Most "itineraries" are a list of dots on a map. These are sequenced by the clock — what's open when, what needs a timed ticket, where you'll actually eat, and which afternoon to bail out of the city for Windsor. Built for the planner who'd rather decide than scroll.
London isn't spread out — it's a dozen villages wired together by a Tube that takes longer than you think. The single biggest lever is order: do outdoor landmarks before the 10:00 crowds, hit ticketed sights on a timed slot, use the free museums for the dead middle of the day, and save neighbourhoods for the loose afternoon. Every plan below is built on that rhythm.
Read Practical & transport first. The two most expensive beginner mistakes are buying paper Tube tickets (use contactless — daily cap about £8.90 in 2026, verify on the official TfL site) and walking up to the Tower of London with no timed ticket. Both are avoidable and both cost real money.
Tight but doable. This assumes you arrive with a full first day and leave on the morning of day four. Two timed tickets, one paid icon, and the rest is free or walkable.
08:30–10:00 · Outdoor landmarks. Start at Westminster — Big Ben and the Houses of Parliament look best empty at 08:30, and you beat the coach tours. Walk across Westminster Bridge for the postcard shot of the Houses of Parliament.
10:00–12:00 · Ticketed sight. Tower of London — book ahead, not free (about £33 in 2026, verify on the official site). Timed entry walks straight in; the walk-up queue hits 45 minutes by 11:00. See the Crown Jewels before noon.
12:30–14:00 · Free + lunch. Borough Market (Southwark) — free to wander, £6–£12 for lunch from the stalls. Best cheap, genuinely good food in the tourist core.
14:30–16:30 · Neighbourhood. Walk the South Bank to the London Eye. London Eye is paid (~£29–£44 in 2026, verify); if the queue is long, take the river cruise instead (below) — same skyline, half the wait.
10:00–13:00 · Free museum. British Museum (free, book the timed entry in summer peaks) or Natural History Museum (always free, always crowded — go early). Free, but the special exhibitions cost.
13:00–14:30 · Lunch. Covent Garden — touristy but fun;Eat at the covered market for £8–£15. Then a free wander through the piazza street performers.
15:00–17:00 · Paid icon or walk. St Paul's Cathedral (paid, ~£25 in 2026) or just walk the City's alleyways for free. Decide by energy, not FOMO.
19:30 · West End. A show is the one splurge worth it. See the tours page for Mamma Mia / Lion King tickets.
Option A (recommended): a guided day trip to Windsor or Oxford — you'll see a castle or a university town without the tube-battle. book ahead
Option B: stay in town — Camden Market (free to browse, £10 lunch) + Regent's Park, or Greenwich (free observatory hill view, paid Cutty Sark).
Where to eat on this plan: Borough Market (day 1), Covent Garden market (day 2), and a neighbourhood market on day 3. Skip the £20 "tourist plate" on the main drag — two streets back, prices halve.
Days 1–3 follow the 3-day plan above. Days 4–5 are where London opens up: a proper escape from the city, and a neighbourhood that isn't on every list.
Pick one and commit: Stonehenge + Bath by tour (no car, no stress) or Windsor by train (fast, you control the clock). A guided tour is worth it here — the coach math beats DIY once you add trains + entry + Stonehenge's middle-of-nowhere location. Full comparison on the day trips page.
Morning: Notting Hill + Portobello Road (Saturday market only; free to browse). Or Columbia Road flower market on Sunday.
Afternoon: A walking tour of Westminster or the 30-top-sights loop — better than a bus when you've already seen the skyline. paid, ~£20–£35
Evening: Sky Garden or The Shard for the lit-up skyline (Sky Garden is free but books out weeks ahead; Shard is paid).
The day trip is the upgrade that earns its place — five days with zero escape from central London feels like a longer three days. Spend the day-trip money on a tour, not on squeezing in another museum.
Seven days is the sweet spot: the 3-day core, two different day trips, a West End night, and real time in markets and museums without the "I saw it but I was running" feeling.
Days 1–3: the 3-day plan (Westminster → Tower → South Bank; museums + show; one intro day trip).
Day 4: Oxford or Bath by train — university town or Roman baths, your call.
Day 5: Harry Potter Studio (it's a half-day, coach package from central London; book the timed slot early — it sells out) OR Windsor + Stonehenge by tour.
Day 6: Neighbourhoods — Camden, Shoreditch street art, Greenwich. All free to explore; pay only for specific entries.
Day 7: Anything you missed + a Thames cruise at golden hour. Loosely.

Where to eat across a week: keep the pattern — market lunches (Borough, Camden, Portobello), one West End dinner, and a neighbourhood spot (Brixton, Hackney) for the "real London" meal. The practical page has the 2026 transport math that keeps all of this cheap to move between.
The four things above that are genuinely worth pre-booking — hand-picked from GetYourGuide with real review counts. Pre-booking beats the gate queue every time.
The classic open-top loop with a river cruise extra. Good on day one to get your bearings — ride the full loop before you commit to walking.
The slow turn over the Thames. Fast-track skips the worst of the queue on sunny days — worth it in July and August.
Pre-booked timed entry walks straight in; the single most queue-prone sight in the 3-day plan.
The coach does the driving and the entries. The easiest way to add a day trip to the 3- or 5-day plan without renting a car.
