Start with the London Eye, a must-see and a must-see-from: on a clear day it offers spectacular views over the Thames and many of the landmarks of London, as far as the arch of the new Wembley Stadium and Windsor Castle. Right by the Eye in the old County Hall building are family attractions including the London Aquarium, London Dungeon, Shrek's Adventure and Namco Funscape.
Take a boat-trip from the Eye to maritime Greenwich or even the mighty defence system of the Thames Flood Barrier, taking you past many of London’s most famous sights. In Greenwich itself, explore the World Heritage site of the Royal Observatory, home to Greenwich Mean Time and a state-of-the-art planetarium, the National Maritime Museum, with interactive galleries about the history of seafaring, and the Cutty Sark, the world’s only surviving tea clipper, with a kids' trail and backpacks and lots of family activities. While you're in this part of London, take a scenic flight in one of the gondolas of the Emirates Air Line cable-car between Greenwich Peninsula and the Royal Docks.
Discover the other family attractions on the stretch of river between the London Eye and the iconic Tower Bridge, known as the South Bank (a great place for a stroll): the Golden Hinde, a replica of the 16th-century ship in which Sir Francis Drake circumnavigated the globe, the HMS Belfast, a World War II cruiser with decks to explore, and the reconstruction of Shakespeare’s Globe Theatre, with a hands-on exhibition and kids’ workshops.
But if you only have time to see one thing on the South Bank, make it the Tate Modern, a world-class modern art museum in an old power station, with a Family Zone full of books, quizzes and games. There’s normally a huge installation in the main hall that is worth the trip on its own, and multimedia handhelds for adults and kids help navigate the collection.
Explore the City, London’s Roman heart, easily accessed from the Tate Modern over the gleaming silver 'wobbly’ Millennium Bridge – which, happily, no longer wobbles. It takes you almost as far as St Paul’s Cathedral, designed by Sir Christopher Wren and famous for its Whispering Gallery, where you can hear someone whispering at the walls at the far side due to an acoustic weirdness.
From here it’s a short hop to the ever-expanding Museum of London to learn all about London’s history since prehistoric times, including the big nasties such as the Black Death and the Great Fire. Try to coincide your visit with one of the plentiful family-oriented events.
Have great days out in ‘Museumland’ in South Kensington, where ‘the big three’ of the Science Museum, Natural History Museum and Victoria & Albert Museum (V&A) rub shoulders. In fact, since all of them are gargantuan, you’ll need much more than a day to do justice to any single one. While not as immediately family-friendly as its neighbours, the V&A decorative-arts museum (which includes displays on fashion) has discovery areas for kids, family activities, and themed backpacks and trails. And one of London’s best-kept secrets is the V&A’s Museum of Childhood out in Bethnal Green to the east.
Don't miss other TaketheFamily favourites: the British Museum, the Tower of London, the Peter Pan/pirate-themed Diana Memorial Playground in Kensington Gardens, the London Transport Museum and nearby London Film Museum, the London Zoo in Regent’s Park, which has been wowing families more than ever since opening its Animal Adventure children's zoo, and the treetop adventure course Go Ape in Trent Park, Enfield.
Be West End boys and girls. London is red hot for family-friendly musicals and shows, especially the feline fantasia of the long-running Lion King. See Official London Theatre (officiallondontheatre.co.uk) for listings of both West End shows and performances at London’s wealth of smaller theatres (some of them specialist kids’ theatres).
Take kids 4–14 to role-play at KidZania, a 'city' where they can engage in more than 60 adventures based on real-life jobs – while you shop in the surrounding Westfield Mall (although ages up to 7 have to be accompanied by an adult).
Then there's the shopping - people come to London for this alone. Hamleys ain’t what it used to be, but your kids won’t care as they navigate its seven floors of toys, books and gadgets. More charming is Benjamin Pollock’s Toyshop in Covent Garden, or for an eye-opening glimpse of how the other half live, check out Harrods Toy Kingdom.
The award-winning walking tours firm Context Travel (contexttravel.com) can make London more accessible to those with kids with its family walks.
In addition to the sights above, we highly rate the following for different age groups:
Perfect for Toddlers
Battersea Park Children’s Zoo, a well-kept secret south of the river, with small animals (otters, owls, lemurs and so on), a farmyard and a superb playground.
Coram’s Fields, a wonderful Bloomsbury playground with a huge sandy play area for under-fives, an adventure area for older kids, an animal-petting enclosure, a summer paddling pool and a café.
Discover Children's Story Centre, an East London venue worth the schlep for its play spaces designed to encourage ages 0–11 years to make up stories with their families.
WWT Wetland Centre, a remarkable wildlife reserve not far from the heart of London, with a ‘bird airport’ and wildlife hides for spying on birds, water voles and more, plus an adventure area for kids 3–11 and an interactive discovery centre with water games.
Perfect for Primary-School Kids
DLR, a driverless overland train that kids love to sit at the front of and pretend to steer as it meanders between buildings, swooping up and down like a gentle rollercoaster. It’s a good way of visiting Docklands and Greenwich.
Foundling Museum, where you can learn about the Foundling Hospital, London’s first home for abandoned children, which stood on the site of Coram’s Fields next door (see above). Kids’ activity packs, audio-guides, drawing activities and events bring it to life.
Horniman Museum, an off-the-beaten-track attraction with a quirky collection (everything from torture instruments to puppets and giant model insects, some of which can be handled), an aquarium, family workshops, storytelling, night tours, music sessions, and arts and crafts. The gardens contain an animal enclosure and nature trail.
Perfect for Teens
Camden and Portobello markets, the first as tacky and grungey as it comes but an essential stop for those looking for alternative clothes, accessories and magnets, the second a perennially trendy haunt for aspiring fashionistas.
Churchill War Rooms, a double-whammy of culture where you can learn about Winston Churchill not only as a politician but as a father and son, and tour the secret bombproof bunkers where the War Cabinet hid out in air raids. Kids get free audioguides, trails and holiday activities and special events.
Thames Rockets, a high-speed boat ride along the Thames, taking in the sights to a soundtrack of funky tunes and the James Bond theme.
London Walks, a company offering a number of walks suitable for kids six and up, including costumed ghost walks, treasure hunts and occasional Thames archaeology outings looking for historical remnant on the river's beaches.
