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

See Trafalgar Square, often used for community gatherings and political demonstrations.

Visit the National Gallery, which contains an unrivaled collection of Western art spanning seven centuries, from the late 13th to the early 20th. The largest portion of the collection is devoted to the Italians, including works by da Vinci, Titian, Veronese, Tintoretto and Botticelli; but the collection also features works by the Spanish giants El Greco, Goya and Velázquez. The Flemish-Dutch school is represented by Brueghel, Jan van Eyck, Vermeer, Rubens and Rembrandt; and there is also an immense French impressionist and post-impressionist collection that includes works by Manet, Monet, Degas, Renoir and Cézanne.

Visit Piccadilly Circus, a shopping and entertainment area brightly lit with video displays and neon signs.

Covent Garden is a district in London, on the eastern fringes of the West End, between St Martin's Lane and Drury Lane. It is associated with the former fruit and vegetable market in the central square, now a popular shopping and tourist site, and with the Royal Opera House, which itself may be referred to as "Covent Garden". The district is divided by the main thoroughfare of Long Acre, north of which is given over to independent shops centered on Neal's Yard and Seven Dials, while the south contains the central square with its street performers and most of the historical buildings, theatres and entertainment facilities, including the London Transport Museum and the Theatre Royal, Drury Lane.

Leicester Square is perfectly situated in the heart of London's West End, with Trafalgar Square to the south, Piccadilly Circus to the west, Covent Garden to the east, and China Town to the north.

Nothing's more British than fish and chips-there are eight fish and chips shops ("chippies") for every McDonald's in the county. 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 King Charles III) 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. Please note Notre Dame Cathedral is currently closed due to fire damage.

View the Notre-Dame Cathedral. Work began in 1163 on a spot that had been a holy shrine since Roman times. Over the centuries, the cathedral has been the scene of some of France's most momentous occasions, including the coronation of Napoleon.

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 and the Place de la Concorde, where in the center you’ll find the Obelisk of Luxor, a gift from Egypt in 1836. 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) and the École Militaire (Napoleon's alma mater).

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.)

Take a walk past Rome's most beautiful and unusual Baroque fountains. At the foot of the Spanish Steps, elegant cafes 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.

View the Trevi Fountain, where it is traditional to toss a coin into the fountain to ensure a safe return to the Eternal City.

We will spend some time in the Piazza Navona area. Built on the foundations of Domitian's Circus, this magnificent square was designed by Borromini in 17th century. It is full of life and is highlighted by one of Rome's most spectacular fountains, the Four Rivers designed by Bernini. The square is often filled with local artists. The surrounding neighborhood is also one of the best places in Rome to get a tasty tartufo or gelato ice cream

The ultimate symbol of Ancient Rome, the Colosseum still dominates the modern city. Tour the amphitheatre with your local licensed guide. Built by the emperor Vespasian in A.D. 72, the structure held almost 50,000 spectators but was so well organized that the entire place could be emptied within 15 minutes. Inside, the spectacles varied from gladiator battles to immense naval contests to wild beast shows, in which thousands of exotic animals like giraffes and ostriches were popped into the stadium through trap doors and left to fight Roman hunters. See the system beneath the floor that operated the trap doors and housed the animals, then continue on to the relative calm of the Forum. Ancient Rome’s commercial, religious and political center, the Forum held markets, temples and the Senate House. Near the Rostra, or speaker’s platform, you can still see game boards scratched into the marble by bored politicians--anyone up for a game of tic tac toe?

Tour the ruins and excavations of the Roman Forum, which features the remains of magnificent temples, basilicas, and triumphal arches that once formed the heart of the Empire.

Visit St. Peter’s Basilica where from the outside, the church has four rows of columns that radiate out like welcoming arms; inside, the church seems enormous enough to embrace the entire world. The dome, partially designed by Michelangelo, rises 452 feet above the ground. Michelangelo’s mark is everywhere here, from the costumes worn by the Swiss Guards to his exquisite “Pietà” sculpture (the only sculpture he ever signed) to the amazing frescoes of the Sistine Chapel. Because he considered himself a sculptor and not a painter, Michelangelo hated working on these paintings, now considered masterpieces.
