Free Things to Do in London with Kids
London has more world-class free attractions than almost any other city. These are the best free London family activities that cost nothing to enter.
Natural History Museum
The Natural History Museum is one of the best free things to do in London with kids and consistently tops family activity lists. The dinosaur exhibits are genuinely spectacular — the blue whale skeleton in the main hall alone is worth the visit. Children can borrow activity backpacks with trail challenges suited to their age. Free entry every day with no booking required for the permanent collection.
Science Museum
Right next door to the Natural History Museum, the Science Museum is another outstanding free London activity for children. Interactive exhibits cover space exploration, engineering, flight, and technology across seven floors. The Wonderlab interactive science gallery is paid but worth booking for children aged 7 and over. The rest of the museum is completely free.
British Museum
The British Museum welcomes over 6 million visitors annually and its permanent collection is completely free. For families, the Egyptian mummies, the Rosetta Stone, and the Sutton Hoo helmet are highlights that genuinely capture children’s imaginations. The museum runs family trails and activity sheets available from the information desks. Best visited on weekday mornings to avoid weekend crowds.
Changing of the Guard, Buckingham Palace
One of London’s most iconic free family activities, the Changing of the Guard takes place at Buckingham Palace and is completely free to watch from the street. The ceremony features military music, ceremonial uniforms, and impressive formations that children find genuinely exciting. Arrive at least 45 minutes early for a good viewing position, especially during peak season.
Hyde Park and Diana Memorial Playground
Hyde Park is one of the best free outdoor family activities in London. The Diana Memorial Playground in the northwest corner is specifically designed for children aged 12 and under, with a large wooden pirate ship as its centrepiece. The park also has the Serpentine Lake for paddleboats, open-air concerts in summer, and wide open spaces for picnics and ball games.
Best Paid Attractions for Kids in London

London Eye
A 30-minute rotation on the London Eye gives children one of the most memorable views of the city — Big Ben, the Thames, and the London skyline stretching in every direction. Book fast-track tickets online in advance to skip queues that can exceed an hour during peak season. The Eye is particularly special at sunset when the light on the Thames is spectacular.
Tower of London
The Tower of London is one of the most captivating London attractions for children. The Crown Jewels, the famous Beefeater Yeoman Warder tours with their dramatic storytelling, medieval armour, and the ravens all genuinely capture children’s imaginations.

Located on the South Bank next to the London Eye, SEA LIFE London Aquarium is one of the most popular paid activities in London for kids. Home to over 400 species including sharks, rays, seahorses, and penguins, it offers a walkthrough tunnel beneath a shark tank that younger children find both thrilling and unforgettable. The penguin feeding sessions are particularly popular — check the schedule on arrival.
Hop-On Hop-Off Bus Tour
A hop-on hop-off bus tour is one of the most practical things to do in London with young children. It covers all the major landmarks — Big Ben, Buckingham Palace, Tower Bridge, St Paul’s — with multilingual audio commentary, and lets you get on and off at your own pace. For tired families with young children, staying on the bus for the full loop and watching the city pass by is genuinely enjoyable. 24 and 48 hour passes available.

Each visitor gets a personalised spy profile at the end based on their skills across the missions.
Oxygen Trampoline Park at The O2
Oxygen at The O2 is one of the best indoor activities for kids in London who need to burn energy. Alongside interconnected trampolines, there are ninja-style obstacle courses, climbing walls, and high-energy activity zones. The O2 location also makes it easy to combine with food at the surrounding restaurants for a full family day out in Greenwich.
West End Family Shows
A West End show is one of the most memorable things to do in London with children of all ages. The Lion King, Matilda the Musical, Disney’s Frozen, and Back to the Future the Musical are all consistently excellent for families. Matinee performances are less expensive than evening shows and better suited to younger children. Check the TKTS booth in Leicester Square for same-day discounted tickets.
Hamleys Toy Store, Oxford Street
Hamleys is the world’s most famous toy store and a genuine free London attraction for kids — entry is free even if you do not buy anything.

The Gorilla Kingdom and Land of the Lions are particular highlights for families with children of all ages.
Hampton Court Palace and Maze
Hampton Court Palace is one of the best family day trips from London, reachable in 35 minutes from Waterloo. The famous hedge maze is a highlight for children, and families can borrow dress-up costumes to explore the Tudor kitchens, dining halls, and royal apartments.
