Four days is an ideal first visit to London — enough to cover the royal and historic icons, the world-class (and free) museums, the South Bank's culture, and a West End show, with time to enjoy the parks and markets. This itinerary groups the sights geographically across four days so you spend your time exploring rather than crossing the sprawling city on the Tube.
It assumes you arrive into one of London's airports — see our Heathrow airport guide for the easiest routes in. For where to base yourself, see where to stay in London, and for more ideas, things to do in London. Day-trip planning is easy with our distance calculator.
May to September brings the warmest, longest days and the liveliest atmosphere, though it is busiest. Spring and early autumn are pleasant and quieter; December is festive with Christmas lights and markets. London is a year-round city with plenty of indoor sights for wet days.

Is 4 days enough for London?
Four days is a great length for a first visit — enough to cover the royal and historic icons, the major free museums, the South Bank, and a West End show, with a flexible fourth day for parks, markets, or a day trip. London is vast, so even a week rarely feels too long, but four days captures the essentials at a reasonable pace.
What should I not miss in 4 days in London?
The essentials are Westminster (Big Ben, the Abbey, Buckingham Palace), the Tower of London and Tower Bridge, the British Museum, the South Bank, and a West End show. This itinerary covers them grouped by area across four days, with a flexible final day for Kensington, Notting Hill, or a day trip to Windsor.
How do you get around London?
The Underground (Tube) is the backbone, supplemented by buses, with central areas very walkable. Tap in and out with a contactless bank card — daily fare capping means you never pay more than a day pass. Grouping sights by area, as this itinerary does, minimises Tube time across the large city.
Are London museums really free?
Yes — most of London's major museums, including the British Museum, the Natural History Museum, the Victoria and Albert Museum, and Tate Modern, are free to enter, though special exhibitions and some attractions charge. This makes London excellent value for culture lovers; focus on a few highlights per visit rather than trying to see everything.
Should I do a day trip from London with only 4 days?
Only if a specific destination appeals, as it trades a day of central London for the excursion. This itinerary offers it as a flexible option on day four — Windsor Castle, Oxford, and Greenwich are all easy half- or full-day trips. With four days, many first-timers prefer to focus on the city and save day trips for a longer stay.

May to September brings the warmest, longest days and the liveliest atmosphere, though it is the busiest and priciest.
