The best free things to do in London in 2026 are the views from the Sky Garden, the Changing of the Guard at Buckingham Palace, and the free national museums — the British Museum, National Gallery and Natural History Museum. Walk the South Bank to Tate Modern, then climb Parliament Hill or Greenwich Park for the skyline.
London is one of the best cities in the world for free sightseeing: the national museums cost nothing to enter, the Royal Parks are open daily, and the river walks pass most of the famous landmarks. The main cost is getting around — tap in with a contactless card on the Tube and buses, and daily spending is capped automatically.

1. Sky Garden — City of London
London's highest public garden, with free 360° views from the top of the 'Walkie-Talkie'.
Best for Couples · First-timers · Budget
The Sky Garden fills the top three floors of 20 Fenchurch Street with planted terraces under a glass dome and an open-air balcony. The views across the Thames to the Shard, Tower Bridge and St Paul's rival any paid viewpoint.
Entry is free but should be booked online, and slots go fast. There are bars and restaurants inside if you want to linger.
Good to know: Book a slot near sunset as soon as the next batch of tickets is released.
2. Changing of the Guard at Buckingham Palace — St James's, Westminster & South Kensington
The famous ceremony outside the King's London home, with bands and bearskins.
Best for First-timers · Families
The King's Guard changes at Buckingham Palace at 11am on set days, with a military band and soldiers in red tunics and bearskin hats marching between the palace, Wellington Barracks and St James's Palace.
Stand by the palace railings or along The Mall about 45 minutes early for a clear view. It lasts around 45 minutes.
Good to know: Check the Household Division's calendar the day before; it's cancelled in very wet weather.
3. British Museum — Bloomsbury, Soho & the West End
The Rosetta Stone, the Parthenon sculptures and Egyptian mummies — all free.
Best for First-timers · Families · Budget
The British Museum is free and open daily, with one of the greatest collections of human history anywhere. The Egyptian galleries, the Parthenon sculptures and Sutton Hoo are must-sees.
Treat it as a place to come back to rather than one to conquer — an hour on a single civilisation is better than three exhausting hours.
Good to know: Book a free timed slot online at weekends to skip the walk-up queue.
4. National Gallery — Trafalgar Square, Soho & the West End
Van Gogh, Turner and Titian for free, on London's best-known square.
Best for First-timers · Couples · Budget
The National Gallery's collection of European paintings is free, from medieval altarpieces to Van Gogh's Sunflowers and Monet's water lilies.
Step out onto the portico for the view down Whitehall to Big Ben, then cross Trafalgar Square to see the street performers and the Fourth Plinth's latest artwork.
Good to know: Friday late openings are the calmest time to see the most famous rooms.
Dinosaurs and the blue whale skeleton, free in a spectacular Victorian building.
Best for Families · Budget
The Natural History Museum is free and London's favourite day out with children: dinosaurs, the blue whale in Hintze Hall, volcanoes and earthquakes, and a beautiful wildlife garden.
The Science Museum and the V&A, also free, are next door.
Good to know: Arrive at opening time in school holidays; queues build fast by late morning.
6. The South Bank walk — Westminster Bridge to Tower Bridge, South Bank & Borough
London's best free walk, past the London Eye, Tate Modern and the Globe to Tower Bridge.
Best for First-timers · Couples · Families
Start at Westminster Bridge, opposite Big Ben, and follow the Thames Path along the south bank: the London Eye, the Southbank Centre's second-hand book market under Waterloo Bridge, Gabriel's Wharf, Tate Modern, Shakespeare's Globe, Borough Market and finally Tower Bridge.
It's about 4km and takes an hour or so without stops — longer if you browse the free galleries on the way.
Good to know: Walk it from west to east in the late afternoon, and end with sunset at Tower Bridge.
Free modern art and a free viewing level over the Thames.
Best for Couples · Budget
Tate Modern's permanent collection is free, and the giant Turbine Hall usually hosts a major installation. The 10th-floor viewing level in the Blavatnik Building gives one of the best free views of the river and St Paul's.
