
