Fortunately for travelers, many of London's popular attractions can be found in clusters. Children may recognize several famous landmarks in the section of the city known as Westminster---Trafalgar Square, Buckingham Palace, St. James Park, Westminster Abbey and Parliament (housing the clock known as Big Ben)---situated near each other north of the River Thames (pronounced "Temz"). Across the river is the London Eye, which offers a bird's eye view of the city's famous attractions.
A boat ride down the Thames can be a fun way for kids to explore the city quickly. Ranging from 30 minutes to three hours, cruises offer children quick glimpses and some background about the city's other famous landmarks such as County Hall, the London Aquarium, Royal Festival Hall, St. Paul's Cathedral, the Millennium Footbridge, Shakespeare's Globe Theatre, Tower Bridge, the Tower of London and Greenwich.
The British Museum is the most popular museum in London. Children will be awed by the expansive great court and ancient artifacts from Egyptian, Greek and other ancient civilizations. Admission is free, although visitors are encouraged to make a donation.
Hop on "the tube" (London's underground train) to South Kensington to visit the Science Museum, which offers more interactive exhibits for younger children. The Natural History Museum, housing over 70 million items in its collections of dinosaur bones, plants, bugs, animals and rocks/minerals, and the Victoria & Albert Museum, featuring art and design exhibits, are also free and just a short walk from the Science Museum.
Older children may also get a kick out of visiting the London Dungeon, highlighting England's darker history, or Madame Tussaud's wax museum, to get a photo with a favorite celebrity or historical figure.
Stop in one of the local shops, or a Pret A Manger deli for a sandwich "take away," and picnic in one of London's tranquil parks. Kids will enjoy a break from the sightseeing and the opportunity to watch other children playing football (known in the U.S. as "soccer"). The London Zoo is located in Regent's Park. Other popular green spaces include Hyde Park, St. James Park and Greenwich.
London is home to several world-class theatrical productions. However, not all of them are suitable for children; check out reviews ahead of time in London's "Time Out" publication. For other age-appropriate shows, visit the Neverland Pavilion, Little Angel Puppet Theatre or Peacock Theatre.
