Step outside your hotel, for a stroll through the streets of the heart of the English-speaking world. In this city of nearly seven million, you'll see everything from 12th-century fortifications to modern skyscrapers, formal parks to punk rockers. Your Tour Director will lead you to some of the most famous sites. Walk along the Thames River. Cross Trafalgar Square. See bustling Piccadilly Circus. Pass trendy shops and cafés in Bohemian Soho on your way to Covent Garden, a 13th-century fruit and vegetable garden transformed into a maze of narrow streets and pedestrian walkways burgeoning with street performers, open-air markets and boutiques.

Nothing’s more British than fish and chips—there are eight fish and chip shops (“chippies”) for every McDonald’s in the country. Head to an authentic pub with your Tour Director for a taste of this national food, generally served with malt vinegar.

Join a licensed local guide for an in-depth look at London, from the royal haunt of Buckingham Palace (the official London residence of Queen Elizabeth II) to the slightly more democratic Speakers’ Corner of Hyde Park, where anyone can pull up a soapbox and orate to his heart’s content. You’ll see the changing of the guard (season permitting), the clock tower of Big Ben with its 14-ton bell, and Westminster Abbey, where almost every English king and queen since William the Conqueror has been crowned. After a stop at the Houses of Parliament, continue on to the magnificent St. Paul’s Cathedral, the masterpiece of London architect Christopher Wren.

Take the Eurostar under the English Channel. Faster than you can say... anything, in French, you'll whiz through a tunnel and arrive in Paris.

This city was made for walking. Stroll grand boulevards with sweeping views of the city, pristine parks with trees planted in perfect rows, and narrow streets crowded with vendors selling flowers, pastries and cheese. Your Tour Director will show you some of the most famous sites, including the ornate, 19th-century Opera, the Presidential residence, the ultra-chic shops of the Rue du Faubourg St-Honoré, and the gardens of the Tuileries. You'll pass the Place de la Concorde (that pointy thing in the middle is the Obelisk of Luxor, a gift from Egypt in 1836), and the Place Vendôme, a huge square surrounded by 17th-century buildings.

The world's largest art museum, the Louvre is housed in a medieval fortress-turned-castle so grand it's worth a tour itself. You walk through the 71-foot glass pyramid designed by I.M. Pei and added in 1989, and step into another world-one with carved ceilings, deep-set windows, and so many architectural details, you could spend a week just admiring the rooms. But check out the art on the walls. The Mona Lisa is here, as well as the Venus de Milo and Winged Victory (the headless statue, circa 200 BC, discovered at Samothrace). The Louvre has seven different departments of paintings, prints, drawings, sculptures and antiquities. Don't miss the Egyptian collection, complete with creepy sarcophagi, or the collection of Greek ceramics, one of the largest in the world. (Please note the Louvre is closed on Tuesdays.)

What's that huge white arch at the end of the Champs-Élysées? The Arc de Triomphe, commissioned by Napoleon in 1806 after his victory at Austerlitz. A licensed local guide will give the goods on this, and other, Parisian landmarks. Spot chic locals (and tons of tourists) strolling the Champs-Élysées. Look up at the iron girders of the Eiffel Tower, built for the 1889 World's Fair to commemorate the centenary of the French Revolution. See Les Invalides (a refuge for war wounded), the École Militaire (Napoleon's alma mater), and the Conciergerie (the prison where Marie Antoinette was kept during the French Revolution). Then head to the Île de la Cité -- a small island in the Seine -- to see Notre Dame Cathedral. Look up at the great gray spires, grotesque gargoyles, and huge, round stained-glass windows (even more impressive than in the Disney version of “The Hunchback of Notre Dame”).

The ultimate palace, Versailles was built by Louis VIX, and housed the royal family and its groveling court from 1582, when the Sun King moved in, to the French Revolution. Everything in Versailles is worth a look, from the 250-foot-long Hall of Mirrors, with themed salons-"war" and "peace"-on either side, to Marie Antoinette's faux country hamlet. When being a queen became too much to bear, she would pretend to be a commoner, tending her sheep and wearing peasant clothes. (Please note Versailles is closed on Mondays.)

See the city from the water on an hour-long cruise along the River Seine. The Seine cuts right through Paris, dividing the city in half. See the Eiffel tower rising up on the Left Bank, the walls of the Louvre on the Right Bank. A guide will point out other monuments and architectural marvels as you pass, many of which are illuminated by clear white light at night.

