  • Museums in London: Explore the world-renowned British Museum. There, immerse yourself in Ancient Egypt as you view the red granite statue of Amenhotep III, the "Pond in a Garden" false fresco, and the famed Rosetta Stone. See the reconstructed Nereid Monument, the Mausoleum of Halicarnassus, and sketches by da Vinci. After visiting the stegosaurus and stopping by the earthquake simulator at the Natural History Museum, go to the Victoria and Albert Museum (V&A). Marvel at the Ceramic Staircase's beautifully painted ceiling, view hand-painted tilework, delicate embroideries, and illuminated manuscripts.
  • Landmarks in London: Take photos outside Buckingham Palace, experience panoramic city views from atop the London Eye, walk around the Shaftesbury Memorial Fountain at Piccadilly Circus, visit the Tower Bridge and hear Big Ben toll the hours. Then, spend the afternoon in Hyde Park horseback riding, strolling around the Rose Garden and listening to the debaters at Speakers' Corner.
  • Shopping in London: Browse the trendy boutiques along King's Road and explore London's famed department stores. For luxury goods, visit Sloane Street and Harrods in Knightsbridge.

Getting around London:

Pick up a Visitor Oyster Card and take the Tube. If you want to sightsee on the way to your next activity, hop on an iconic double-decker red bus. Rent a bicycle and use the bike lanes that run through Inner London. You can also hail one of the ubiquitous black taxis.
