14-Day Western Mediterranean: Lisbon Overnight

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.

Find your way in the city that launched the Age of Discovery. Cross the River Tagus on its soaring suspension bridge, watched over by a colossal statue of Christ. Wander the maze of streets in the Alfama, the old Moorish quarter, dominated by the medieval Castle of St George where peacocks strut and shriek. Stroll the Baixa and refuse to leave without a pair of elegant shoes.

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 fortifications and a beach—the picturesque and famous La Caleta.

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 Barcelona by car or train, luxury outlets, cava wineries, a mountaintop abbey and the sandy beaches of the Mediterranean coast await.

Famous for paella at Pepica's, favorite of Ernest Hemingway when he came to Valencia for bullfight festivals. Overlooking the Gulf of Valencia and the Balearic Islands, this Spanish jewel blends ancient and new in its historic center, where the Barrio del Carmen neighborhood uses the old walls of the city in its more modern structures. Walk the cobblestone streets to the chic Colon Street, home to local boutiques-or take in the sublime views from Las Arenas beach or one of the many delightful plazas. Sample shore excursions: Valencia City Tour.

There are more than two millennia of history to embrace in this port city in Spain's southeastern Murcia region. While Cartagena is famously home to the second-largest Roman amphitheater on the Iberian Peninsula, the city is much more than just spectacular ancient ruins. In addition to Cartagena’s architecture—along with that amphitheater, there are striking Art Nouveau buildings, neoclassical churches and ultramodern edifices throughout the city—you’ll find many opportunities to shop for local and regional artisan wares. In the city, investigate the restored medieval fortress looking out on the bay from the city’s highest point. Or take a short trip by car or bus to the historic Agrupa Vicenta Mines, the remarkable palm forest at Elche and the holy city of Caravaca. And the food of sunny Murcia! Friendly tapas bars with breezy terraces invite lingering over drinks, coffee or snacks. The local restaurants offer more than typical Spanish tapas on the menu—michirones (a spicy Murcian bean stew) and local spins on paella are widely available and worth a try. Grilled octopus, fried calamari, mussels and the freshest fish are some of the tasty benefits of the city’s perch beside the sea.

This strategic link between the Atlantic and the Mediterranean has been ruled by the Spanish, British and Moors. As long as the Barbary Apes remain, the British will rule Gibraltar this is the tradition that has held for 350 years. These pesky primates are a favorite with visitors despite their incessant chatter and light-fingered ways. Ride to the top of the Rock for great views over the Strait of Gibraltar-on a clear day you'll see Africa.

Dover, in the county of Kent in southeast England, has understandably been one of the most important ports of entry to the country for centuries, given its location on the English Channel across from France. The famous White Cliffs of Dover greet you as you arrive, and the city has a number of historic sights, including a medieval castle. For many travelers, however, it is primarily a gateway to London. Few places can compete with England’s capital for sheer energy, atmosphere and variety. London’s vibrancy—in art, in music, in architecture—is formidable. It’s a city with not only multiple attractions, grand structures and great cultural institutions (though there are plenty of those) but also scenic parks, walkable villages and striking modern additions.Culinary pioneers are reviving traditional techniques and introducing menus that are at the forefront of the world’s premier restaurant experiences. Leg-powered sightseeing (by bike or on foot) around London maximizes opportunities for stumbling across secret alleys, courtyards housing quirky art galleries and tiny old pubs serving fresh British ales. Shoppers will want to check out the items at some of the retail emporiums known the world over as well as diminutive boutiques stocking unique souvenirs.