Before a backdrop of snow-capped Alpine mountains and green, cow-filled pastures, join a local licensed guide on a tour of Lucerne’s famous sights. Weave your way through a maze of narrow, winding streets until you reach the River Reuss and the medieval Kapellbrücke Bridge. Stop to marvel at the bridge walls, decorated with murals that recreate the 14th-century originals destroyed in a fire. Journey the cobblestone streets in the Old Town to see the Löwendenkmal (Lion Monument), the somber sandstone wild cat gazing down into a reflecting pool. Sense sheer courage as you ponder this artfully chiseled statue created to honor the Swiss Guards who died defending the Tuileries in 1792.

Scale snow-capped Mount Pilatus via the world’s steepest cog railway or cable car. Enjoy a bird’s eye view of Lucerne’s skyline and Alpine panoramas galore. Here’s your chance to snap some of the most frame-worthy photos. Keep your fingers crossed for a clear day when mountain-top views span as far as 200 miles. Or enjoy some free time exploring Lucerne. Stroll the shores of Lake Lucerne. Scour the cozy neighborhoods for frescoed homes with oriel windows. Or just stop and indulge your sweet tooth in some of the creamiest chocolate in the world. If that doesn’t satisfy your craving for adventure, see your Tour Director for more ideas.

Poised between two of Switzerland's prettiest lakes, beautiful Interlaken is one of the oldest tourist resorts in the country. Its cafes, shops, and hotels offer unparalleled views of the Jungfrau mountain.

A grim glimpse into the past, Dachau was the first of Nazi Germany’s camps and a model for the 3,000 work and concentration camps to come. Your Tour Director will lead you through the gas chamber (although never used) and crematorium, which have been restored as a chilling memorial to the 206,000 prisoners who were interned in the camp from 1933 to 1945. The museum examines pre-1930 anti-Semitism, the rise of the Nazi party, and photographed and documented lives of prisoners.

Join a professional licensed tour guide for a whirlwind look at Munich. Founded in the 12th century by Henry the Lion, Munich now roars with the hustle and bustle of modern German life. As you pass by Marienplatz (named after the square’s gilded Virgin Mary and Child statue), mechanical knights joust and coopers dance to the folk-music chimes of the Neues Rathaus’s Glockenspiel. The twin onion-bulb towers of the Frauenkirche Cathedral frame this whimsical display, while the scents, sounds, and colors of the nearby food market attempt to draw your attention elsewhere. Resist temptation and continue on to Olympiapark, a new suburb built for the 1972 Olympic Games. Pass by several museums, such as the BMW Museum, Alte Pinakothek (home to Munich’s most precious art collections), and the Deutsches Museum of science and technology.

Innsbruck’s backdrop of towering snow-capped mountains transform this down-to-earth cobblestoned city into a world class ski resort. Identical rustic white stuccoed homes trimmed in brown cluster in the Old Town, their colors blending into the surrounding landscape, while the glittering Little Golden Roof shelters the balcony where Maximilian I Habsburg and his love Bianca promised to stay together forever.

Bubbling up on more than 100 islands in a lagoon off the Adriatic, Venice is an absolutely unique and unquestionably beautiful city. The weight of its opulent architecture – bulbous domes, gothic spires, and lacy marble – may be sinking the city by 10 inches a century, but your local guide will make sure you don’t sink out of sight as you tour the intricate labyrinth of streets and bridges. Step into Piazza San Marco, an airy expanse of arches, sunlight, and pigeons. The multi-domed Basilica on one end, completed in 1094 but decorated for centuries afterward, is the final resting place of the apostle St. Mark, Venice’s patron saint. The mosaics beneath the basilica’s outside arches depict the arrival of St. Mark’s body, stolen from Egypt in 828 by Venetian traders. The frothy Venetian Gothic Doge’s Palace stands next door. Continue on to a glass-blowing demonstration. Venetian glass has long been considered the best in the world, and its production was such a state secret that during the Middle Ages, any Venetian glassblower who attempted to ply his trade outside the city was immediately arrested.

A small town of narrow streets and medieval walls, Assisi might never have been famous had it not been the birthplace of St. Francis, the founder of the Franciscan order. Today it is a major destination for religious pilgrims and art lovers alike. You’ll explore the Basilica of St. Francis, built in the 13th century to hold the saint’s body. Ironically, the body was hidden so well in the basilica that it took 600 years of digging to find it.

