Is three days enough to see London's main sights?

It comfortably covers the major landmarks if grouped by area, though London has far more to offer than three days can show. Expect to prioritise rather than see everything.

Do I need to book tickets in advance?

Major paid attractions and popular timed-entry museum slots are worth booking online ahead, especially for weekends and school holidays, to reduce waiting time.

What's the best way to get around during the trip?

Contactless payment or an Oyster card on the Tube, buses and DLR, with fares capped daily across Zones 1-2, is generally the simplest approach for a short stay.

London in 3 Days: A Practical Itinerary for 2026

Three days is enough to see central London's main landmarks without rushing between every corner of the city. This itinerary groups sights by area to cut travel time, leaving room for meals, queues and the odd delay. Adjust the order to match your accommodation and interests.

Day 1: Westminster and the South Bank

Start at Westminster Abbey and the Houses of Parliament before walking the South Bank past the London Eye and Tate Modern. Cross the Millennium Bridge to St Paul's Cathedral in the afternoon. Buy tickets for paid attractions online in advance where possible to skip queues at busy entrances.

Day 2: The City, the Tower and the British Museum

Spend the morning at the Tower of London, then walk across Tower Bridge towards the City's skyscrapers. In the afternoon head to the British Museum, whose permanent galleries are free to enter. Evening options include Covent Garden or a West End show booked ahead of time.

Day 3: Greenwich or Camden and Notting Hill

Take the DLR to Greenwich for the Royal Observatory, the Cutty Sark and the Prime Meridian line, or choose Camden Market and Notting Hill's Portobello Road for a different pace. Both routes work well with contactless pay as you go or a day travelcard.

Practical tips for timing and transport

Use contactless or Oyster for the Tube, DLR and buses; fares cap automatically each day across Zones 1-2. Allow extra time for security checks at major attractions and for queues around midday. Comfortable shoes matter more than a tight schedule across three packed days.
