In one day you can see Westminster, Buckingham Palace, Trafalgar Square, the South Bank, St Paul's Cathedral and Tower Bridge by walking one continuous line through the centre, using the Tube only to arrive and to get home. You will see most places from the outside and choose just one or two to go inside.
The mistake most one-day visitors make is trying to visit everything properly. The Tower of London alone needs at least three hours, and a morning in the British Museum can easily become a whole day. A realistic single day in London is a walk: a chain of famous places that happen to sit close together, linked by the river and the royal parks.
This plan follows that chain from west to east, about 8 to 10 kilometres on foot with plenty of stops. It works best from Monday to Saturday, and it suits first-time visitors, people on a stopover and anyone who wants to see the classic sights without spending the day underground.

09:00: Westminster before the tour groups arrive
Start at Westminster station and walk out onto Westminster Bridge. From the middle of the bridge you get the classic view of the Elizabeth Tower, which houses the bell known as Big Ben, and the long river front of the Houses of Parliament. Early in the morning the pavements are still manageable; by late morning they are crowded. Our page on Big Ben and the Elizabeth Tower explains what you are looking at.
Walk back to Parliament Square. Westminster Abbey stands on its south side, where kings and queens have been crowned for nearly a thousand years. Going inside takes a good part of the morning and costs money, so on a one-day plan we would admire it from the outside and save it for a future trip. If the Abbey is your one priority, make it your first stop instead and see our Westminster Abbey visitor guide for tickets and times. Remember that Sundays are for worship there, not sightseeing.
Parliament itself is open to overseas visitors in two ways. Watching debates from the public galleries of the Commons and the Lords is free, and paid guided tours (£40 for an adult in advance) run on Saturdays all year and from Monday to Saturday when Parliament is in recess. Both take time you may not have today. For more on the area, from Downing Street to the government buildings of Whitehall, read our guide to the Westminster neighbourhood.
10:15: through St James's Park to the palace
From Parliament Square, walk along Great George Street and into St James's Park. Follow the lake west. It is one of the prettiest walks in central London, with views back towards Whitehall and forward to Buckingham Palace, and it takes around 15 to 20 minutes at a gentle pace. Our guide to St James's Park and Green Park points out what to look for on the way.
11:00: Buckingham Palace and the Changing the Guard
Whether you see soldiers at the palace depends on the day. In September 2026 the Guard Change at Buckingham Palace was scheduled at 11:00 on Mondays, Wednesdays and Fridays, although not on every one of those days (there was none listed for Friday 25 September). A Sunday parade takes place at 10:00 on some Sundays. The dates change every month, so check the official Changing the Guard calendar the evening before.
If the ceremony is on, arrive well before 11:00 and stand at the railings, on the Victoria Memorial steps, or along The Mall where the soldiers march. Our guide to watching the Changing of the Guard compares the viewing spots. If it is not on, you lose nothing: the palace front is worth ten minutes, and you move on sooner.
In summer you can also go inside. The State Rooms open from 9 July to 27 September 2026 (closed on Tuesdays and Wednesdays in September), from £33 for an adult booked in advance or £37 on the day. On a one-day trip, though, a two-hour palace visit leaves little time for the rest of the route. See our Buckingham Palace guide if you want to plan around it.
No guard change means a head start on the crowds. On days without the ceremony, skip the wait at the palace and use the extra hour for the National Gallery or a longer lunch. Going straight down The Mall to Trafalgar Square takes about 15 minutes.
12:00: The Mall, Trafalgar Square and one hour of paintings
Walk east along The Mall, the broad red road from the palace, and through Admiralty Arch to Trafalgar Square. Nelson's Column stands in the middle. The Fourth Plinth, in the north-west corner, displays a series of commissioned artworks; since 10 September 2026 it has held Lady in Blue by Tschabalala Self.
The National Gallery fills the north side of the square. It is free, open daily from 10:00 to 18:00 (until 21:00 on Fridays), and you can simply walk in, although an optional free ticket gives faster entry. The main free entrance is now the Sainsbury Wing. One focused hour is enough to see a handful of masterpieces, and our National Gallery guide suggests which rooms to aim for. Some rooms are closed during building work, so a favourite painting may have moved.
13:15: lunch in Covent Garden
Covent Garden is five to ten minutes' walk north-east of Trafalgar Square. The old market building, the street performers in the piazza and the lanes around it make it a good lunch stop, with everything from sandwich shops to proper restaurants. Prices around the piazza are higher than in the side streets. Our Covent Garden area guide covers where to eat without paying tourist-trap prices.
14:30: crossing Waterloo Bridge to the South Bank
From Covent Garden, walk down to the Strand and out onto Waterloo Bridge. We rate this as one of the best free views in the city: Westminster and the London Eye to the west, St Paul's and the City towers to the east. Take your photos from the bridge, then go down the steps on the far side to the river path.
Now walk east along the South Bank riverside. You pass the Southbank Centre, the National Theatre, the second-hand book stalls under the bridge and Gabriel's Wharf. This stretch is flat, traffic-free and full of places to sit.
