London Off the Beaten Path: 4 Day Itinerary
Four days adds a South Bank day to the three-day plan below, still entirely inside zones 1 to 3 with no rental car and no day trip out to Windsor. Tighter on time? Drop to the 3 day version ; got a full week? See the one week offbeat itinerary instead.
| Day | Focus |
|---|---|
| 1 | Bloomsbury’s free museums, done right |
| 2 | The Square Mile, London’s oldest secret |
| 3 | Greenwich, the free half |
| 4 | The South Bank without the queue |
Book these before you go
- Book a free Sky Garden slot , released Monday mornings and gone within hours
- Skip the line at the Tower if it’s still on the list
- Book a Thames river cruise to Greenwich instead of the DLR
- Compare Westminster and South Bank hotel rates
Day 1: Bloomsbury’s free museums, done right
Start at the British Museum, but skip straight past the Rosetta Stone crush to the quieter Sutton Hoo and Asia rooms while the queue outside is still forming; general admission has always been free, though a timed slot booked two or more weeks ahead is worth it for weekends and this autumn, when the Bayeux Tapestry arrives on its first-ever loan outside France. Walk ten minutes to Sir John Soane’s Museum on Lincoln’s Inn Fields for the afternoon, a free house-museum stacked with Egyptian sarcophagi and Piranesi drawings that never runs a ticketed queue, just a short wait if the 90-person capacity fills up. Finish at the Wellcome Collection on Euston Road, also free, open until 8pm on Thursdays if the day needs stretching. All three sit within a 15-minute walk of each other and cost nothing beyond lunch.
Day 2: The Square Mile, London’s oldest secret
Head into the City of London, the original walled square mile with its own police force and just 8,600 residents against a weekday workforce topping 600,000, which is why it empties out fast after office hours and on weekends. Find Postman’s Park behind King Edward Street, a small garden holding 54 hand-painted ceramic tablets memorializing ordinary Londoners who died saving strangers, then wander Leadenhall Market’s Victorian glass-and-iron arcade, used as Diagon Alley’s exterior in the Harry Potter films and nearly empty outside weekday lunch hours. Book a Sky Garden slot for sunset if the timing lines up, free entry but released every Monday morning for the next three weeks and gone within hours; bring photo ID matching the booking. The Tower of London sits a short walk east if the big-ticket sight is still on the list.
Day 3: Greenwich, the free half
Take the DLR to Greenwich, 20-25 minutes from central London, or book a Thames cruise if the boat matters more than the time saved. The National Maritime Museum and Greenwich Park cost nothing to enter, and the Old Royal Naval College’s Painted Hall, sometimes called Britain’s Sistine Chapel, is worth the roughly GBP 17.50-19 general admission or the GBP 5 First Sunday rate if the trip lands on one. Skip the Cutty Sark’s paid deck tour unless the ship itself is the point; the free half of Greenwich already fills an afternoon.
Day 4: The South Bank without the queue
Walk the Thames from the London Eye toward Tower Bridge and let Tate Modern anchor the middle of the day, free permanent collection, no booking needed. Borough Market gets its lunch crowd from Thursday through Saturday, so a Wednesday visit means actual elbow room at the cheese and charcuterie stalls. Duck into Southwark Cathedral, older than Westminster Abbey and rarely mentioned alongside it, free to enter, before the South Bank’s evening crowd builds along the river path.
Four days is enough to string these together without doubling back across the city; Bloomsbury, the City, Greenwich, and the South Bank each sit on their own Tube or DLR line. Westminster’s cheapest hidden ticket and Kensington’s museum mile are the next two additions worth making on a longer trip.
