London has more free world-class museums than any other city on earth, alongside icons you'll pay to see and neighbourhoods that reward simply wandering. Here are the 16 best things to do in London in 2026.
The world's greatest collection of human history under one roof — the Rosetta Stone, the Elgin Marbles, Egyptian mummies and the Sutton Hoo helmet. Completely free. Allow a full half-day and arrive early to beat the tour groups.
1,000 years of royal history — the Crown Jewels, the medieval White Tower and Beefeater tours. One of the few major sights that isn't free (£30+), and queues build fast in summer, so book ahead.
The world's most visited modern art museum, free, housed in a converted Bankside power station. The Turbine Hall installations are always striking, and the viewing terrace has one of the best free views of St Paul's Cathedral.
Free entry to see the blue whale skeleton, the dinosaur gallery and the gem vault, all inside an extraordinary Romanesque terracotta building. No booking required for the permanent collection.
London's oldest and finest food market, under the railway arches at London Bridge. World-class street food and artisan producers — busiest Thursday to Saturday, calmer Monday to Wednesday.
Over 40 major productions running simultaneously, making London the world capital of theatre. Day seats and returned tickets are often available at the box office from 10am, or check the TodayTix app for last-minute discounts.
Free entry to the world's finest decorative arts collection, spanning fashion, sculpture, ceramics and design across 5,000 years. Consistently under-visited relative to its quality.
The Victorian bascule bridge that's become one of London's defining images. The exterior is free to view and cross; the glass floor walkway and engine rooms are ticketed separately.
Free entry on Trafalgar Square to one of the world's great collections of Western European painting — Van Gogh, Turner, Da Vinci and Vermeer, all under one roof in the heart of the city.
London's creative heart — street art, vintage markets, the best bagels in Britain at Beigel Bake (open 24 hours), and some of the finest Indian and Bangladeshi restaurants outside the subcontinent.
Pastel-coloured terraced houses and the Portobello Road antiques market (Saturdays). Come August, the neighbourhood hosts Notting Hill Carnival — Europe's largest street festival.
Home of the prime meridian — the Royal Observatory, the Cutty Sark tea clipper, Greenwich Park and the free National Maritime Museum, all 30 minutes from central London by DLR or river boat.
A stretch of railway arches south of the river converted into craft breweries, best explored on a Saturday alongside nearby Maltby Street Market.
Central London's largest green space, free to wander, with Kensington Palace, the Serpentine lake and the Diana Memorial Fountain all within its grounds.
Just outside London — walk through the actual sets, props and costumes from the films. Requires advance booking and transport from central London (coach packages are the easiest option).
A relaxed way to see Big Ben, the London Eye, Tower Bridge and the Tower of London from the water — hop-on hop-off options let you combine sightseeing with transport between riverside sights.
Currency: British Pound (GBP), not euros. Contactless and card payment is near-universal.
Getting around: Get an Oyster card or use contactless directly on the Underground and buses — never buy single paper tickets, which cost significantly more.
Language: English. No language barrier for most visitors.
Is London expensive? Yes — the most expensive major European city for accommodation. The free museum circuit offsets much of this if you plan around it.
How many days do you need in London? 3–4 days covers the highlights. 5–7 days lets you explore neighbourhoods properly and add a day trip.
Do I need to book the Tower of London in advance? Yes, especially June–August — it's one of the few major sights that isn't free and queues build quickly without a pre-booked slot.
