London has some of the best museums in the world, and the good news for parents is that most of them are completely free. The less good news? Not all of them are set up for a toddler who wants to touch absolutely everything.
After countless museum visits with my own under-5s — some triumphant, some involving a meltdown near the gift shop — here are the ten that genuinely work for small children. Every single one is free to enter, buggy-friendly, and has a decent loo situation (because that matters more than any Van Gogh when you are potty training).
The undisputed champion of toddler museum visits. The dinosaur gallery will blow their tiny minds, and the blue whale skeleton in Hintze Hall never gets old — we have been dozens of times and my three-year-old still gasps. For older children (7+), the Investigate Centre lets them handle real specimens (book online). Under-5s are better off sticking to the main galleries, which are more than enough.
The Garden gallery in the basement is purpose-built for 3 to 6 year olds, with water play, building blocks, and a mini construction site. It is free but timed — book a slot online as soon as they are released. Older toddlers love the space gallery, and the gift shop is surprisingly good for affordable science kits.
This Bethnal Green museum reopened in 2023 after a massive renovation, and it is now one of the best museum experiences in London for small children. Three immersive galleries — Play, Imagine, and Design — are entirely hands-on. Toddlers can build, dress up, play with puppets, and explore sensory installations. If you only visit one museum on this list, make it this one.
Another east London favourite (technically in Hoxton), this one is a hidden gem. The Rooms Through Time displays are fascinating for little ones — they can peer into living rooms from different centuries and spot how things have changed. The museum offers hands-on family activities and interactive elements throughout. The gardens are beautiful in summer.
This is the museum parents forget about, and that is exactly why it is brilliant. A stunning townhouse near Oxford Street with an armoury gallery that will captivate any child who has ever picked up a stick and pretended it was a sword. It is small enough that you can do the whole thing in under an hour, which is roughly the attention span of a three-year-old. The central courtyard restaurant is lovely.
More manageable than Tate Modern for small children. The galleries are wide and less crowded, so you can actually let them walk without fear of bumping into someone. The Clore Studios run free drop-in art workshops for families most weekends, and the kids genuinely make things rather than just colouring in. The building itself is grand and impressive — toddlers love the big echoing rooms.
You might not think Trafalgar Square is toddler territory, but the National Gallery has worked hard to make it family friendly. Pick up a free family trail at the information desk — they give kids something specific to look for in each room, which stops the "I'm bored" complaints. Toddlers love the big paintings of horses and battles. The Sunflowers room is always a hit.
A properly interesting museum about the human body, health, and science. The free galleries explore themes of health, medicine, and what it means to be human through changing exhibitions and displays. It is small, manageable, and very close to Euston station. Note: the original Medicine Man gallery closed in 2022, but the museum continues to run family-friendly exhibitions and events worth checking their website for before you visit.
A small, quirky museum in Rotherhithe about the Thames Tunnel — the world's first tunnel under a navigable river. It does not sound like toddler material, but they run family workshops and the underground Grand Entrance Hall is genuinely atmospheric. Entry is free for under-16s but adults pay around 10 pounds. It is small enough for a quick visit and sits right next to a lovely stretch of the Thames Path.
Down in Forest Hill, this is a south London treasure. The aquarium, the taxidermy collection (the overstuffed walrus is legendary), the music gallery where kids can play real instruments, and the gorgeous hillside gardens with animal enclosures and a nature trail. It is worth the journey and easy to spend a full morning here. One of the few museums on this list where you could happily spend three hours.
All of these museums and many more are listed in the Little London directory, where you can filter by age, area, and whether it works on a rainy day. Happy exploring.