Baroque-en hearted? Revive your spirits with a walk past Rome's most beautiful and unusual Baroque fountains. At the foot of the Spanish Steps, elegant cafes once favored by visiting Brits and Americans surround the central fountain. The water pressure here was so low that the artist had to sink the fountain into the ground to get any water going through it, so he went ahead and designed the fountain to look like a sinking ship. There's no shortage of water pressure at the nearby Trevi Fountain, a Baroque extravagance designed by master sculptor Bernini. At the Pantheon you'll see the largest concrete dome ever constructed. An oculus, or hole, in the dome lets sunlight into the beautiful temple, dedicated to all the gods.

Gods and gladiators, glory and gore. Ancient Rome lives on in its spectacular monuments, flavoring the frenetic present with tastes of the past. Don a space-age Whisper headset to get the inside scoop on the most spectacular, the Colosseum, a grisly battle arena that seated more than 45,000. An enormous retractable roof awning system kept spectators cool on sunny days. The nearby Forum provides a glimpse into everyday ancient life, with markets, meeting places, and temples all combined into one vast space. Move into Christian Rome at St. Peter’s Basilica, the triumphal Renaissance church flanked by rows of columns radiating outward like welcoming arms. Within the church Michelangelo’s masterpieces are on display, the “Pietà” in the main church and the recently restored ceiling frescoes and “Last Judgment” in the Sistine Chapel. Continue your trek through time at Piazza Venezia, site of the enormous monument to Victor Emmanuel II, Italy’s first king, and of the Palazzo Venezia, where Mussolini set up his headquarters and from whose porch his mother was said to eavesdrop on citizens below. (The Sistine Chapel is closed on most religious holidays and Sundays, except for the last Sunday in each month).

With some of the most stunning Roman ruins in the region, Ostia Antica attracts visitors looking for a sneak peak into ancient life. Check out the mosaics in the Piazzale delle Corporazione, the commercial center, that indicate what each merchant sold. The House of Apulius shows details of ancient cult practices, while the Casa di Diana, a well-preserved private home, gives an intimate look into daily life. Don't miss the ancient café, where counters, shelves, and even seats wait for ancient customers.

Charming San Gimignano provides a glimpse into medieval Tuscany, from its jagged hilltop skyline to its well-preserved frescoes. The most impressive are inside the town's main church, where biblical stories from the Old and New Testaments line the walls. Inside the small Cappella di Santa Fina are stunning mosaics by Ghirlandaio depicting the life of a local saint within her hometown.

Immerse yourself in the charms of old-world Firenze, a red-brick splendor set in the rolling green hills of Tuscany. The birthplace and focal point of the Italian Renaissance, Florence still has the masterpieces to prove it. Brunelleschi’s elegant Duomo (dome) dominates the skyline, and around every corner is an architectural triumph filled with wall after wall of incomparable art. Your local licensed guide will take you to Giotto's Bell Tower and the aptly named Gates of Paradise, the bronze east doors of the Baptistery that spurred the burgeoning Renaissance. The boy guarding the Palazzo Vecchio with his slingshot is just a copy of Michelangelo’s David; the real statue is over at the Accademia. Don’t overlook the tombs of Michelangelo, Galileo, and Machiavelli at the Chiesa di Santa Croce, and definitely don’t overlook Florence’s amazing leather goods. Check them out when you visit one of the area’s famed workshops.

Founded in 1563, the Accademia was the first school in Europe established to teach drawing, painting, and sculpting. Michelangelo's David (the biblical hero who slayed Goliath) is the most famous work on display.

Stop in Pisa to see the famous leaning bell tower. It was already partly finished when builders realized that -- surprise! -- the ground beneath was too soft to support it. They tried to correct the tilt by putting a slight bend in the structure, but the extra weight just made it tilt more. Famous as it is, the leaning tower is just one component of Pisa’s Campo dei Miracoli (Field of Miracles). Rising from an immaculate green lawn, the baptistery, duomo, and tower are fine examples of Pisan Romanesque architecture. All three are clad in intricately carved black and white marble, and on bright summer days their brilliance can be blinding

Explore Christopher Columbus’s hometown as your Tour Director takes you through the winding alleyways of Genoa. You’ll see stately Renaissance homes scattered within the city’s Old Town, the palace from which dukes ruled over this port city, which was one of the most important in medieval Italy, and the Church of San Lorenzo, which once held the remains of John the Baptist. Try some pasta and pesto—pesto, a deliciously Italian combination of basil, garlic, and olive oil, was invented in this region, and Genoa was the port through which pasta from the Middle East first came into Italy.

