London in 3 Days: Westminster, the City & the West End
Who this is for: First-time visitors with ~3 full days who want the royal-and-parliamentary core, the historic City and the museums — grouped so each day stays in one part of town instead of criss-crossing a very large city.
Timing assumptions: Assumes a central base (West End, South Bank, King’s Cross or Kensington), moving by Tube and on foot with contactless tap-in, arrival/departure handled separately. Day 1 is Westminster and the South Bank; Day 2 is the City and the East End; Day 3 is museums and the West End. Sunday is the day to watch: the Abbey and St Paul’s take no sightseers then, so shuffle the days rather than fight the calendar.
Getting around: Don’t buy tickets — tap a contactless bank card or phone at the gates for the Tube, buses and the Elizabeth line, and daily charges cap automatically (Zones 1–2 around £8.90; buses a flat £1.75 with the Hopper fare giving free changes within an hour). Each traveler taps their own card, every time. The TfL Go and Citymapper apps handle routing; Citymapper is honest about when walking beats the Tube — central districts sit far closer together than the Tube map implies. Santander Cycles (the docked bike-share) covers the parks and the riverside well. From Heathrow, the Elizabeth line (~£15.50, ~35 min) beats the Heathrow Express on value for most travelers, and the Piccadilly line (£5.90, ~55 min) beats both on price; from Gatwick, Thameslink trains (~£12–15) undercut the Gatwick Express. Black cabs and Uber both work well but London traffic makes them slow crosstown by day.
When to go: May–September is the sweet spot for weather: daytime highs of roughly 17–25°C, long evenings and every park and market at full tilt — with June–August the most crowded and expensive stretch. Buckingham Palace’s State Rooms only open to visitors in that summer window. September–October trades a little warmth for thinner crowds. December is cold (8–10°C), dark by 4pm and expensive, but the Christmas lights and markets are genuinely worth it; January–February are the cheapest, quietest months. There is no dry season — light rain can show up any month, so pack a layer and keep museum days in reserve.
When to go — month by month
Average daytime high (bars) and rainy days per month, from 5-year climate normals. Greener months are the most comfortable to visit.
Best months to visit: May–Sep
Daylight by month
Hours of daylight through the year in London — it swings from about 7h 37m in midwinter to 16h 22m at midsummer, which decides how many stops realistically fit in a day.
Day 1 — Westminster & the South Bank
Anchor in the monarchy-and-parliament core, then cross the river for London’s best walk.
- ~1.8hWestminster Abbey timed entryThe coronation church, a thousand years of royal history and Poets’ Corner. Book a timed ticket online (~£30, cheaper than the door) — and not on a Sunday, when it’s open for worship only.
- ~30mParliament Square & Big Ben walk-upThe Elizabeth Tower, the Houses of Parliament and Churchill’s statue — all exterior views, all free, best photographed from the west end of Westminster Bridge.
- ~1.3hSt James’s Park & Buckingham Palace walk-upWalk the park’s lake to the palace forecourt. If it’s a Changing of the Guard day (it is not daily — check the schedule), arrive 45 minutes early for a spot at the railings.
- ~2hSouth Bank riverside walk to Borough Market walk-upCross Westminster Bridge and walk east past the London Eye, the National Theatre and Tate Modern to Borough Market (closed Mondays). Ride the Eye (~£29+ online) only if a slow 30-minute rotation appeals more than the free views along the way.
- Route logic:
- A single west-to-east arc: church, parliament, palace, then across the river and downstream with the current — no backtracking.
- Getting between stops:
- Entirely walkable — roughly 5km end to end at a stroll. Westminster and Waterloo Tube stations bracket the route if feet give out.
- Meals:
- Lunch: St James’s or grab-and-go in the park. Dinner: Borough Market’s restaurants and pubs, or back toward the South Bank’s riverside terraces.
- Rain / limited mobility:
- Rainy day: swap the riverside walk for Tate Modern’s free galleries and the Churchill War Rooms (book ahead). Sunday: the Abbey is worship-only — swap Day 1 and Day 3, or visit the (free) museums instead.
Day 2 — The City, the Tower & the East End
Trace London’s oldest square mile from cathedral to fortress, then finish in its liveliest modern quarter.
- ~1.5hSt Paul’s Cathedral timed entryWren’s dome, the Whispering Gallery climb and the crypt (~£27 online). Sightseeing runs Monday–Saturday; Sundays are for services only.
- ~45mWalk the City to the Tower walk-upCut through the ancient-meets-glass streets — Leadenhall Market’s Victorian arcade makes the best route — to emerge at the Tower moat.
- ~2.5hTower of London timed entryThe Crown Jewels, the ravens and a free Yeoman Warder tour (they leave every 30 minutes and are genuinely funny). Book the first morning slot if you can — the Jewels queue only grows. ~£35–37 online.
- ~2hTower Bridge, then Shoreditch (evening) walk-upWalk across the bridge for the classic view, then head north to Shoreditch and Brick Lane for street art, vintage shops and dinner.
- Route logic:
- Chronological London: the 300-year-old cathedral, the 950-year-old fortress, then the neighbourhood where the city is being reinvented — one eastward line.
- Getting between stops:
- St Paul’s to the Tower is a 20–25 minute walk; the Tower to Shoreditch is a short bus or Overground hop, or a 25-minute walk up through Spitalfields.
- Meals:
- Lunch: Leadenhall Market or a City pub. Dinner: Shoreditch or Brick Lane — curry houses, bagel shops and some of London’s best small restaurants.
