35 Best Free Things to Do in London at Weekends

London has a reputation for emptying wallets, but here’s the secret long-term residents know: some of the best things in this city cost nothing at all. World-class museums with free entry, markets that are free to wander, skyline views that rival paid observation decks, and parks that put most cities’ to shame. I’ve lived here over a decade and my favourite weekends are usually the free ones. Here’s the definitive list.

Museums and Galleries (All Free)

London’s national museums are free — a genuine marvel most cities can’t match:

• British Museum — the Rosetta Stone, Egyptian mummies, two million years of history. Go early to beat crowds.
• Natural History Museum — dinosaurs, the blue whale, stunning architecture. Book free tickets ahead at weekends.
• V&A — fashion, design and decorative arts in South Kensington. The fashion galleries are unmissable.
• Tate Modern — the Turbine Hall alone is worth the trip; the viewing level has free panoramic views.
• National Gallery — Van Gogh’s Sunflowers, free, in Trafalgar Square.
• Science Museum — brilliant for kids and curious adults alike.
• Imperial War Museum — powerful, moving, and free.
• Museum of London Docklands — the city’s story, in a gorgeous old warehouse.
• National Portrait Gallery — freshly refurbished and excellent.
• Wellcome Collection — weird, wonderful medical history near Euston.

Markets to Wander

• Borough Market — free to browse (bring willpower; the smells are a workout).
• Columbia Road Flower Market (Sunday) — flowers, buskers, pure East End theatre.
• Brick Lane & Spitalfields — vintage, street food to window-shop, street art.
• Camden Market — touristy but still fun for people-watching.
• Greenwich Market — crafts and antiques in a World Heritage setting.
• Portobello Road (Saturday) — antiques, food stalls, Notting Hill charm.

Parks, Views and Walks

• Primrose Hill — the classic free skyline view, best at sunset.
• Greenwich Park — stand on the Meridian Line, look across to Canary Wharf.
• Hampstead Heath — wild swimming ponds (small fee for some), Parliament Hill views, proper countryside in zone 2.
• Richmond Park — deer, ancient oaks, and King Henry’s Mound view to St Paul’s.
• The South Bank walk — Westminster to Tower Bridge along the Thames, street performers included.
• Regent’s Canal towpath — Little Venice to Camden, houseboats and herons.
• Sky Garden — free if you book ahead; 35 floors up with gardens and views.
• Horizon 22 — London’s highest free viewing platform, book online.
• Leake Street graffiti tunnel — legal street art under Waterloo, constantly changing.

Quirky and Unexpected

• Changing of the Guard at Buckingham Palace (check schedule).
• Sir John Soane’s Museum — an architect’s treasure-house, free.
• God’s Own Junkyard (Walthamstow) — neon wonderland, small donation.
• Free lunchtime concerts at St Martin-in-the-Fields.
• The Ceremony of the Keys at the Tower (free but book months ahead).
• Speaker’s Corner (Sunday) — Hyde Park’s free-speech theatre.
• Daunt Books, Marylebone — browsing the world’s most beautiful bookshop costs nothing.

The Best Free Things for London Weekends: A Plan

The trick is combining: museum morning + market lunch (window shopping) + park sunset = a full, rich day for the price of a coffee. Pack a picnic from home — our meal planning guide makes this cheap — and use the bus (£1.75 with the Hopper fare) rather than the Tube. Check our cheapest commuting guide for getting around on a budget.

Free weekends are also how you meet people without the pressure of expensive plans — see making friends as an adult in London. Some of my closest friendships started on free museum trips and park walks.

Free London by Season

Spring

Cherry blossom at Greenwich Park and Kew’s pagoda (park entry charges apply at Kew, but the blossom spotting is free elsewhere), lambing season at Mudchute Farm (free), the Oxford-Cambridge Boat Race along the Thames (free riverside viewing), and St James’s Park pelicans at feeding time (2:30pm daily, free, delightful).

Summer

Outdoor swimming at Hampstead ponds and Brockwell Lido, free outdoor cinema and theatre (check Time Out listings), the Notting Hill Carnival (free, August bank holiday — go early, leave before dark), Proms in the Park screenings, and long evening walks along the Thames at golden hour.

Autumn

Westonbirt-style colour at Richmond Park and Hampstead Heath (free), the Lord Mayor’s Show (free, November), Bonfire Night displays in parks (many free), and museums as the weather turns — the V&A’s fashion galleries hit differently in autumn light.

Winter

Christmas lights (Oxford Street, Regent Street, Carnaby — free to wander), Winter Wonderland’s entry (free; rides/attractions cost), ice skating spectating at Somerset House (skating costs, watching is free and arguably better), carol services (many free, arrive early), and the city’s cosiest free activity: a long museum day followed by a flask of tea on the South Bank.

Free London With Kids

London is staggeringly good for free family days: the Natural History and Science Museums (book ahead), Diana Memorial Playground (free, book), Mudchute Farm, the Diana Memorial Fountain (paddling!), Coram’s Fields (under-16s only — adults must be with a child), the V&A Museum of Childhood (Young V&A), and the Emirates Air Line cable car (not free, but kids love it — pair with a free Greenwich day). Pack lunch, use the bus, and a family day out costs less than the cinema.

Making Free Feel Like a Treat

The psychology matters: a free day planned with care beats an expensive day done by default. My formula — pick one anchor (a museum, a market, a walk), add one food element (a picnic, a specific bakery, a £3 street-food treat), and finish with a view (Primrose Hill, Sky Garden, the South Bank at dusk). It feels like an occasion because it is one. The couples and families I know who love London most aren’t the biggest spenders — they’re the most deliberate planners. And if you’re new here and building a social life, our making friends guide pairs perfectly with this list: invite someone along.

The Practical Takeaway

Living in an expensive city doesn’t mean spending expensively. London’s free offering — museums, markets, parks, views, walks — genuinely rivals what other cities charge for. Rotate through this list and you could fill a year of weekends without repeating yourself or spending more than transport and a packed lunch. The city rewards curiosity more than cash; get out there and collect the free stuff.
