London is an easy, rewarding first stop in Europe for Americans: no language barrier, nonstop flights from many US cities, and an astonishing number of world-class museums that are free to enter. Add royal palaces, West End theater, historic pubs and markets, and four or five days fly by.
The city is huge, so group your days by area: Westminster and the South Bank, the City and the Tower, museums in South Kensington, and the West End. Since January 2025, US citizens need a UK Electronic Travel Authorisation (ETA) before traveling; apply on the official GOV.UK site or app.

- The Elizabeth line and Heathrow Express link Heathrow to central London; Gatwick Express serves Gatwick.
- Walking between neighboring sights is often faster than the Tube.
Budget tips for London
- Many major museums are free; spend on paid sights like the Tower of London selectively.
- Use contactless payment for automatic daily fare caps.
- Eat at markets and pubs at lunch; pre-theater menus offer value at dinner.
- Stay in Bloomsbury or King's Cross for good-value, central hotels.
Insider tips for London
Many attractions offer cheaper online tickets with timed entry; the Tower of London, Westminster Abbey and the London Eye all reward booking ahead in summer and school holidays.
Use the free museums as your backbone and pick one or two paid highlights per day. Popular special exhibitions at free museums can be ticketed, so check ahead.
London's weather changes quickly, so pack a light rain jacket year-round. Indoor backups like the museums, covered markets and Leadenhall Market make easy rainy-day swaps.
Tipping: a service charge of around 12.5 percent is often added to restaurant bills; if it is, there's no need to tip more. Tipping isn't expected in pubs when ordering at the bar.
