Free museums are one of London's great gifts to parents of small children. On a rainy Tuesday or a packed half-term Saturday, these places are a lifeline: warm, stimulating, and genuinely kind to families with buggies and toddlers who need room to move. Here are six of the best, all free to enter, and all worth the journey with an under 5.
A note before you go: even free museums benefit from booking in advance during busy periods. Check each venue's website for timed entry requirements, particularly during school holidays.
One of the most spectacular buildings in London, and a genuinely wonderful experience for small children even before you get to the dinosaurs. The central hall alone, with its soaring arches and the blue whale suspended overhead, is worth the journey. The dinosaur gallery is a perennial favourite, and the mammals room gives children a sense of scale that no picture book can replicate.
Buggies are welcome throughout most of the museum. Arrive early to avoid the peak crowds, particularly at weekends and during school holidays.
The Garden gallery, designed specifically for children aged three to six, is one of the best indoor play spaces in London. Water play, construction activities, and cause-and-effect experiments keep young children absorbed for well over an hour. The rest of the museum rewards curious older toddlers too, with interactive exhibits across multiple floors.
Timed entry for the Garden gallery is required and books up quickly at weekends, so plan ahead. The museum has good buggy storage and accessible facilities throughout.
Housed in a converted Georgian warehouse on the Isle of Dogs, the Museum of London Docklands tells the story of the river and the port that shaped the city. For families, the Mudlarks gallery is the draw: a hands-on exploration space designed for children where they can dig, sort, and discover. It is one of the least crowded of the major free museums, which makes it genuinely relaxing to visit with a buggy or a wandering toddler.
Well served by the DLR, and close to Canary Wharf with plenty of eating options nearby.
Redesigned and relaunched as the Young V&A in 2023, this is among the best options for under 5s in London. Three hands-on galleries cover Imagine, Play, and Design, with everything built to be touched, climbed, and explored. The Play gallery in particular is exceptional: a space designed entirely around how children aged 0-12 engage with the world through play. Toddlers can spend a full visit here without seeing the same thing twice.
The museum is directly outside Bethnal Green tube station, is fully step-free, and has excellent changing facilities. It draws fewer crowds than the South Kensington museums and the atmosphere is noticeably relaxed.
The Horniman is a south London gem that many central London families overlook. The museum building itself is unusual and beautiful, and inside you will find a natural history collection, a music gallery, and a small aquarium (the aquarium has an entry charge). Outside, the free gardens include a small animal walk with farmyard animals that young children love. The combination of museum and outdoor space makes it an excellent half-day destination.
Easily reached by overground train to Forest Hill. The garden cafe has plenty of outdoor seating when the weather allows.
The British Museum is vast, and with very young children it can feel overwhelming if you try to see too much. The trick is to pick one or two highlights and not be ambitious. For under 5s, the Egyptian mummies tend to provoke strong reactions, and the Great Court itself, with its glass-and-steel roof, is an impressive space to wander. The museum runs family activity trails which give children a specific task to focus on as they move through the galleries.
Book a timed entry slot in advance. The museum gets very busy, particularly at weekends and during the summer holidays. Buggy access is good throughout the main floors.
A few things that make a real difference with young children at museums. Go in the morning when children are freshest. Pack your own snacks, because museum cafes are expensive and the queues can be long. And set a realistic time limit: two hours is usually a better visit than four hours that ends badly.
All of these museums are listed in the Little London directory, where you can filter by area, age group, and whether booking is required.
