A week is enough to see London properly without racing: the classic sights in the first three days, then the Natural History Museum and Hyde Park, Greenwich by boat, St Paul's with the City and Borough Market, and a day trip to Windsor Castle. Each day stays in one area and is planned on foot.
An easy first day outdoors, good for jet lag: a morning walk in St James's Park, the Changing of the Guard at 11:00, the Abbey, Big Ben and the river at dusk.
Wander lakeside paths past pelicans and ducks, with Buckingham Palace rising at the far end of the water. Green calm and royal grandeur sit side by side in one easy stroll.
Stand at the railings as red-tunicked guards march in step, bearskin hats high, with a band playing and the stamp of boots carrying across the forecourt. It's full-dress pageantry you feel as much as you see.
Walk the same stone floors where 40 monarchs were crowned and trace royal tombs and poets' memorials under soaring Gothic vaults. Step inside for a slow hour of history that the rain can't spoil.
Tilt your head back beneath the clock tower at Westminster and wait for the Great Bell to strike. Its chimes roll out over the Palace of Westminster, and you'll feel each hour in your chest.
Rise slowly above the Thames in a glass capsule and watch London spread out in every direction. Pick the champagne option and toast the view as the light fades over the river.
The oldest part of London and the river: the Tower and the Crown Jewels in the morning, lunch nearby, Tower Bridge, then Tate Modern and the Millennium Bridge with St Paul's ahead of you.
Trace two rings of walls and a moat around a fortress begun in 1066, then stand beneath the White Tower that gives it its name. Then see the Crown Jewels glittering behind glass.
Stand on the bridge above the Thames and watch the river slide past the Tower of London's walls. Gothic towers and Victorian steel make every crossing feel like a small adventure.
Step inside a former power station on the Thames and wander through the UK's national collection of modern and contemporary art. Give yourself a long afternoon, because the rooms reward slow, curious looking.
Cross the steel span linking Bankside and the City, with the Thames wide and glinting beneath your feet. Pause mid-bridge and let the river light change around you.
Free world-class museums and the West End: the British Museum's highlights, lunch in Covent Garden, the National Gallery and Trafalgar Square.
Step into eight million artefacts that trace human history from its earliest beginnings to today. Lose track of the hours in galleries of art and culture in Bloomsbury.
The covered 1830s market hall holds shops, craft stalls and cafés, with the London Transport Museum next door to stretch the day out.
Step off Trafalgar Square into rooms of paintings spanning the mid-13th century to 1900, and let the canvases hold your attention for as long as you like. Guided tours bring the stories behind the works to life.
Stand at the foot of Nelson's Column and watch the fountains throw spray across the stone while pigeons wheel overhead. Then climb the National Gallery steps, where the whole square opens out below you.
One big museum in the morning, a wander through Harrods' food halls in Knightsbridge, then Hyde Park and the Serpentine. The Tube is at the museum's door.
Come face to face with a vast range of natural history specimens, from towering skeletons to tiny preserved creatures. Lose yourself for hours in the grand halls on Cromwell Road, where something new turns up around every corner.
Browse the food halls, pick up something you didn't plan to buy, then sit down for a cream tea. Whole floors of shopping make a rainy London afternoon disappear.
Wander the shores of the Serpentine in a 350-acre royal park where the trees soften the city's noise. Follow the green chain toward Kensington Palace or Buckingham Palace at your own pace.
A day out by boat: the Uber Boat from Westminster or the London Eye pier to Greenwich (about an hour), the Cutty Sark, the Painted Hall, the free Maritime Museum and the view from Greenwich Park.
Step aboard a 19th-century tea clipper built for speed and wander her decks in Greenwich, beside the Thames. Stand beside one of the fastest ships of her kind and picture the race across the seas.
Painter James Thornhill worked on this ceiling for nearly 20 years. Painted columns and steps trick the eye into a far grander room. Most people heading to the Cutty Sark walk right past it.
Trace Britain's seafaring past through galleries full of ships, charts and sailors' stories in Greenwich. General entry is free, so you can wander as long as the sea's stories hold your attention.
Stroll 74 hectares of former hunting park, then climb to the hilltop Royal Observatory and straddle the Prime Meridian. Views sweep over the Thames, the Isle of Dogs and the City.
Inside St Paul's Cathedral, lunch under the Victorian roof of Leadenhall Market, a free view from the Sky Garden, then across London Bridge to Borough Market.
Stand beneath Wren's great dome, finished in 1710, and feel the hush of a working cathedral on Ludgate Hill. Trace centuries of London history, from Great Fire ashes to the spot where St Paul's Cross once stood.
Step off Gracechurch Street into a covered market where centuries of trade meet the buzz of City lunch breaks. Browse the shops and eateries, then linger under cover, rain or shine.
Rise to three floors of planted terraces and glass walls, with London's rooftops spread out far below. Linger among the greenery and watch the city stretch out from 160 metres up.
Wander the 1850s market halls of Borough Market, where cheese wheels, fresh bread and spiced oils crowd the stalls. Taste your way along the counters and let the smells decide where you stop next.
The King's weekend home, 35 minutes by train from Paddington (change at Slough) or Waterloo: the State Apartments, St George's Chapel and the town by the river.
Walk the stone ramparts above the Thames and step into state rooms where generations of monarchs have entertained and dressed for ceremony. Then wander the old streets of Windsor town before the easy train ride back to London.
The big museums, the parks and the bridges are free. These need a ticket or a timed slot; book online for the best price.
