Let’s be honest — entertaining the kids in a big city like London can sometimes feel like you’re just throwing money at snacks, tickets and random souvenirs. But guess what? You don’t have to spend a fortune (or anything at all!) to have a brilliant family day out in the capital.
There are loads of free things to do in London with kids, and some of them are surprisingly awesome. Whether it’s the school holidays, a rainy Sunday, or just a spur-of-the-moment adventure, there’s fun to be had all across the city — and we’re not talking about standing around watching pigeons in Trafalgar Square.
So, if you’re after a mix of fun, learning, play and imagination without breaking the bank, this list is for you.
London is packed full of exciting stuff for kids of all ages, and a lot of it won’t cost you a penny. The trick? Knowing where to look. From immersive museums to wild outdoor spaces, this city’s got something for every curious little explorer.
Whether you’re chasing dinosaurs, dodging the rain, or just looking for some quality time together, here are ten genuinely brilliant free things to do in London with kids and all the family.
No list of free attractions in London for families is complete without this gem. The Natural History Museum is totally free and full of wide-eyed wonder for kids – especially those obsessed with dinosaurs, space, or volcanoes. The animatronic T-Rex never fails to get jaws dropping.
And if you’re looking for free indoor activities in London on a rainy day, this is a go-to that’s both educational and epic.
Just next door is another family favourite. The Science Museum’s interactive galleries and the Wonderlab (note: Wonderlab has a charge, but the rest is free!) make this a massive hit. Budding inventors and rocket scientists will be in heaven. Plus, it’s a good one for keeping all ages engaged – even teens.
It’s totally free, it’s full of ceremony and marching band vibes, and it’s uniquely British. Kids love the costumes, music and the horses — and it makes for an excellent photo op too. It’s one of those free places to visit in London with family that’s a proper memory-maker.
Inspired by Peter Pan, this playground in Kensington Gardens is seriously magical. There’s a huge pirate ship, teepees, and loads of space to run, climb and pretend. It’s completely free and designed to let little imaginations run wild.
Covent Garden is a buzzing spot where you’ll often find world-class street performers – jugglers, magicians, acrobats and even living statues. It’s a great stop-off during a walk around the West End, and one of those free attractions in London for families that offers something different every time.
Not quite what you’d expect in inner London, Hackney City Farm is a brilliant chance for kids to meet goats, pigs and chickens up close. It’s totally free to enter and has a lovely, relaxed vibe that’s ideal for toddlers and younger children. Pack a lunch and make a day of it. When it comes to free things to do in London with kids, this really is a great option.
Need some fresh air and a killer view? Climb to the top of Primrose Hill and look out over the whole city. It’s a fantastic place for a sunset family picnic (yep, even with picky eaters) and space to play. Best of all, it’s completely free and often far less busy than other parks.
The Southbank Centre is full of surprises. From pop-up installations to family-friendly events and workshops, there’s often something going on – and many of the activities are free. It’s a fab pick when you’re looking for free indoor activities in London that are fun but a bit artsy.
On a warm day, kids can run wild in the interactive fountains at Granary Square, just behind King’s Cross. Bring a towel and spare socks – you’ll probably need them! While you’re there, enjoy the buzzing area packed with seating, street food and space to chill.
If your kids are into colour and cool stuff, take them on a self-guided street art adventure in East London. Shoreditch, Hoxton and Brick Lane are packed with bright, weird and wonderful graffiti and murals. It’s a walking gallery with zero ticket price.
You can even turn it into a game — spot the most unusual design, or find every colour of the rainbow. It’s creative, active and one of the most fun free things to do in London with kids that also works for adults.
