Paris for the Day by Eurostar

Published 18 September 2026 · By the Guide to London editorial team · Editor: Terje Moy

A Paris day trip from London is possible, and on the right date it is genuinely worth doing: an early train out and a late train back leave you roughly nine hours on the ground, enough for one big museum, one long walk and a proper lunch. Do not attempt it on a Tuesday, when the Louvre is shut, and do not attempt it at all if the fare on your date is close to the price of a night in a hotel.

The maths is what decides this trip. French clocks are an hour in front, so the morning costs you sixty minutes that you win back at night. Check-in at the two stations swallows another two and a half hours between them. Everything left over is your day, and how much is left depends entirely on which pair of trains you book.

This page is about that day: which departures make it work, what fits between them, how to move around Paris, where the hours go and how to be sure of the last train. The service itself, including fares, classes, luggage and the border, is covered in our guide to the Eurostar from London to Paris.

Is a day in Paris worth the fare?

Our view: yes for a second or third visit to London, when you have already seen the obvious things here and want a day that feels like a different country. No for a first trip of four or five days, because the hours you spend in a queue at two stations would buy you the Tower, the British Museum and an evening walk along the Thames instead. Our guide to how many days to spend in London sets out what you would be giving up.

Price decides the rest. Two of the cheapest Standard fares come to £78 per person, so £156 for a couple before you have bought a Métro ticket. On a weekend, in school holidays or at short notice the same pair of trains can cost several times that, and at some point a night in Paris with an unhurried evening costs less than the rushed version. Compare the fare on your date against the nearest British alternatives before you commit; our list of the cheapest day trips from London is a useful reference point, and Canterbury gives you a cathedral city and a shorter day for a fraction of the money.

Which departures make the day possible

Eurostar runs roughly hourly through the middle of the day, but only the first two or three departures leave you a real day, and only the last two or three let you use it. Times move with the date, so treat the table below as the shape of a Tuesday in September 2026 rather than a timetable to book from. Check your own date on Eurostar's London to Paris page.

Read the last column carefully. The 08:01 looks civilised and gives you barely six usable hours, of which one will go on lunch and one on the Métro. The 06:01 is the only departure that turns this into a full day, and it comes at a price: you need to be inside the terminal before 05:00, which is before the Underground starts running.

That is the real argument for sleeping near the station the night before. A hotel within walking distance of the platform removes a taxi booked for 04:30 and the worry that goes with it. We have a whole guide to hotels within reach of the platform, and what the King's Cross district is like once the commuters have gone. If you have already checked out of a hotel elsewhere, leave your case behind rather than dragging it across the Channel and back; the storage options are in our round-up of London luggage lockers.

Tickets and the border, in short

Book as far ahead as you can, because Eurostar fares rise with demand, and enter your passport details in the app as soon as you have booked. You need a valid passport in both directions, and if your nationality requires a UK Electronic Travel Authorisation, it must still be valid when you come back, because a day in Paris counts as a new arrival in Britain.

Everything else belongs on the page that owns it: the biometric registration the EU now runs at St Pancras, why the British and European permissions are easy to confuse, how long the checks take and what a missed train costs are all set out on our Eurostar service guide, with the British paperwork explained in who needs an ETA to enter Britain. Read both before you book, not on the morning.

Getting around Paris on the day

Gare du Nord sits on Métro lines 4 and 5 and on RER lines B and D, so almost everywhere a visitor wants to go is a single change away at most. That is the main practical advantage of this trip over a flight: you step off the train and you are already in the city.

The fares were simplified in 2025, and the card tickets that older guidebooks describe are no longer sold. A single Métro, RER or suburban train journey now costs €2.55 anywhere in the Île-de-France region, bought in the Île-de-France Mobilités app or loaded onto a rechargeable Navigo Easy card. Airport services are excluded and priced separately, which does not affect a day in the city. Buses and trams take a different ticket from the Métro one, so if your plan mixes the two, buy the day pass instead.

That day pass, the Navigo Jour, costs €12.30 and covers every zone and every mode except the airport services, from the first service of the morning to the end of the night buses. Five single journeys already cost €12.75, and on a day trip you will make five without trying: into the centre, one hop at lunchtime, one to the afternoon sight, one to dinner, one back to the station.