To celebrate the 500th anniversary of the voyage of Genoa's most famous resident, Christopher Columbus, the city constructed an immense aquarium shaped like a ship setting sail. Recently a real-life boat was added to the space, doubling the aquarium's size. See jellyfish, crocodiles, eels, dolphins, sharks, and all manner of other Mediterranean and international sea creatures in this amazing aquarium, one of Europe's most popular.

Flowers, pedestrian boulevards, and decorative pavement make Barcelona a great walking city, and your Tour Director will show you where to stroll. See the Mercat de la Boquería, where the bright colors of fruits and vegetables, spices, fresh seafood and meat -- not to mention about a hundred different types of cheese -- vie for space in the market stalls. In the city center you'll see the Monument a Colom, a towering statue of Christopher Columbus. Gaze at the city stretched out before you, the mountains in the distance, and the Mediterranean Sea at your back. Then it's on to the best walk in the city, Las Ramblas, a mile-long pedestrian street that offers up the carnival of urban Barcelona. Have your palm read or browse through the strip's famous open-air shops. Enough walking for one day? Pull up a chair, order a café con leche, and watch the parade of street performers from your seat.

See brilliant Barcelona, a city of graceful Gothic churches, wrought-iron balconies and wide, grand avenues filled with outdoor cafés. Throughout the city, daringly innovative buildings sit side-by-side with the medieval past. A licensed, local guide will show you some of the high points of this architectural showcase. First stop: the pointy spires of the La Sagrada Familia (Church of the Holy Family), a half-finished church complex that became the obsession of Barcelona's famously eccentric architectural genius, Antoni Gaudí. Continue to the Spanish Village, where you'll view replicas of famous buildings and sights from every region of Spain. Then step back to the past with a journey up to Montjuïc (Hill of the Jews). See the fortress built atop an ancient Jewish cemetery. Site of numerous battles to control Barcelona, this hill was also the location of the 1992 Olympics.

It's like Dalí in 3-D. Gaudí's impressive outdoor park leads visitors through surreal twists, turns, ups, and downs as they navigate the sculptures, mosaics, and amazing views of Barcelona.

Tapas purportedly originated when bartenders set a small plate ("tapa") over patrons' glasses of sherry and wine to keep the flies out. The bartenders starting piling the plate with cold cuts, olives, or salad, and the bite-size snack was born. (We're unsure how they kept the flies out of the cold-cuts... maybe that's how the sandwich was invented?) Over time these working-class snacks have become more elaborate, with each region adding its own specialties and cooking techniques to create unique tastes and combinations.

Surrounded by Roman walls and topped by a beautiful towered basilica, Zaragoza will bring you back in time. Visit the popular pilgrimage destination of the Basilica of the Holy Virgin of Pilar, patron saint of all Spanish-speaking countries. The art inside includes works by Goya, who served his apprenticeship in this city.

Take a taste of Spain's cultural, political, and economic center with a tour led by a licensed local guide. See Madrid's mix of traditional and modern as you visit the Royal Palace, an 18th-century masterpiece. The enormous Baroque palace currently has more rooms (2,800) than any other European palace, but it was originally supposed to be four times as large. The palace is dripping with porcelain, jeweled clocks, amazing ceiling frescoes — the most magnificent, in the Throne Room, was done by the Venetian artist Tiepolo when he was in his seventies. Next take a look at the Neoclassical architecture of the Prado Museum and the Puerta de Alcala triumphal arch, built to honor Carlos III’s entry into Spain.

Originating from gypsy music and dance in Southern Spain, flamenco dancing has become a Spanish institution. Dancers use intricate footwork and elaborate arm gestures to convey the mood of the music, which can range from lamentation to celebration.

Long the spiritual capital of Spain, Toledo still captures the heart with its spectacular surround of ocher-colored mountains. El Greco created some of his greatest works here, including his most famous painting, "The Burial of Count Orgaz." You’ll also see the city's cathedral, St. Mary's Synagogue, and the Church of Santo Tomé.

Life in Madrid is centered around talking, toasting and tapas-eating. In a walk through this crowded and social city, your Tour Director will help you get to know the lay of the land. Visit the Museo del Prado, home of works by Spain's great masters, including Francisco Goya, Diego Velázquez, and El Greco. Then stroll over to the Puerta del Sol, the bustling city center. Next, you'll relax at the Plaza Mayor, a grand square where every sort of human drama has taken place-trails of faith, public burnings of heretics, royal marriages, the canonization of saints and countless balls and bullfights. End at the Plaza de España for a stop at an outdoor café.
