Yes — you can fill a whole family day in London and spend nothing but the fare. The capital’s best free things to do are not consolation prizes: the national museums are free, the Changing of the Guard is free, the parks, the river walks, the markets and the skyline views are free. What follows is a real morning-to-evening plan, in the order that works, with the honest bit nobody else prints — what a “free” day actually costs once you have travelled in.
The short version
- A full day for £0 is genuinely doable. Entry to every activity below is free; the only real cost is travel.
- Best free fixtures: the Changing of the Guard, the South Bank, a royal-park picnic, a free skyline view, a London market, and the walk under the Thames at Greenwich.
- The catch is the fare. Under-11s travel free on Transport for London with a paying adult, and one adult’s contactless travel is capped at a daily maximum.
- It works in the rain. Swap the outdoor stops for a free national museum and the day still costs nothing.
- It works step-free. Most of the plan suits a buggy or a wheelchair; the accessible-day section flags the lifts and level routes.
A free family day out in London, hour by hour
The single most useful thing we can give you is not a list of forty attractions but an order to do six of them in. This plan threads together the free fixtures that sit close enough to walk between, starts with the one thing that runs to a timetable, and ends by the river. Treat the times as a guide, not a schedule.
The logic behind the order: the Changing of the Guard is the only fixture that runs to a clock, so it anchors the morning. From the palace you are a short walk from St James’s Park for an early picnic, then the river. The afternoon viewpoint and the market are interchangeable depending on where you have ended up, and Greenwich makes a fitting last act because the walk under the Thames is the kind of thing children remember.
The free things to do in London are not the budget option. They are, very often, the best things.
Watch the Changing of the Guard
The Changing of the Guard at Buckingham Palace is free, needs no ticket, and is the one piece of pageantry that justifies an early start. In 2026 it is scheduled on Mondays, Wednesdays and Fridays, with a Sunday parade as well; the main handover is around 11am (a little earlier, about 10.45, on Sundays). The schedule is provisional and confirmed roughly six weeks ahead, and it can be cancelled at short notice in heavy rain or for a state event, so it is worth a check the night before on the Household Division’s site.
For a view with smaller children, skip the palace railings — they fill early — and stand instead on the steps of the Victoria Memorial, or along The Mall to watch the troops and the band march past, which is the better spectacle anyway. Arrive by about 10.15 in summer.
Good to know
The guards you will see are working soldiers, not actors — the regiments of the Household Division on a genuine duty handover, in a ceremony that has run in some form for centuries. It is free precisely because it is real.
Wander the South Bank and watch the buskers
The stretch of the Thames between Westminster and Tower Bridge is the best free walk in London, and the buskers are part of the deal. Licensed performers play at marked pitches along the Queen’s Walk — near the Southbank Centre, by Jubilee Gardens and around the Golden Jubilee bridges — and watching them costs nothing, though a coin in the hat is good manners if you stop for a whole set.
Tuck under the Queen Elizabeth Hall to find the Undercroft, the graffiti-covered concrete bay that has been London’s skateboarding heart since the early 1970s and is widely called the birthplace of British skate culture. It is free to watch the skaters and BMXers, and children are mesmerised by it. Further along, the secondhand book market under Waterloo Bridge is free to browse and a fine place to lose twenty minutes.
A free skyline view, no Shard ticket required
You do not need to pay for a viewing platform to see London from above. The Sky Garden, the glasshouse on top of the “Walkie-Talkie” at 20 Fenchurch Street, is free — but you must book a timed ticket in advance. New tickets are released every Monday morning for visits about three weeks ahead and the sunset slots go quickly; walk-up spaces are sometimes available on quiet weekday mornings, and adults need photo ID for the airport-style security.
If the Sky Garden is fully booked, the free alternatives are better for a family anyway: climb Greenwich Park to the Royal Observatory railings, or Parliament Hill on Hampstead Heath, for a long view over the city with room for children to run and no booking at all.
