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.)

Commence your city walk at Alexanderplatz, known to locals as simply "Alex". This public square is dominated by the impressive TV Tower, built by the former socialist East German government in the 1960's as a showcase to the West. Today the tower shapes the skyline of the city. See the World Time Clock, which shows the time for various cities around the world, and the Red City Hall, once again Berlin's administrative center since reunification. Take a stroll down the boulevard "Unter den Linden" to Bebelplatz, the site of the Nazi book burnings and see the memorial to commemorate the event. Walk through the Hackesche Hoefe - a courtyard complex built in the "Judenstil" or Art Nouveau style. Pass through the medieval Nikolai Quarter, famous for its vibrant restaurants and cafes which was destroyed by Allied bombing in WWII, but has since been rebuilt. Then view Museum Island, home to a complex of 5 major museums and a UNESCO World Heritage Site. A city with a rich and complex past, your Berlin City Walk will be one of the most memorable parts of your trip!

Visit the museum that documents the history and significance of the most famous crossing point between East and West Berlin during the Cold War.

Join a professional, licensed tour guide as you discover one of the most historical cities in Germany. Although nothing remains of the mortar and cement-block barrier between East and West Berlin, the Berlin Wall (built in 1961; destroyed in 1989) is still a main “site” in Berlin. View the well-known Brandenburg Gate, once a main gate hidden behind a 10-foot barrier and now known for celebratory dancing on its flat top during the reunification. Travel to the Checkpoint Charlie Museum, the most famous border crossing point. Checkpoint Charlie, once a wooden guard hut, was the most (in)famous border-crossing point between East and West Berlin from 1961 to 1989. All that remains of the checkpoint itself is a skeletal watchtower and a memorial of attempted escapees. Follow your guide as they lead you through the museum’s accounts of the most ingenious of these escape attempts— even a few by hot air balloon.
