London has a reputation for being expensive, but a family trip to the capital does not have to cost a fortune. In fact, some of London’s most famous museums, parks, galleries and sightseeing experiences can be enjoyed completely free.
Whether you are visiting with toddlers, teenagers or a mix of ages, there are plenty of affordable things to do in London with family. The secret is to combine free attractions with smart transport choices, picnics and a little advance planning.
Here are some of the best budget-friendly family activities in London.
1. Discover Dinosaurs at the Natural History Museum
For families with dinosaur fans, the Natural History Museum is an obvious place to start.
Its permanent galleries are free to explore, although booking a free admission ticket in advance is recommended. The museum is particularly popular with children because its collections cover dinosaurs, wildlife, oceans, volcanoes and the natural world.
Because there is enough to see for several hours, it can easily fill a large part of your day without adding much to your sightseeing budget.
Budget tip: Bring your own water and snacks rather than buying everything inside tourist areas.
2. Explore the Science Museum
Just a short walk from the Natural History Museum is another excellent free family attraction: the Science Museum.
General admission is free, and the museum is open daily. Its galleries explore subjects including space, engineering, technology and scientific discoveries.
Some special exhibitions and experiences cost extra, but families can enjoy plenty without paying for add-ons.
A great money-saving plan is to visit both the Natural History Museum and Science Museum on the same day because they are close together in South Kensington.
3. Visit the British Museum
Older children who enjoy history can spend hours exploring the British Museum.
Entry to the permanent collection is free, although advance booking is recommended when possible.
Instead of trying to see everything, make the visit more enjoyable for children by choosing a theme.
You could challenge the family to find ancient Egyptian objects, Greek sculptures or fascinating objects from different civilizations.
4. Have an Adventure at the Diana Memorial Playground
If your children would rather climb, run and play than walk around another museum, head to Kensington Gardens.
The Diana, Princess of Wales Memorial Playground is free to enter and is designed around imaginative play. Following a major renewal, the playground reopened in August 2026 with updated play areas and a new galleon among its features.
It is especially useful for families with younger children who need somewhere to burn off energy between sightseeing stops.
Pair the playground with a picnic in Kensington Gardens for a low-cost family afternoon.
5. Enjoy a Picnic in London’s Royal Parks
One of the simplest ways to save money in London is to replace a restaurant lunch with a picnic.
Hyde Park, Kensington Gardens, Greenwich Park, Regent’s Park and St James’s Park all provide plenty of outdoor space for a family break.
Children can run around while adults enjoy a quieter moment away from busy streets.
Pick up sandwiches, fruit and drinks from a supermarket before reaching the main tourist areas, where food generally tends to cost more.
6. See London From the Sky Garden
You do not necessarily have to buy an expensive observation-deck ticket to enjoy impressive views of London.
Entry to Sky Garden is free, although you normally need to reserve a free ticket. Its current booking information states that free tickets are released in advance, with availability naturally limited.
From the top, families can enjoy views across London’s skyline while exploring the indoor garden.
Book as early as possible, particularly during school holidays and weekends.
7. Explore Tate Modern
Art might not sound like the first choice for a family outing, but Tate Modern can be surprisingly child-friendly.
Entry to the main gallery collection is free, while certain temporary exhibitions require paid tickets.
The huge Turbine Hall itself can be fascinating for younger visitors, and Tate also highlights several free activities and experiences for visitors.
Afterwards, take a walk along the nearby Thames for more free sightseeing.
8. Walk Along the South Bank
Walking is one of the best ways to experience central London on a budget.
A family walk along the South Bank lets you enjoy views of famous landmarks without paying admission charges.
Depending on how far you walk, you can see the Thames, bridges, street performers and some of London’s most recognizable buildings.
Turn it into a game for younger children by asking them to spot landmarks, boats, statues or unusual buildings.
9. Watch the Changing of the Guard
Watching the Changing of the Guard can add a classic royal experience to your London trip without increasing your attraction budget.
The ceremony at Buckingham Palace is free to watch and does not require an admission ticket, although the schedule can change because of ceremonial or operational requirements.
Crowds can become large, so arriving early is particularly useful when visiting with children.
Always check the current schedule before travelling specifically for the ceremony.
10. Explore London’s Markets Without Overspending
London’s markets can be attractions in themselves.
Walking through places such as Borough Market, Camden Market or Greenwich Market costs nothing. Families can explore the stalls, enjoy the atmosphere and share one or two snacks instead of purchasing a full meal for everyone.
Give older children a small spending allowance and turn the visit into a challenge to find the most interesting snack or souvenir within their budget.
11. Take a Family Bus Ride Instead of a Sightseeing Bus
Open-top sightseeing buses are convenient, but London’s regular buses can provide a far cheaper alternative.
Choose a route through central London and sit upstairs for views of the streets and landmarks.
Families travelling with young children can save even more because Transport for London states that children under 11 can travel free on buses and trams, while accompanied under-11s can also travel free on several other TfL services. Conditions apply, so check TfL’s current rules before travelling.
Children aged 11–15 may also qualify for discounted travel depending on the ticket or Oyster arrangement used.
12. Create Your Own London Treasure Hunt
One of the cheapest family activities requires nothing more than a phone camera and a list.
Create a treasure hunt that asks your children to find things such as:
- A red London bus
- A black cab
- Big Ben
- A royal guard
- A London Underground sign
- A bridge over the Thames
- A traditional red telephone box
- A famous statue
Give points for every item photographed.
It turns ordinary sightseeing into a game and works particularly well when younger children are getting tired of walking.
How to Visit London With Family on a Budget
Saving money in London is often less about finding one cheap attraction and more about planning each day efficiently.
Group attractions by area so you are not constantly paying to travel across the city. South Kensington, for example, is perfect for combining the Natural History Museum, Science Museum and Kensington Gardens.
Use free attractions as the foundation of your itinerary and choose only one or two paid experiences that your family genuinely wants to see.
Carrying refillable water bottles, eating supermarket breakfasts or lunches and using public transport rather than taxis can also make a noticeable difference over several days.
