Best Free Things to Do in London

By WhatAreTheTop.Best Editorial TeamUpdated 9 min read

London is one of the most expensive cities in the world, yet some of its finest experiences cost nothing at all. The best free things to do in London range from national museums holding treasures of every civilisation to a rooftop garden with sweeping skyline views, and the capital rewards budget travellers who know where to look. We compared and ranked the city's free attractions on the quality of the experience, how reliably free entry actually works, and how easy each is to reach and book. Note that 'free' here means free general admission or entry: blockbuster temporary exhibitions are almost always ticketed and paid, and a few museums invite an optional donation.

Is it worth your time?

What decides whether a place earns a slot in a busy day — weigh these against your plan.

Is the experience worth a slot?Matters most
A world-class museum or a one-of-a-kind view earns a place in a busy day; a lesser stop may not. Rank the must-sees before you fill the gaps.
How long it takesMatters most
A sprawling museum can swallow half a day, while a rooftop view is a fixed hour. Match each stop to how much of your day you can give it.
Booking & free accessWorth weighing
‘Free’ usually means free general admission — blockbuster shows are ticketed. A few stops need a free timed ticket booked weeks ahead (Sky Garden); most are walk-in.
Location & combiningWorth weighing
The best free days cluster nearby stops together — South Kensington's museums, the South Bank walk, or royal-London parks — so you spend time seeing, not travelling.
Crowds & timingMinor
Weekday mornings at opening, late Friday openings and the last hour before closing are the calmest windows at the big museums.

The picks in depth

WATTB PickBest overall

The British Museum

WATTB98/100

Why it won

One of the most rewarding free days out in London, spanning two million years of human history.

World-class collection that would cost a fortune to see anywhere else

Free timed tickets, and quiet weekday mornings often allow walk-in

Superb central location with three tube stations within a short walk

Trade-off: Enormous and often crowded — you cannot see it all in one visit

Free (indicative; special exhibitions charge)

Why it ranks here

  • You're happy to plan a route around a huge collection

Skip it if

How to choose

Free means free entry — not everything

General admission is free at all five, but blockbuster temporary shows are ticketed (the British Museum's Bayeux Tapestry loan runs Sep 2026–Jul 2027 as a separate paid ticket), and food, drink, deckchairs and boating cost extra. Budget for the extras you actually want.

String stops into one free day

Cluster by area: South Kensington chains the Natural History Museum with the free Science Museum and V&A; Tate Modern anchors a South Bank walk to the Millennium Bridge and St Paul's; Hyde Park flows into Kensington Gardens and St James's Park for royal London.

Frequently asked questions

Are museums in London free to visit?

Yes. The UK's national museums and galleries — including the British Museum, Natural History Museum, Science Museum, V&A, National Gallery and Tate Modern — offer free entry to their permanent collections. However, headline temporary exhibitions are almost always ticketed and paid, and some museums invite an optional donation. Prices for special shows vary, so check each museum's official site before you go.

Do you need to book free things to do in London in advance?

It depends on the attraction. The Royal Parks and most permanent museum collections need no booking, though a free timed ticket is recommended for busy museums at weekends and school holidays. The Sky Garden is different: a free timed ticket is strongly recommended (released on a rolling basis about three weeks ahead, usually Mondays) and slots go quickly, though limited walk-ins are sometimes available subject to capacity. Always confirm current arrangements on the official website, as these change.

What is the best free view in London?

For our money the Sky Garden at 20 Fenchurch Street gives the best free view — a wide panorama over the City with an open-air terrace, at no cost beyond an advance-booked timed ticket. Tate Modern's Level 10 is a good free alternative (though three-sided since a privacy ruling), and Primrose Hill and Parliament Hill on Hampstead Heath offer classic free skyline views.

Can you watch the Changing of the Guard for free?

Yes. The Changing of the Guard at Buckingham Palace is free to watch from the public areas around the palace and along The Mall, with St James's Park offering some of the best vantage points. It does not run every day, and the schedule changes seasonally and with weather, so check the official Household Division or Royal Family website for dates and times before travelling.

What are the best free things to do in London besides museums?

Plenty. The National Gallery on Trafalgar Square, the V&A and Science Museum in South Kensington, the Wallace Collection, the National Portrait Gallery, Tate Britain and the Imperial War Museum are all free to enter. Beyond museums, browsing Borough Market, walking the South Bank, exploring the historic City churches, and heading to Greenwich for the park, riverside and the Prime Meridian courtyard all cost nothing. It's easy to string several free stops into a single day.

What is the best time to visit London's free museums to avoid crowds?

Weekday mornings right at opening (around 10am) are quietest, as are the last couple of hours before closing. Weekends, school holidays and rainy days are busiest, when even free museums that don't normally need booking can hit capacity. Some — like the British Museum on Friday evenings — offer late openings that are noticeably calmer. Booking a free timed slot where offered guarantees entry at peak times.

What the evidence shows

Rankings draw on each attraction's official visitor information and opening hours, current free-booking arrangements checked on providers' own sites, and Visit London, plus our editorial assessment of experience quality and reliability of free access. We have not visited these attractions ourselves.

Limitations

  • Opening hours and free-ticket release timings change — confirm on the official site before you go.
  • Tate Modern's Level 10 view reopened on only three sides (south closed) after a privacy ruling.
