London Travel Guide 2026 — Everything You Need to Know

London rewards planning more than almost any European capital. It is huge, it is expensive if you let it be, and the difference between a well-organised trip and a chaotic one is enormous. This guide covers the practical decisions — airport, transport, neighbourhood, budget and timing — plus what is genuinely worth your time once you are there.

Which Airport to Fly Into

London has six airports and they are not interchangeable. Heathrow (LHR) is the largest and best connected to the centre, on the Piccadilly line and the Elizabeth line. Gatwick (LGW) is further south but has fast, frequent trains to Victoria and London Bridge. City (LCY) is tiny, closest to the centre, and brilliant if your airline flies there.

Stansted (STN) and Luton (LTN) are where most low-cost carriers land, and both are genuinely far out — budget an hour and £20–25 each way. A £15 saving on the fare disappears quickly. Southend (SEN) is furthest of all. When comparing fares, always add the transfer cost and time before deciding.

Getting Around

Do not buy an Oyster card. Just tap a contactless bank card or phone on every reader — the fare is identical, daily and weekly caps apply automatically, and there is nothing to buy or top up. Tap in and out on the Tube and rail; tap only once on buses.

The Tube is fast but the map distorts distances badly — Covent Garden to Leicester Square takes longer underground than on foot. Central London is far more walkable than visitors expect, and walking is how you actually see the city. Buses are cheaper than the Tube, capped separately, and give you a view.

The Elizabeth line has transformed east–west journeys and is worth knowing about; it connects Heathrow, the West End, the City and Canary Wharf quickly.

Where to Stay

Location matters more than the hotel. South Bank and Southwark put you walking distance from the Tate Modern, Borough Market and the river, with better value than the West End. Bloomsbury and King's Cross are central, well connected and quieter at night. Shoreditch for nightlife and food, Notting Hill and Bayswater for a calmer, more residential stay.

Staying two or three Tube stops out of Zone 1 typically saves a substantial amount for very little inconvenience. Avoid booking somewhere purely because it is cheap without checking the transport links — a bargain in Zone 4 is not a bargain.

What Costs Money and What Doesn't

London's greatest bargain is that its major museums are free. The British Museum, National Gallery, Tate Modern, Natural History Museum, V&A and Science Museum all cost nothing to enter, and any one of them could fill a day. Special exhibitions are ticketed; the permanent collections are not.

Also free: the parks (Hyde Park, Regent's Park, Hampstead Heath for the best view in London), the changing of the guard, Borough Market to wander, the South Bank, Sky Garden if you book a slot in advance, and most of the city's finest architecture from the outside.

What genuinely costs: the Tower of London, Westminster Abbey, St Paul's, the London Eye and West End theatre. Pick two or three rather than trying to do all of them. For theatre, day seats and the TKTS booth in Leicester Square cut prices substantially over booking ahead at face value.

Eating Well Without Overpaying

London's food scene is genuinely world-class now, and the value sits at the informal end. Borough Market, Maltby Street and Brick Lane for street food; the city's Indian, Turkish, Vietnamese and West African restaurants for some of the best cooking anywhere at moderate prices. A proper curry on Brick Lane or in Tooting costs a fraction of a mediocre tourist-trap meal in Leicester Square.

Set lunch menus at good restaurants are the single best value in the city — often half the price of the same kitchen's dinner. And a pub lunch remains one of London's great institutions.

When to Go

May, June and September are the best months: long days, decent weather and the parks at their best. July and August are warm but busy and expensive, and the city empties of locals. Winter is dark and damp but genuinely cheap — January and February have the lowest flight and hotel prices of the year, and the museums are free regardless of weather, which makes London an unusually good cold-season city break.

December is the exception: Christmas lights and markets push prices back up sharply.

Practical Notes

• Stand on the right on Tube escalators. This is not a suggestion.
• Tipping is 10–12.5% in restaurants and often added as a service charge — check before adding more. No tipping in pubs when ordering at the bar.
• Contactless everywhere. Cash is genuinely unnecessary; many places no longer take it.
• Three days minimum. London is too big to sample in a weekend and still feel you have seen it. Five days lets you add Greenwich, Hampstead or a day trip.
• Book the big-ticket sights ahead. The Tower, Westminster Abbey and popular exhibitions sell out, and on-the-door prices are higher.

Getting There Cheaply

London is one of the best-connected cities on earth, which keeps fares competitive year-round. January and February are consistently the cheapest months to fly in, and midweek departures beat weekends as everywhere. With six airports competing, it is always worth checking more than one — but factor the transfer honestly, because the cheapest fare into Stansted is not always the cheapest way to reach London.
