London is the UK’s capital and one of the best big cities in the world to visit with kids, largely because its blockbuster museums are free — you can walk out the moment attention spans collapse without feeling you’ve wasted a ticket.
Why Go
No other city packs this many world-class, genuinely child-friendly attractions into one transport network — and the headline museums cost nothing, so a family week here can be far cheaper than its reputation suggests. Layer on royal pageantry, river boats, and some of Europe’s best playgrounds, and London earns its place as the natural first UK stop.
Key Sights
Natural History Museum — the dinosaur gallery and the earthquake simulator are the reliable hits; arrive at opening and use the Exhibition Road side entrance.
Tower of London — the big-ticket attraction most families agree is worth the money: real armour, ravens, and the Crown Jewels on a moving walkway that keeps the line flowing.
Science Museum — next door to the NHM, with the hands-on Wonderlab gallery (small charge) that absorbs kids for hours on a rainy day.
Buckingham Palace and the Changing of the Guard — free; check the ceremony calendar and stand near the Victoria Memorial for the best kid-height views.
London Eye — expensive but memorable; book online for the first rotations of the day.
Things To Do
- Walk the South Bank from the London Eye to Borough Market — street performers, skate parks, and river views make it the best free afternoon in town.
- Let kids captain a boat on the Diana Memorial Playground’s pirate ship in Kensington Gardens.
- Ride the top-front seats of a double-decker bus as budget sightseeing.
- Take a Thames river bus (Uber Boat) between Westminster and Greenwich, then stand on the Meridian Line.
- Catch a family-friendly show — the West End’s matinees and the open-air theatre in Regent’s Park both work well from about age 6.

Travel Route
Base yourself in South Kensington (museums on the doorstep) or King’s Cross (value and rail links), then work in zones: museums one day, Tower and river the next, palace and parks the third. Children under 11 travel free on the Tube and buses with a fare-paying adult; contactless caps your daily spend automatically. Save Greenwich for a fine day and arrive by river boat.
