Da Vinci's Codes

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. Look up at the great stone buttresses, grotesque gargoyles, and massive stained-glass windows.

Visit one of the original college towns. Since the Sorbonne’s founding in the 1100s, the Left Bank has attracted not only intellectuals but also the cafés, bookstores, and cinemas that tend to accompany them. It’s also attracted its fair share of famous residents – a plaque marks one of Hemingway’s apartments on rue du Cardinal-Lemoine, and the imposing neoclassical Panthéon holds the tombs of Voltaire, Rousseau, Victor Hugo, and Marie Curie.

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. 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.)

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 and must be booked 99 days prior to departure.)

You're so close, why not continue to London? Take the Eurostar under the English Channel. Faster than you can say...anything, in French, you'll whiz through a tunnel and arrive in London.

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.

See how the Queen relaxes on this guided tour of the royal weekend estate, originally built as a fortress in the 11th century under William the Conqueror. Tiptoe through the tulips (and other flowers) in the East Terrace Gardens, marvel at the Gothic St. George's Chapel, or peek into the rooms of Queen Mary's doll house with its gallery of pint-size perfect furniture. Get decorating tips for your own country estate (or dorm room, as it may be).

Edinburgh Castle, the historical and emotional heart of the city, is just one of the many sights you will see on this tour, led by a licensed professional guide. Make your way along the Royal Mile, the main thoroughfare of the 16th and 17th centuries. (It's actually one mile and 107 yards long--from Edinburgh Castle to the Palace of Holyrood House). As you make your way along cobbled streets, you'll see a handful of the several thousand buildings officially protected in Edinburgh because of their architectural or historic importance. The 200-foot spire of the Sir Walter Scott monument soars above the East Princes Street Gardens. Grand figures from Scottish history adorn its heights, make sure you also look down -- the figure below the marble statue is Scott's favorite dog, Maida.

If you think fairies are cute little twinkly things, think again. Take in the Scottish folklore show and learn about the kelpies, banshees, and selkies that inhabit this harsh land.
