Why go to London
London is expensive, grey more often than anyone admits, and the Tube can be unpleasant at 8:30 on a weekday. You should still go. Few cities pack this much into one place: world-class museums that cost nothing to enter, a thousand years of history on a single riverbank, and a food scene that now rivals anything in Europe. Then there are the pubs, the parks and the theatres.
It also works well for flight deals. Five airports and heavy competition between carriers mean fares from most of Europe, and plenty of long-haul routes, drop low if you stay flexible on dates. Spend the savings on a good dinner.
What to see: the places worth your time
- British Museum (Bloomsbury): free, enormous, and best tackled in a focused two hours. Go for the Rosetta Stone, the Parthenon sculptures and the Egyptian galleries. Skip the rest unless you have a spare afternoon.
- Tower of London: the Crown Jewels and the Beefeater tours justify the ticket. Arrive at opening time, because the queue for the jewels builds fast.
- Westminster and Big Ben: Parliament, the Abbey and the clock tower are best seen from Westminster Bridge early in the morning, before the crowds. Go inside the Abbey only if history is your thing, as it is pricey.
- Tate Modern and the South Bank: a former power station full of modern art, free to enter. Afterwards, walk east along the river towards Borough Market and Shakespeare's Globe.
- St Paul's Cathedral: climb the dome for the view over the City. Then cross the Millennium Bridge to the Tate for the classic sightline.
- Tower Bridge: look at it from the riverside path rather than paying to go up, unless you want the glass walkway.
- Greenwich: take a Thames Clipper boat there. You get the Royal Observatory, the Cutty Sark, the park, and one of the best views of Canary Wharf and the City from the hill.
- Victoria and Albert Museum and the Natural History Museum (South Kensington): both free and both spectacular buildings. Pick one if you are short of time. The V&A suits adults, the Natural History Museum suits families.
- Kew Gardens: a proper half-day out in the southwest, especially good in spring and on grey days when the glasshouses earn their keep.
Things to do beyond the checklist
Book a West End show. Same-day deals are sold at the TKTS booth in Leicester Square, and the box offices of the theatres themselves often hold cheap returns. Walk the Regent's Canal from Camden to Little Venice, which gives you houseboats, locks and a surprisingly calm hour or two. Climb Parliament Hill on Hampstead Heath at sunset, because the skyline view is free and far less crowded than anything paid.
Visit the Sky Garden for a free panorama (booking is required, so reserve ahead). Spend a Saturday morning at Portobello Road Market in Notting Hill, then walk the pastel streets before the selfie queues thicken. If you can get a ticket, a Premier League match is a better cultural education than most tours. And have a pint in an old pub, preferably one with a fireplace and no music.
How many days and a suggested route
Three days is the minimum for the main sights, four is comfortable, and a week lets you see the city rather than just its landmarks. Here is a four-day plan that avoids too much zigzagging.
- Day 1, Westminster and the South Bank: Parliament, the Abbey, a walk along the river, the Tate Modern, then Borough Market for lunch or an early dinner.
- Day 2, the City and the east: St Paul's, the Tower of London, Tower Bridge, then Shoreditch and Brick Lane for the evening.
- Day 3, Bloomsbury, Soho and the West End: British Museum in the morning, Covent Garden, Soho for dinner, and a show.
- Day 4, choose one: Greenwich by boat, South Kensington museums plus Hyde Park, or Kew Gardens.
When to go
May, June and September are the sweet spot, with long daylight, mild temperatures around 16 to 22°C and lighter crowds than July and August. Summer can reach the high twenties, and the Tube has little air conditioning, so be warned. Spring brings blossom in the parks. Winter is cold but rarely freezing, typically 3 to 8°C, and it gets dark by about 4 pm. December has the lights and markets but also the highest hotel prices. Rain can arrive in any month, so pack a light waterproof and comfortable shoes whatever the forecast says.
Where to stay
London is big, so location matters more than a pretty hotel room. Look for somewhere near a Tube or Elizabeth line station and you will save an hour a day.
- Bloomsbury and King's Cross: central, quiet at night, and well connected for the airport and Eurostar. Good mid-range hotels and some solid hostels.
- South Bank and Southwark: great for walking to the main sights, with decent chain hotels and a lively evening scene around Borough.
- Soho and Covent Garden: ideal if you want theatres and restaurants on your doorstep, but pricey and noisy at weekends.
- Shoreditch and Hackney: better for nightlife, street food and independent shops, with more characterful and often cheaper stays.
- Kensington and Paddington: comfortable, residential and handy for the Heathrow trains.
As a rough guide, a dorm bed costs about £25 to £45 a night, a decent mid-range room £110 to £200, and anything on the grander side starts well above that.
What to eat and where
Start with a proper full English breakfast in a neighbourhood café, not a hotel buffet. For lunch, Borough Market is crowded but still excellent, so go on a weekday. Fish and chips from a decent chippy beats a tourist-trap pub version every time, and a classic Sunday roast in a good pub is a ritual worth keeping if you are here on the right day.
The real strength of London is its range of cuisines. Try a curry on Brick Lane or in Southall, a bowl of ramen in Soho, or Turkish grills in Dalston and Green Lanes. Dishoom, the Bombay-style café group, is deservedly popular, but expect a queue at peak times. At Beigel Bake on Brick Lane, a salt beef bagel at 2 am is a London rite of passage. For something old-school, try pie and mash at a traditional shop such as Manze's. A pint typically costs £5 to £7.
Getting from the airport and getting around
From Heathrow, the Elizabeth line is the best value, running to Paddington, Tottenham Court Road and Liverpool Street in about 30 to 40 minutes. The Heathrow Express is faster to Paddington but costs more, and the Piccadilly line is cheapest but slower. From Gatwick, take the train to Victoria or London Bridge. From Stansted, the Stansted Express runs to Liverpool Street. From Luton, shuttle to Luton Airport Parkway, then take a Thameslink train into central London.
Once in the city, use the Tube, buses and trains with a contactless card or phone. You do not need an Oyster card, and daily fare capping means you will not overpay. Buses are slow but scenic, and the Thames Clipper is a good option for Greenwich. Walk when you can, because the centre is more compact than the map suggests. Avoid driving entirely.
Rough daily budget
- Tight: £70 to £100, with a hostel, supermarket meals, free museums and public transport.
- Mid-range: £150 to £250, with a comfortable hotel, a couple of paid sights, a pub lunch and a good dinner.
- Comfortable: £300 and above, with a central hotel, theatre tickets and sit-down restaurants.
Flights are often the cheapest part. The city itself is what drains the wallet, so plan your free museums and paid attractions around each other.
FAQs
Is London too expensive for a short trip?
It can be, but the free museums, parks and walking routes make it manageable. Accommodation is the main cost, so book early and stay near a station rather than in the middle of the West End.
Do I need a visa or electronic authorisation?
It depends on your nationality, and the rules for the UK have changed in recent years. Many visitors now need an electronic travel authorisation before travelling, so check the official UK government website well before you fly.
Which airport is best for London?
Heathrow has the best rail links, and Gatwick is a close second. Stansted and Luton are often cheaper to fly into but add time and cost on the way into town, so compare the total.
Is the Tube safe and easy to use?
Yes, and it is the fastest way across the city. Use common sense at night, stand on the right on escalators, and avoid peak hours (around 8 to 9:30 am and 5 to 7 pm) if you can.
Should I buy a London Pass?
Only if you plan to visit many paid attractions in a short time. With free museums and a few chosen paid sights, buying individual tickets usually works out cheaper.
