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.

Tangier can trace its origins back to the Phoenicians and ancient Greeks. It was named after Tinge, the mother of Hercules’ son, and its beginnings are embedded in mythology. It was subsequently a Roman province, and after Vandal and Byzantine influences, was occupied by the Arabs with Spain, Portugal, France and England also playing a part in the city’s history. With such a diverse past it is perhaps not surprising that Tangier is such an individual city. Overlooking the Straits of Gibraltar, the city lies on a bay between two promontories. With its old Kasbah, panoramic views, elegant buildings, squares and places of interest, there is much to discover in both the new and old parts of the city.

Perhaps the prettiest of the Canary Islands, Gran Canaria is an almost circular isle with the peak of Pozo de Las Nieves, its highest point, at the centre. With a wealth of natural beauty and all the exciting attractions of city life in the capital, the island offers the best of both worlds. You will no doubt wish to see the sights of the capital’s old quarter, which dates back to the 15th century and encompassses the Vegueta and Triana districts, and wherever you go you can enjoy the glorious subtropical climate, perfect for growing exotic palms and fruits.

According to Salvador's adopted son Jorge Amado, "In Salvador, magic becomes part of the every-day." From the shimmering golden light of sunset over the Baía do Todos os Santos, to the rhythmic beats that race along the streets, Salvador, while no longer Brazil's capital, remains one of its most captivating cities. A large dose of its exoticism comes down to its African heritage—at least 70% of its 2,675,000 population is classified as Afro-Brazilian—and how it has blended into Brazil's different strands, from the native Indians to the Christian colonizers. Salvadorans may tell you that you can visit a different church every day of the year, which is almost true—the city has about 300. Churches whose interiors are covered with gold leaf were financed by the riches of the Portuguese colonial era, when slaves masked their traditional religious beliefs under a thin Catholic veneer. And partly thanks to modern-day acceptance of those beliefs, Salvador has become the fount of Candomblé, a religion based on personal dialogue with the orixás, a family of African deities closely linked to nature and the Catholic saints. The influence of Salvador's African heritage on Brazilian music has also turned the city into one of the musical capitals of Brazil, resulting in a myriad of venues to enjoy live music across the city, along with international acclaim for exponents like Gilberto Gil, Caetano Veloso, and Daniela Mercury. Salvador's economy today is focused on telecommunications and tourism. The still-prevalent African culture draws many tourists—this is the best place in Brazil to hear African music, learn or watch African dance, and see capoeira, a martial art developed by slaves. In the district of Pelourinho, many colorful 18th- and 19th-century houses remain, part of the reason why this is the center of the tourist trade. Salvador sprawls across a peninsula surrounded by the Baía de Todos os Santos on one side and the Atlantic Ocean on the other. The city has about 50 km (31 miles) of coastline. The original city, referred to as the Centro Histórica (Historical Center), is divided into the Cidade Alta (Upper City), also called Pelourinho, and Cidade Baixa (Lower City). The Cidade Baixa is a commercial area—known as Comércio—that runs along the port and is the site of Salvador's indoor market, Mercado Modelo. You can move between the upper and lower cities on foot, via the landmark Elevador Lacerda, behind the market, or on the Plano Inclinado, a funicular lift, which connects Rua Guindaste dos Padres on Comércio with the alley behind Cathedral Basílica. From the Cidade Histórica you can travel north along the bay to the hilltop Igreja de Nosso Senhor do Bonfim. You can also head south to the point, guarded by the Forte Santo Antônio da Barra, where the bay waters meet those of the Atlantic. This area on Salvador's southern tip is home to the trendy neighborhoods of Barra, Ondina, and Rio Vermelho, with many museums, theaters, shops, and restaurants. Beaches along the Atlantic coast and north of Forte Santo Antônio da Barra are among the city's cleanest. Many are illuminated at night and have bars and restaurants that stay open late.

Welcome to the Cidade Maravilhosa, or the Marvelous City, as Rio is known in Brazil. Synonymous with the girl from Ipanema, the dramatic views from Christ the Redeemer atop Corcovado mountain, and fabulously flamboyant Carnival celebrations, Rio is a city of stunning architecture, abundant museums, and marvelous food. Rio is also home to 23 beaches, an almost continuous 73-km (45-mile) ribbon of sand.As you leave the airport and head to Rio's beautiful Zona Sul (the touristic South Zone), you'll drive for about 40 minutes on a highway from where you'll begin to get a sense of the dramatic contrast between beautiful landscape and devastating poverty. In this teeming metropolis of 12 million people (6.2 million of whom live in Rio proper), the very rich and the very poor live in uneasy proximity. You'll drive past seemingly endless cinder-block favela, but by the time you reach Copacabana's breezy, sunny Avenida Atlântica—flanked on one side by white beach and azure sea and on the other by condominiums and hotels—your heart will leap with expectation as you begin to recognize the postcard-famous sights. Now you're truly in Rio, where cariocas (Rio residents) and tourists live life to its fullest.Enthusiasm is contagious in Rio. Prepare to have your senses engaged and your inhibitions untied. Rio seduces with a host of images: the joyous bustle of vendors at Sunday's Feira Hippie (Hippie Fair); the tipsy babble at sidewalk cafés as patrons sip their last glass of icy beer under the stars; the blanket of lights beneath the Pão de Açúcar (Sugarloaf Mountain); the bikers, joggers, strollers, and power walkers who parade along the beach each morning. Borrow the carioca spirit for your stay; you may find yourself reluctant to give it back.

Uruguay’s capital city hugs the eastern bank of the Río de la Plata. A massive coastal promenade (malecón) that passes fine beaches, restaurants, and numerous parks recalls the sunny sophistications of the Mediterranean and is always dotted with Montevideans strolling, exercising, and lounging along the water. Montevideo has its share of glitzy shopping avenues and modern office buildings, balanced with its historic old city and sumptuous colonial architecture, as well as numerous leafy plazas and parks. It is hard not to draw comparisons to its sister city Buenos Aires across the river, and indeed Montevideo strikes many as a calmer, more manageable incarnation of Argentina's capital.When the weather's good, La Rambla, a 22-km (14-mile) waterfront avenue that links the Old City with the eastern suburbs and changes names about a dozen times, gets packed with fishermen, ice-cream vendors, and joggers. Around sunset, volleyball and soccer games wind down as couples begin to appear for evening strolls. Polls consistently rate Montevideo as having the highest quality of life of any city in Latin America. After one visit here, especially on a lovely summer evening, you probably will agree.

Glamorous and gritty, Buenos Aires is two cities in one. What makes Argentina's capital so fascinating is its dual heritage—part European, part Latin American. Plaza de Mayo resembles a grand square in Madrid, and the ornate Teatro Colón would not be out of place in Vienna. But you’ll know you’re in South America by the leather shoes for sale on cobbled streets and impromptu parades of triumphant soccer fans. Limited-production wines, juicy steaks, and ice cream in countless flavors are among the old-world imports the city has perfected.
