Free things to do in London

Free in London means two things: sights with no entry charge, and paid sights you can enjoy from outside. The first group is the strongest in Europe — the national collections are free by policy, so a rainy Tuesday costs you nothing but a bus fare.

Plan one museum per half-day. The British Museum and National Gallery each need two to three hours minimum; the V&A and Tate Modern reward a shorter first visit. Arrive at opening, when the tour groups have not yet filled the rooms.

Most free sights cluster in three walkable zones. Zone 1: Bloomsbury (British Museum) to Trafalgar Square (National Gallery, National Portrait Gallery), about 20 minutes on foot. Zone 2: South Kensington (V&A, Natural History, Science museums), all within five minutes of each other. Zone 3: the South Bank, from Westminster Bridge to Tower Bridge, free to walk end to end in about an hour.

The parks connect the middle: St James's Park sits between Buckingham Palace and Westminster, Hyde Park runs west from Marble Arch to Kensington, and the walk from Green Park through St James's Park to the river takes about 25 minutes.

Entry is free, but donations are invited and most museums suggest £5. Temporary exhibitions are the main paid add-on and often sell out at weekends, so book ahead if a specific show matters to you.

Transport is the real cost. A contactless card or phone works on buses and the Tube; buses are £1.75 per ride with a hopper fare that lets you take a second bus within an hour for free (2026 estimate). Walking between Bloomsbury, Trafalgar Square and the South Bank is often faster than the Tube.

Free sights with timed entry — Sky Garden, and the big museums in peak season — need booking online, sometimes days ahead. Bring a refillable bottle; park and museum fountains are free, and cafés will usually refill for nothing.

For a rainy day, the South Kensington museums absorb crowds best because there are three of them side by side. On a sunny day, do the parks and the South Bank walk instead and save the museums for the next wet morning.

May to September gives the best odds for parks, markets and the South Bank walk, with long daylight until around 21:00 in June and July. This is also peak season, so the free museums fill up; go at opening or after 15:00.

October to March is colder and darker but quieter, and the free indoor sights carry the trip. December brings free lights along Oxford Street and Regent Street, plus crowds. Sundays are best for Columbia Road Flower Market and quietest for the City, which empties out at weekends.
