London travel guide
London mixes royal landmarks, world-class museums (many of them free), markets, parks and theatres. First visits usually cover Westminster, the Tower and the South Bank, then a few neighbourhoods.
Best time to visit London
Late spring (May to June) and early autumn (September) usually bring the most pleasant weather. Summer is the busiest season.
Winter is cool and often grey, but museums, theatres and Christmas markets keep the city lively. Rain is possible in any month, so pack a light jacket.
Getting to London
Most flights from the US land at Heathrow (LHR), linked to central London by the Elizabeth line, the Piccadilly line and the Heathrow Express. Gatwick (LGW) is served by fast trains to Victoria and London Bridge.

Getting around
The Tube and trains
The Underground reaches most sights. Tap a contactless card or phone at the gates instead of buying paper tickets; daily fares are capped automatically.
Buses
Red double-deckers are a good way to see the city; they are cash-free, so use contactless.
On foot and by river
Central areas are close together, and Thames riverboats link Westminster, the South Bank, the Tower and Greenwich.