- Rain / limited mobility:
- On a Sunday this day works better than Day 1: skip St Paul’s interior, start with Columbia Road Flower Market (Sunday mornings only) and Brick Lane’s market, then do the Tower in the afternoon.
Day 3 — Museums, Covent Garden & a West End show
Spend the day in world-class free museums, then give the evening to the West End.
- ~2.5hBritish Museum (or the South Kensington museums) walk-upThe Rosetta Stone, the Parthenon sculptures and the Great Court — free, no ticket needed for general admission. Families may prefer South Kensington, where the Natural History, Science and V&A museums share one street, all free.
- ~1.5hCovent Garden piazza & Neal’s Yard walk-upStreet performers, the covered market and the candy-coloured courtyard of Neal’s Yard — the best aimless-wandering hour in central London.
- ~1.5hSoho & Chinatown walk-upDrift west through Seven Dials into Soho’s lanes and Chinatown’s gates — this is pre-theatre dinner territory, so eat early (5–6:30pm) like the locals with tickets do.
- ~2.8hA West End show book aheadBook hit shows well ahead online; otherwise the official TKTS booth on Leicester Square sells legitimate same-day discounts, and many theatres run day-seat lotteries.
- Route logic:
- Museum energy in the morning while you’re fresh, low-effort wandering in the afternoon, and a seated show to end the trip — effort declining as the day goes on.
- Getting between stops:
- Bloomsbury to Covent Garden is a 15-minute walk; everything after that is within the same square kilometre. If you chose South Kensington, the Piccadilly line runs straight to Covent Garden.
- Meals:
- Lunch: the museum café or Bloomsbury/South Ken around it. Dinner: pre-theatre menus in Soho or Covent Garden — many good restaurants price a fixed early menu exactly for showgoers.
- Rain / limited mobility:
- Saturday: swap the morning for Portobello Road Market in Notting Hill (its main antiques day). Prefer views to theatre: book the free Sky Garden (advance slots online) for sunset instead. With kids: South Kensington’s museums, then an earlier, family-friendly show.
⚠︎ Before you book
- The Tower of London, Westminster Abbey and St Paul’s all sell timed tickets online for less than the walk-up price — book all three before you fly, especially June–August.
- Sundays reshape the plan: the Abbey and St Paul’s take no sightseers (worship only), Borough Market is closed Mondays, and Changing of the Guard runs only on set days — check the schedules before fixing which day is which.
- West End hits and the Warner Bros. Studio Tour (Harry Potter, out at Watford) sell out well ahead — the studio tour has no door sales at all.
Weather & mobility: Rain is a rescheduling tool, not a ruin: every day above has a museum-heavy wet-weather swap, and the free national museums absorb whole afternoons. Distances within each day are walkable but add up to 6–8km — comfortable shoes matter more than in most cities. Step-free access is patchy on the old Tube network (the Elizabeth line and buses are the reliable accessible options); the Abbey, St Paul’s floor and the museums all manage wheelchairs well, though St Paul’s dome galleries and some Tower interiors are stairs-only.
Budget: London is expensive to sleep in, cheap to get around, and free to see more of than any comparable city. Approximate (verify current prices): contactless Tube cap Zones 1–2 ~£8.90/day, bus fare £1.75; a supermarket meal deal £4–5; a pub main £15–22; a casual dinner £20–35; a mid-range restaurant dinner with a drink £40–60; a pint £6–7.50 centrally. General admission to the national museums is free. Big paid sights: Tower of London ~£35–37, Westminster Abbey ~£30, St Paul’s ~£27, London Eye from ~£29 online — all cheaper booked in advance. June–August and December push hotel prices well above baseline; January–February run cheapest.
Optional swaps
- Traveling in winter? Daylight ends around 4pm in December–January — front-load outdoor walking into the morning, push museums to the afternoon, and let the Christmas lights carry the evenings.
- Visiting between early July and late September? Buckingham Palace’s State Rooms are open (summer only, book ahead) — they can replace the Day 3 morning museum for monarchy-minded travelers.
- Want one day out of town? Windsor Castle is the realistic half-day trip (~1 hour each way); give it Day 3’s morning and keep the evening show.
What this plan intentionally leaves out
- Stonehenge & Bath as a day trip: The combined coach day runs 10+ hours with most of it on a motorway. Worth it only if the stones are a personal priority — it costs a full London day.
- Warner Bros. Studio Tour (Harry Potter) by default: It’s a half-day-plus commitment out at Watford and sells only advance tickets, often weeks out. Included as a deliberate pre-booked choice, never a default — spontaneous visits are impossible.
- Greenwich on a first 3-day pass: Genuinely great (the Observatory, the meridian, the Cutty Sark) but a half-day round trip downriver; it earns its place on a 4th day or a return visit.
- Buying a bundled sightseeing pass without arithmetic: London’s best museums are free, so attraction passes only pay off on an unusually paid-ticket-heavy plan — price your actual list before assuming a pass saves money.
Planning notes & sources
The day-by-day routing — a Westminster-and-river day, a City-and-East-End day, and a museums-and-theatre day — and the time estimates here are our own, built to keep each day inside one part of a very large city. Because fares, ticket prices, ceremony schedules and opening days shift, confirm current details with Visit London, TfL and each sight’s official site before you set out — especially the Sunday worship closures and the Changing of the Guard calendar, which reshape which day is which.