Picnic in a royal park
The eight Royal Parks are free, beautifully kept, and the cheapest lunch in London is the one you bring. St James’s Park, between the palace and Horse Guards, has pelicans and the best view of the skyline reflected in its lake; Hyde Park and neighbouring Kensington Gardens give you the Diana Memorial Playground with its wooden pirate ship and the Peter Pan statue; Greenwich Park has deer, wide hills and a playground.
The thrifty bit
A packed lunch eaten on the grass is not a compromise here — it is the nicer option. A flask, a rug and a bag of sandwiches turns a free park into the centrepiece of the day, and saves the £30-odd a family of four will otherwise drop on a mediocre café. Refill water bottles at the free public fountains the Royal Parks now dot through the grounds.
Browse a London market
London’s markets are free to walk through, and the good ones are a sensory day out in themselves. You can browse without spending a penny, though resisting the food stalls takes resolve. Check the day before you go — most markets do not run daily:
| Market | Best for | When |
|---|---|---|
| Borough Market | Food stalls, free samples, river-side setting | Most days; liveliest Fri and Sat |
| Columbia Road Flower Market | Flowers, colour, East End atmosphere | Sundays, roughly 8am–3pm |
| Camden Market | Teenagers, street food, canal-side wandering | Daily, from about 10am |
| Greenwich Market | Crafts, ties in with the Greenwich plan below | Tuesday to Sunday |
Walk under the Thames at Greenwich
The Greenwich foot tunnel is free, open around the clock, and walking under a river is a small adventure children do not forget. Opened in 1902, it runs from Greenwich beneath the Thames to the Isle of Dogs, with lifts at both ends. Surface on the north bank at Island Gardens for the “Canaletto view” — the painter’s famous prospect of the Old Royal Naval College across the water — then walk back.
While you are in Greenwich, stand astride the Prime Meridian line in the courtyard of the Royal Observatory (the line itself is outside the paid galleries and free to reach), where east meets west at zero degrees longitude. It is the rare free activity that is also genuinely educational, which is a useful thing to have in your back pocket on a Sunday.
Free festivals and events through the year
Time a London visit to a free festival and the city throws the entertainment in for nothing. The headline fixtures in 2026:
- Notting Hill Carnival — Europe’s largest street festival, free to attend, over the August bank-holiday weekend (29–31 August 2026). Spectacular, and very crowded; the Sunday “Children’s Day” is the gentler option for families.
- Diwali in Trafalgar Square — a free festival of light each autumn with dance, music and a children’s zone.
- St George’s Day in Trafalgar Square — a free celebration around 23 April with food and entertainment.
- The Lord Mayor’s Show — a free procession of floats and bands through the City each November.
Trafalgar Square is the city’s free events stage, hosting open-air screenings, cultural celebrations and seasonal markets through the year; it is always worth checking what is on the square for the date you are going. If you are planning around a long weekend, our guide to August bank holiday family days out sets the dates and ideas across the country.
A note on the free museums
It is true: the permanent collections of London’s great national museums are free, with no ticket needed. The British Museum, the National Gallery, the Natural History and Science Museums, the V&A, Tate Modern and Tate Britain all let you in for nothing. The honest caveat is that their blockbuster temporary exhibitions charge separately, typically £12–25 a head, and the British Museum asks you to book a free timed slot at busy times. The free permanent galleries, though, are among the finest in the world and a reliable wet-weather rescue.
Because the museums and galleries are the heart of a separate guide, we have kept them brief here. For the full directory of free attractions, see our companion guide to free places to visit in London.
The honest bit: what a free day really costs
“Free” is true for the activities and not quite true for the day, because you still have to get there. This is the part the listicles leave out, and it is the part that decides whether a free day actually saves you money.
