Often called the gateway to Europe, the port city of Rotterdam is full of old-world charm. The harbor offers amazing views and a maze of wharves and canals, along with towering spires make for a beautiful sight. Take a stroll and duck into one of the pubs or eateries along the way. Only three pre World War II buildings in the city centre have survived and are worth a look - city hall, St. Laurence church and the White House. Explore the Museum Boymans van Beuningen, which houses a unique collection dating from the 14th century, or the Museum Voor Volkenkunde - home to ethnological exhibits. Exquisite architecture can be seen in many areas of Rotterdam, most notably in the Delfshaven quarter of the city - where 18th century houses are on display. For a laugh, check out Kijk-Kubus, an upside-down house.

Casablanca is Morocco's largest city and its most important port. While Rabat is the country's official capital, Casablanca is its economic and cultural hub, the place where Moroccans go to make it big. There has been a settlement here since before the Romans, and although the Barbary pirates and Portuguese also left their marks, it wasn't until the French colonial period that Casablanca truly came into its own. The modern city was the first in the world to be laid out by aerial survey, and was barely 20 years old when its name was framed forever in the Hollywood classic of the same name. But Casablanca isn't just a place for movie nostalgia—its tremendous Hassan II Mosque puts Moroccan tradition on a distinctly modern trajectory, while its trams whisk you past Art Deco architecture to Dubai-inspired malls and city beaches. Casablanca's central location on the Atlantic coast also means that day trips to the historic imperial cities of Marrakech and Rabat are an easy option. We suggest…

Regardless of when you visit Agadir, on Morocco’s Atlantic Coast, your chances of arriving on a sunny day are pretty high. That selling point has made it a popular seaside resort for Europeans, who stroll along the promenade and surf, wet bike and ride camels on the seemingly endless crescent-shaped beach. Here, you can sip a cup of Berber tea at a café, grab a pint at a pub or dine and dance at one of the beach clubs. Beyond the beach, much of the area’s history has been erased, and all that can be seen today are modern whitewashed buildings and palm-lined boulevards. (Though it was the site of an ancient Roman port and occupied by both the French and the Portuguese, Agadir was almost completely destroyed by an earthquake in 1960 and little of its past survived.) You can still explore the region’s heritage at the Amazigh Museum, which provides an introduction to Berber culture, and the hilltop casbah, built in the 16th century. Don’t miss the souks, with local products like saffron,…

Enjoy strolling on Puerto del Rosario's sandy beaches, or wander through the harbour area, the oldest part of town. From here you can find all of the small alleys lined with old Canarian style houses.

Las Palmas is a capital of Gran Canaria, one of Spain's Canary Islands off northwestern Africa. A major cruise-ship port, the city is known for duty-free shopping and for its sandy beaches. At Playa de Las Canteras, a coral barrier lines the beach and shelters swimmers.

A visit to the wild island of La Palma—the most northern and westerly of the Canary Islands—is about as close as it gets to visiting Jurassic Park. Prehistoric junglelike forests with wispy waterfalls and babbling streams blanket the north of the isle, while the south feels dry and scorched with simmering dormant volcanoes. The craggy coastline and black-sand beaches sit below the soaring ridgeline of the eight-kilometer-wide (five-mile-wide) Caldera de Taburiente. It’s no wonder the entire island was classified as a UNESCO Biosphere Reserve in 2002. Exploring nature should be priority number one when visiting La Palma, but it’s impossible to understand the island’s culture without a visit to Santa Cruz, La Palma’s second-largest city and its only port. Its claim to fame—other than being the birthplace of the world-famous shoe designer Manolo Blahnik—is its clutch of colorful colonial buildings with traditional Canarian wooden balconies. Wandering down Calle O’Daly (also called Calle…

Though part of Spain, the Canary Islands sit in the open Atlantic Ocean, about 100 kilometers (60 miles) west of Morocco. The mild climate mixed with a rich volcanic landscape and beautiful sandy beaches makes the main city of Santa Cruz, on the largest island of Tenerife, a welcome stop for many cruise voyages. The isolated island is dominated by the Teide volcano, the tallest mountain in Spain and site of one of the world’s most popular national parks. A cable car carries visitors to the top, offering unrivaled views of the island. Travelers interested in learning about the history of the island, its unique wildlife and the population of indigenous people that lived here before the arrival of European settlers should visit the Museum of Nature and Man in Santa Cruz, while architecture buffs can stroll the streets of La Laguna to see colonial-era mansions. And travelers keen on food and wine should venture into the countryside to sample local dishes or make the drive to Casa del Vino…

Hanging off the southwestern edge of Spain, Cádiz is one of Andalucía’s regional capitals and a place bursting with personality. Europe’s oldest continually inhabited city, with a history stretching back 3,000 years, has fallen on hard times in recent years, but a combination of pride, good humor and stoicism keeps it on an even keel. The famous Carnival, one of Spain’s most important in the genre, is a thrilling fiesta into which Cádiz pours all its energy and ingenuity. The city’s fond nickname, la tacita de plata ("little silver cup"), alludes to its curious geography—it juts out on a long peninsula into a sheltered bay. Old town Cádiz is a warren of cobbled streets where the houses, painted white or dusty ochre, have the weather-beaten look of a place subjected to centuries of wind and salt. This ancient city has one good example of everything that matters: a great food market, a theater (the Teatro Falla, a grand Art Nouveau Moorish gem), a gorgeous cathedral, impressive fortific…

Málaga is your chance to tour to the Moorish wonders of the Alhambra with its elaborate carvings, grand columns and delicate arches. Stalagmites and stalactites reach calcite fingers into the caverns of Nerja, near Malaga. 30,000 years ago, people lived in the shadowy recesses of these caves. In nearby Mijas, shop tables are laden with hand-made ceramics, and the people live in shuttered, whitewashed cottages.

On the northeast coast of Spain, overlooking the Mediterranean, Barcelona is a vibrant port city, packed with centuries of iconic art and architecture—Gaudí and Picasso both called it home—and lined with sunny white-sand beaches. Explore the Catalan capital's tourist attractions and historic neighborhoods, Modernisme and world-renowned art museums, galleries and local crafts shops—some of which are centuries old and stock traditional Catalan wares. After you see the sights, there are lively tapas bars around every corner where you can stop for a drink, a café amb llet (Catalan for espresso with steamed milk) or a snack, no matter the hour. Green spaces for picnics, long walks and respite from the hustle and bustle are scattered throughout Barcelona's attractions: There's Gaudí's mosaic-decorated park, a neoclassical maze at the Laberint d'Horta, as well as plenty of high places (mountains, monuments and edifices) where sightseeing visitors can take in the view. A short trip from Barce…
