London itineraries by trip length
Last updated . Transport, entry and booking details can change. Check the named official sources before travel.
London is too large for a landmark checklist. A good short plan uses the river and Tube to connect compact clusters, then lets the free national collections carry much of the indoor time.
How many days do you need in London?
3 days give a first visit 3 compact zones: Westminster, the City and one museum plus neighbourhood day.
Use contactless payment or Oyster consistently, and swap the outdoor sequence for a museum when the weather turns.

Why this page exists. Every RoamWeek page has to say something true of it and false of its siblings. For London that is the question of how long to stay, which the duration pages below answer one length at a time.