The good news for families is that children under 11 travel free on the Tube, buses and most of the rail network in London when they are with a fare-paying adult, so a family of four often pays only two adult fares. Each adult’s contactless or Oyster travel is capped at a daily maximum, so once you have hit the cap, extra journeys cost nothing. Tap the same card all day; the cap does the arithmetic for you. Walking between the clustered central stops, as the plan above does, keeps even those fares down. If a paid treat does tempt you on another day, it is worth weighing whether a year’s pass earns its keep — we have run the numbers on whether National Trust membership is value for money.
A step-free, accessible free day
Most of this plan works for a buggy or a wheelchair, which is not something every “free London” guide bothers to say. The Changing of the Guard is watched from open pavement and the Victoria Memorial steps have level approaches nearby; the South Bank’s Queen’s Walk is flat and wide; the Royal Parks have paved paths and accessible playgrounds. The Greenwich foot tunnel has lifts at both ends, and the national museums are fully step-free with lifts throughout.
The honest exceptions: lifts in older tunnels and stations occasionally close for maintenance, so if step-free is essential, check Transport for London’s live access status the morning you travel and plan the level interchange stations into your route. A handful of viewpoints, such as Parliament Hill, involve a climb.
The free activities people forget
A few of London’s best free things to do are activities rather than places, and they slip off most lists. Follow the Scenes in the Square trail through Leicester Square, hunting the bronze film statues from Paddington to Mary Poppins with the free audio guide on your phone. Watch a debate from the public gallery of the Houses of Parliament, which is free to UK residents. Take a self-guided walk of the City’s hidden churchyards and alleys, or ride a Routemaster bus route end to end from the top deck. None of these costs more than the fare, and all of them give children something to do rather than something to look at.
Free things to do when it rains or after dark
A wet forecast does not cancel a free day in London — it moves it indoors. Swap the river walk and the viewpoint for one of the free national museums, which can absorb a whole afternoon. The covered halves of Camden and Borough markets stay dry, and a red double-decker bus (a normal fare, not a tour) makes a fine cheap sightseeing tour from the top deck when the weather is filthy.
In the evening, much of the best of free London is the city lit up: the South Bank at dusk, the skyline from Waterloo Bridge, the Christmas lights on Oxford and Regent Streets from November, and the buskers who play on into the night. Window-shopping the festive displays costs nothing and feels like an occasion.
Frequently asked questions
What can you do in London for free?
Plenty: visit the national museums and galleries, watch the Changing of the Guard, walk the South Bank, picnic in the Royal Parks, browse the markets, take in a free skyline view from the Sky Garden, walk under the Thames at Greenwich, and time a visit to a free festival such as Notting Hill Carnival or Diwali in Trafalgar Square. A whole family day can cost nothing but the fare.
Are London’s museums really free?
Yes — the permanent collections of the national museums (the British Museum, National Gallery, Natural History Museum, Science Museum, V&A, Tate Modern and Tate Britain) are free, with no ticket required, although some ask you to book a free timed slot at peak times. Their special temporary exhibitions are ticketed separately, usually £12–25.
Is the Changing of the Guard free, and what days is it on?
It is free and needs no ticket. In 2026 it is scheduled on Mondays, Wednesdays and Fridays plus a Sunday parade, usually around 11am. The schedule is provisional, confirmed about six weeks ahead, and can be cancelled in bad weather, so check before you set off.
How do you get free tickets for the Sky Garden?
Book online at the Sky Garden’s own site. Free timed tickets are released every Monday morning for visits about three weeks ahead and go quickly, especially the sunset slots. A limited number of walk-up spaces are sometimes available on quieter weekday mornings; bring photo ID for security.
What’s the cheapest way to get around London for a day out?
Pay with one contactless card or Oyster and let the daily cap limit your spend — once you reach the cap, further travel that day is free. Children under 11 travel free with a fare-paying adult. Walking between the central, clustered sights keeps fares lower still.
What can you do in London for free with young children?
The Royal Parks and their playgrounds (the Diana Memorial Playground’s pirate ship is a favourite), the free museums with their hands-on galleries, the South Bank buskers, and the walk under the Thames at Greenwich all suit small children and most work with a buggy.
