Step outside your hotel for a stroll through 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, royal parks to street art. 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.

Located in an impressive domed building right in Trafalgar Square, the National Gallery houses a rich collection of over 2,000 works of art dating from the mid 13th century to 1900. Explore the beautiful marble hallways to see famous paintings by Van Eyck, Turner and Van Gogh.

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. Then head to the Île de la Cité, a small island in the Seine, to see Notre Dame Cathedral.

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. Your licensed local guide will elaborate on this, and other Parisian landmarks. See 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, where in the center you’ll find the Obelisk of Luxor, a gift from Egypt in 1836, and the Place Vendôme, a huge square surrounded by 17th-century buildings. 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).

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.

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. 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.)

Please note overnight trains from Paris to Florence and Rome are no longer operating. Overnight trains from Paris will now terminate in Milan, transfers by bus to Florence will be organized as a replacement service.

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.

Pope Gregory IX laid the first stone of the Lower Basilica the day after the canonization of St Francis, on July 17, 1228. Two years later the saint's body, that had been resting in the church of San Giorgio (the future church of St Claire's) was brought here in secret for fear of looting by tomb raiders and buried in the unfinished church. No date has been recorded concerning the start of works on the Upper Basilica, but it must have been after the abdication from the order of Brother Elia in 1239, who had hitherto directed the works on the Romanesque Lower Basilica. Both churches were consecrated by Pope Innocent IV in 1253.

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).

From the Bay of Naples the island of Capri is less than an hour away by boat. Weather permitting, you will take a boat to the Blue Grotto, where sunlight reflected from beneath the water bathes the cave in a silver-blue light.

Pompeii is a vast archaeological site located in southern Italy’s Campania region. Once a thriving and sophisticated Roman city, Pompeii was buried in meters of ash and pumice after the catastrophic eruption of Mount Vesuvius in 79 A.D. Near the coast of the Bay of Naples, the well-preserved site features excavated ruins that visitors can freely explore.

Prophet from the past. Explore the impressive ruins at Delphi, which the Greeks considered the center of the world. Within the depths of the Temple of Apollo, a priestess would inhale intoxicating vapors that used to rise from the earth and, thus inspired, deliver the prophecies of Apollo. Modern visitors might find more inspiration in the view from Mount Parnassus, over 8000 feet high.

Not just another crowded dusty city, Athens has developed from the birthplace of democracy to a bustling modern metropolis. With a local licensed guide, start your time travel at the ancient hot spots of the first Olympic site and the sprawling Acropolis, classical Athens’ religious and civic center. The awe-inspiring Parthenon -- a temple dedicated to Athens’ patron saint Athena -- is the obvious centerpiece, but take time to examine the building next door, where sculpted women hold up the roof with their heads, and the amazing view of modern Athens below. Jump back to the present in Syntagma Square, the center of the modern city, to see the Parliament building and the British-style changing of the guards ceremony. (There’s a rather un-British flair to it, however -- the Greek guards wear white skirts, head scarves, and shoes and knee bands adorned with pom-poms.) Continue to Omonia Square, Athens' other main meeting point, to relax by the splashing central fountain ringed with palm trees.

You’re never more than a few steps away from the past in Athens. Accompany your Tour Director to the Plaka, the historic district that borders the Acropolis. In its twisting narrow streets you’ll catch glimpses of an older city, from wrought-iron balconies bursting with geraniums to traditional Greek dancing in basement tavernas. Continue on to the Temple of Olympian Zeus, begun in the 6th century B.C. and finished in A.D. 132 by the emperor Hadrian. Its enormous columns provide a sense of the scale of the original temple. Nearby, the elaborate Hadrian’s Arch separated the ancient and imperial sections of the city.