If you want to ride the London Eye, you will pass it only if you start this section at Westminster Bridge instead. One rotation takes 30 minutes, standard tickets start at £29 online and cost £39 walk-up, and online prices vary with demand. On a one-day plan we would leave it out: add queuing and security, and it costs you an hour or more of the day.
15:30: Tate Modern and the Millennium Bridge
About 20 minutes along the river you reach Tate Modern, the former power station with the tall brick chimney. Entry to the collection is free, and it is open until 18:00 from Sunday to Thursday and until 21:00 on Fridays and Saturdays. Even if modern art is not your thing, walk into the Turbine Hall and take the lift to an upper level for the view. Our Tate Modern guide has more.
Directly outside, the Millennium Bridge (a footbridge) crosses the Thames straight towards the dome of St Paul's. It is one of the best framed views in London.
16:30: St Paul's Cathedral, inside or out
The cathedral is open for sightseeing Monday to Saturday. An adult ticket costs £27 (£29.70 with a donation), which includes the cathedral floor, the crypt and the Dome Galleries, with a multimedia guide. Climbing to the galleries takes time and energy, so check the last entry time on the cathedral's website before you commit this late in the day. On a Sunday there is no sightseeing, but the outside and the steps are still a fine stop. See our St Paul's Cathedral guide for tickets and services.
Swap the order if St Paul's matters more than the palace. If you want the Dome Galleries rather than the guard, start at St Paul's when it opens, walk west along the South Bank, and finish at Westminster at sunset. The route works in both directions.
17:30: the Tower of London and Tower Bridge at the end of the day
From St Paul's, it is about 30 minutes on foot to the Tower through the City of London, or a short Tube ride from St Paul's to Tower Hill with a change (and your legs will thank you). Either way, you arrive as the office crowds thin out.
By this time the Tower of London itself is closing: last entry is 16:30 and the gates shut at 17:30. In any case the Tower recommends at least three hours, and an adult ticket costs £37. See it from outside instead: walk around the moat, then along the river path below the walls to Tower Bridge.
Tower Bridge's walkways and engine rooms open daily from 09:30, and the official site has given two different closing times in September 2026, so check the bridge's visitor page if you hope to go inside this late. On this route you will usually see the bridge from the outside. Walk across it for the views up and down the river. If you are lucky, the bridge may lift for a passing ship; the official bridge lift schedule lists the times. Our Tower Bridge guide explains what is inside if you come back another day.
Getting around: when the Tube earns its place
You need public transport twice: to reach Westminster in the morning and to get back to your hotel in the evening. Use a contactless card, a phone or an Oyster card. Adult pay as you go fares in Zones 1-2 are capped at £8.90 a day, and a Zone 1 journey costs £3.10 at peak times and £3.00 off-peak. Peak hours are 06:30–09:30 and 16:00–19:00 on weekdays.
If your feet give up, buses are a pleasant alternative, costing £1.75 a journey (rising to £1.85 on 1 November 2026), with free changes within an hour. Our guide to walking versus the Tube in central London shows which hops are quicker on foot.
Adjusting the plan for rain, Sundays and children
On a wet day, keep the shape of the route but spend longer indoors: the National Gallery and Tate Modern are both free and directly on the way. Our list of things to do in London when it rains has more ideas.
On a Sunday, Westminster Abbey and St Paul's are closed for sightseeing, so this is the day to go into the free galleries instead. Shops open later, and large stores can trade for only six hours between 10:00 and 18:00.
With children, shorten the walk. Drop the National Gallery and Tate Modern, keep St James's Park (the pelicans and playground help), and consider the London Eye, which children usually remember longer than a cathedral. Children aged 5 to 10 travel free on the Tube with a fare-paying adult.
If you have a second day, our two-day weekend plan goes inside the Tower and adds a market and a West End show.
Frequently asked questions
Is one day enough to see London?
One day is enough to see the main landmarks from outside and visit one or two of them properly. It is not enough for the big museums or the Tower of London in any depth. If you can, allow three days for a first visit.
What is the best route for one day in London on foot?
Follow the river from west to east: Westminster, St James's Park, Buckingham Palace, Trafalgar Square, Covent Garden, the South Bank, Tate Modern, St Paul's Cathedral and the Tower. It is about 8 to 10 kilometres with stops, and you need the Tube only at the start and end.
Can I see the Changing of the Guard on any day?
No. In September 2026 the ceremony at Buckingham Palace was scheduled at 11:00 on Mondays, Wednesdays and Fridays, with some exceptions, and a parade took place on some Sundays. Check the Household Division's calendar before you plan your day around it.
Should I visit the Tower of London if I only have one day?
Only if it is the one thing you most want to see. The Tower recommends at least three hours, and an adult ticket costs £37, so it takes about a third of your day. Most one-day visitors are better off seeing it from outside and crossing Tower Bridge.
How much does a day of sightseeing in London cost?
This route can cost very little: transport is capped at £8.90 for adults in Zones 1-2, and the National Gallery and Tate Modern are free. Adding St Paul's (£27) or the London Eye (from £29 online) raises the cost, and lunch in Covent Garden varies widely.
