Londres, Royaume-Uni Guide de voyage

London is enormous: 32 boroughs spread across a slow bend of the Thames, and a city of distinct neighborhoods rather than one center. First trips tend to cluster in the West End, Westminster and along the South Bank.

The most common complaints in traveler reports are the prices (the London Eye, Madame Tussauds, tourist-strip restaurants) and the crowds at the handful of famous spots. The upside is that London has more free, world-class places than almost any city: most major museums charge nothing, and so do the small museums, gardens and walks that Londoners actually recommend.

This guide leads with those, then covers what to skip or swap, and how to get around without overpaying.

None of these appeared in the top "best things to do in London" results, and all six are recommended again and again by Londoners, local media and heritage sources. All are free.

Sir John Soane's Museum. The house of the architect of the Bank of England, left exactly as he arranged it: every wall and alcove packed with antiquities, paintings (including Hogarth's A Rake's Progress) and an Egyptian sarcophagus. It's on Lincoln's Inn Fields in Holborn, open Wednesday to Sunday, 10am–5pm. It's small, so book a timed slot on the museum's website.

St Dunstan-in-the-East. A medieval church rebuilt after the Great Fire, bombed in the Blitz, and turned into a public garden in 1971. Wren's tower survived, and ivy and trees now grow through the empty Gothic windows. It's between the Tower of London and London Bridge, so it fits a Tower morning easily.

Postman's Park. A small garden near St Paul's with G.F. Watts's Memorial to Heroic Self-Sacrifice: 62 people who died saving others, each remembered on a hand-lettered ceramic tablet. It takes five minutes and stays with you.

Parkland Walk. A 4.5-mile (7.2 km) disused railway line turned local nature reserve, running from Finsbury Park toward Highgate and Alexandra Palace. The old Crouch End station platforms still stand in the trees. Start at Finsbury Park station and walk north.

The Horniman Museum and Gardens. A free Arts and Crafts museum in Forest Hill, south London (Art Fund Museum of the Year 2022). It holds natural history, musical instruments and an aquarium (the aquarium charges), and its gardens look across to the City skyline. Open daily, 10am–5:30pm.

The Wallace Collection. A Marylebone townhouse full of Old Masters (Rembrandt, Titian, Hals's Laughing Cavalier), French furniture and armour. It's free, open daily from 10am to 5pm, rarely crowded, and five minutes from Bond Street when Oxford Street gets too much.

Skip: Leicester Square and M&M World. Instead: Seven Dials, a few streets away. Leicester Square tops most "tourist trap" lists for its chain restaurants and crowds. Seven Dials and the Covent Garden back streets have independent shops and better food.

Skip: the London Eye as your skyline view. Instead: Sky Garden (free, booked ahead) or Primrose Hill at sunset. The Eye is one of London's more expensive tickets and queues can be long. Sky Garden's viewing floors at 20 Fenchurch Street are free but need a timed booking; weekend sunset slots are released about three weeks ahead and go fast.

Skip: the crush at Buckingham Palace. Instead: the Household Cavalry changing guard at Horse Guards Parade. It happens at 11am (10am on Sundays), with smaller crowds and no railings between you and the horses. The Buckingham Palace ceremony only runs on certain days, so check the British Army's schedule before planning around it.

Skip: Madame Tussauds. Instead: any of the free museums above. Reports consistently call it overpriced for what it is.

May to September brings the longest days (sunset after 9pm around the June solstice), outdoor events, and parks at their best. It's also peak season for hotel prices.

Spring and autumn (April, and September to October) are milder and quieter, and still good for walking.

Winter is grey and dark by 4pm, but it's cheaper, the museums are warm and free, and the Christmas lights and markets run from late November.

It rains year-round, usually in short bursts rather than all day. Carry a light waterproof whatever the season.

Tap a contactless card or phone. Don't buy an Oyster. Contactless pays exactly the same fares as Oyster and caps automatically: a day of Tube and bus travel in zones 1–2 is capped at £8.90 (2026). A visitor Oyster card adds a non-refundable fee.

From Heathrow: the Elizabeth line costs £15.50 to central London (2026) and takes about 30 minutes to Paddington, then continues through the West End and the City without a change. The Heathrow Express is faster to Paddington but costs £25 and doesn't count toward your daily cap.

Walk between neighboring stations. In the West End, many stops (Leicester Square and Covent Garden, for example) are closer on foot than by train.

Buses are cheap and scenic: a flat fare, capped with the Tube, with top-deck views. Always stand on the right on Tube escalators.

South Bank and Bankside. Along the river, walkable to Westminster, the Tate Modern and the City, with good transport. A strong first-trip base.

Covent Garden and Soho. The center of everything: theatres, restaurants, nightlife. Expensive and noisy, but you'll walk everywhere.

Marylebone and Fitzrovia. Central but calmer, with village-like high streets, the Wallace Collection, and Regent's Park and Primrose Hill nearby.

King's Cross. Excellent transport (Eurostar, six Tube lines, direct trains to Luton and Gatwick airports) and a rebuilt canal-side district with good restaurants.

Buying an Oyster card or paper tickets. Contactless is the same price and caps itself. The only exception is if your card charges foreign transaction fees.

Using two cards. Caps only apply per card, so tap the same card or phone every time. Switching between your phone and your physical card can mean paying twice.

Paying for views and waxworks. London's free museums and viewpoints are better than most paid ones. Budget for the Tower of London and a show, not the Eye and Madame Tussauds.

Booking Sky Garden on the day. Free slots, especially at sunset, go weeks ahead.

Standing on the left on escalators. Stand right, walk left. Londoners will notice.

One day

Start at the Tower of London when it opens, then walk to St Dunstan-in-the-East and on to St Paul's, with Postman's Park next door. Cross the Millennium Bridge to Tate Modern and walk the South Bank to Westminster. Finish with the view from Sky Garden if you booked it.

Two days

Day two: spend the morning at the Wallace Collection and walking Marylebone, then Regent's Park up to Primrose Hill for the view. Spend the evening in Soho or Seven Dials.

Three days

Day three: start at Sir John Soane's Museum and the British Museum, then head north to walk the Parkland Walk from Finsbury Park toward Highgate. Or, with kids, go south for the Horniman Museum and Gardens.

How many days do you need in London?

Four to five days covers the major sights, the free museums, and time for a couple of neighborhoods. Three days works if you plan by area.

Should I get an Oyster card in London?

Usually not. Tapping a contactless bank card or phone costs the same, caps daily and weekly fares automatically (£8.90 a day for zones 1–2 in 2026), and has no card fee.

What's the cheapest way from Heathrow to central London?

The Tube's Piccadilly line is the cheapest. The Elizabeth line (£15.50 in 2026) is faster and still much cheaper than the Heathrow Express (£25).

What are the best free things to do in London?

The major museums (the British Museum, National Gallery, Tate Modern), plus Sir John Soane's Museum, the Wallace Collection, the Horniman, St Dunstan-in-the-East, the Sky Garden (booked ahead) and the Household Cavalry guard change at Horse Guards Parade.

Is the London Eye worth it?

It's one of the city's more expensive tickets. For the skyline, the free Sky Garden or Primrose Hill at sunset give you a comparable view without the queue.