Cross the Millennium Bridge afterwards to St Paul's.
Good to know: Go up to the viewing level first thing, before it fills.
8. Hampstead Heath and Parliament Hill — Hampstead
Wild heathland and a classic view over the whole London skyline.
Best for Couples · Families · Budget
Hampstead Heath is 320 hectares of meadows, woods and ponds, far wilder than any central London park. Parliament Hill, on its southern edge, has a protected view of St Paul's, the Shard and the City towers.
Walk north across the heath to Kenwood House, which is free to enter and has Rembrandt and Vermeer paintings, then finish in Hampstead village.
Good to know: Take the Overground to Hampstead Heath or Gospel Oak station for the shortest walk up Parliament Hill.
A Royal Park with one of the best views in London, next to the Prime Meridian.
Best for Families · Couples · Budget
Greenwich Park climbs from the river to the Royal Observatory. From the top of the hill, by the General Wolfe statue, you see the Queen's House and the old Royal Naval College in the foreground and Canary Wharf and the City beyond.
The National Maritime Museum and the grounds of the Old Royal Naval College are free to wander, and Greenwich Market is at the foot of the hill.
Good to know: The Prime Meridian line runs through the observatory's paid courtyard, but there's also a free marker on the path outside.
10. Sir John Soane's Museum — Holborn, Soho & the West End
A free, eccentric house-museum crammed with antiquities, Hogarths and an Egyptian sarcophagus.
Best for Couples · Solo · Budget
Sir John Soane's house on Lincoln's Inn Fields is exactly as he left it in the 1830s, every wall covered with classical fragments, paintings and architectural models.
Entry is free, but numbers inside are limited, so expect a short queue at busy times.
Good to know: Visit on a weekday afternoon, when the queue is usually shortest.
A bombed-out medieval church turned into a quiet, ivy-covered garden.
Best for Couples · Budget
St Dunstan-in-the-East was damaged in the Blitz and never rebuilt; instead, its walls and Wren tower now enclose a small public garden, with climbing plants growing through the gothic windows.
It's a five-minute walk from the Tower of London and the Sky Garden, so it fits easily into a City afternoon.
Good to know: Go early on a weekday morning for photographs without the crowds.
12. Choral Evensong at Westminster Abbey or St Paul's — Westminster / City of London
Hear one of the world's great choirs in a world-famous church, without paying an entry fee.
Best for Couples · Solo · Budget
Choral Evensong is a sung evening service held in the late afternoon on most days at Westminster Abbey and St Paul's Cathedral. Visitors of any faith are welcome to attend and sit in the choir or nave.
It's a service, not a tour, so you won't be able to wander, but hearing the choir in these buildings is unforgettable.
Good to know: Check service times on each church's website, and arrive 15–20 minutes early to be seated.
The British Museum, National Gallery, National Portrait Gallery, Natural History Museum, Science Museum, V&A, Tate Modern, Tate Britain, the Imperial War Museum, the Wallace Collection and Sir John Soane's Museum are all free. See our full guide to the best museums in London.
Is the Sky Garden really free?
Yes. Free tickets to the Sky Garden are released online a few weeks in advance and go quickly; walk-ins are sometimes possible at quiet times, but don't count on it. Arrive within your booked slot.
When is the Changing of the Guard?
At Buckingham Palace, the Guard Change takes place at 11am on set days of the week (in late 2026, Mondays, Wednesdays and Fridays, with a Sunday parade at 10am on some weeks). The schedule changes, so check the Household Division's online calendar before you go.
Can you go inside Westminster Abbey or St Paul's for free?
Yes, by attending a service. Choral Evensong is held most days in the late afternoon at both, and visitors are welcome — you won't be able to tour the building, but you'll hear the choir in it. Check each church's website for times.
What free things can you do in London with kids?
The Natural History Museum and Science Museum, the Diana Memorial Playground in Kensington Gardens, the Changing of the Guard, and the South Bank's street performers are all free. Markets like Borough and Greenwich are free to browse too.