Note what that means for the gateline. Île-de-France Mobilités sells its tickets through the app or onto a Navigo Easy pass, not by tapping an ordinary bank card at the barrier, so the habit you pick up on the Tube will not get you through a Paris turnstile. Sort out a ticket first. Your phone will be roaming, too, unless your plan covers France: our guide to SIM cards and eSIMs explains how to avoid a surprise, and our guide to money, cards and contactless covers the foreign transaction fees that turn a €12.30 pass into something more.

What actually fits between the two trains

One major museum and one long walk. That is the honest limit of a nine-hour day, and trying to add a third thing is how people end up seeing the Eiffel Tower from the window of a taxi they should not have taken.

The plan that works for most first-time visitors starts underground from Gare du Nord towards the centre, gives the late morning and early afternoon to the Louvre on a pre-booked time slot, and then walks. West through the Tuileries to Place de la Concorde, along the river towards the Eiffel Tower, or across to the Left Bank and Saint-Germain. Aim to be looking at the tower from the Trocadéro side in the late afternoon, then take the Métro back with time in hand.

On a second visit, swap the centre for Montmartre. The hill around the Sacré-Cœur is closer to Gare du Nord than anything in the middle of the city, which takes the pressure off the end of the day, and the basilica costs nothing to enter.

The Louvre on a day trip

The Louvre is closed on Tuesdays, which rules out the whole plan if your date falls on one. It opens 09:00 to 18:00 on Monday, Thursday, Saturday and Sunday, and stays open until 21:00 on Wednesday and Friday, with last entry an hour before closing. For visitors from outside the European Economic Area, which includes UK residents, an adult ticket is €32; EEA residents and citizens pay €22, and under-18s go free. Book a time slot even if you qualify for free entry, and read the Louvre hours and admission page for the current rules.

One detail matters more on a day trip than it would on a holiday: once you leave the museum, your ticket is finished. There is no stepping out for lunch and coming back, so eat first or accept that the Louvre is the end of that part of the day. Plan on two to three hours inside and pick two or three wings rather than a tour of everything.

If the Eiffel Tower is the thing you came for, book on the official website, toureiffel.paris, as far ahead as you can. Summit slots for popular times sell out weeks in advance, and a fixed train home leaves no room to come back later.

Lunch, and when to eat it

French kitchens keep shorter hours than British ones. Lunch service in an ordinary restaurant runs from around midday to 14:00, and after that you are looking at a café, a bakery or a brasserie that serves all day. On a day trip this is a timing problem rather than a money problem: if you go into the Louvre at 11:00 and come out at 14:00, you have missed the sitting.

The fix is to eat early or eat late. A bakery lunch in the Tuileries Garden, which is free to walk into, costs a few euros and buys you a seat. A proper meal is better kept for the evening, before the last train, when the same kitchens open again and you have nowhere else to be until check-in. Our estimate for September 2026 is €15 to €25 for a main course in an ordinary central restaurant, less in a café, and more anywhere with a view of something famous; we have not checked individual menus, so treat those as a band rather than a price.

A packaged tour, or booking it yourself

Several companies sell Paris day trips from London that bundle the train with a coach tour, a guide or a river cruise. They suit travellers who would rather not work out the Métro in an unfamiliar city, and they remove the planning this page describes. They do not remove any of the queuing: you go through the same checks as everyone else, and the train times are fixed by the tour rather than by you.

Booking it yourself is cheaper when you book early, and it lets you change your mind in Paris, which matters when it rains or a queue is twice as long as expected. Whichever you choose, compare the package price against two Standard fares and the entry ticket before you decide, and make sure you know what time the group is expected back at the station.

The last train home

The end of the day is where day trips go wrong, and it goes wrong in a predictable way: people plan backwards from the departure time instead of from the check-in time. Eurostar asks Standard passengers to be at Gare du Nord 75 to 90 minutes before the train leaves. Take the later figure, add fifteen minutes for the Métro and ten for the walk, and you get the real answer: stop sightseeing about two hours before your train.

Gare du Nord is a large and confusing station, and the Eurostar entrance is not where you would expect. Follow the signs with a UK flag to Hall 2, then go up to the first-floor balcony that overlooks the main concourse, using the escalators opposite platform 17 or the lifts opposite platforms 9 and 10. Departures for London leave from platforms 3 to 6, and boarding is called about half an hour before the train goes.

Missing the last train of the day means paying for an unplanned night in Paris, because there is nothing behind it. Eurostar charges a rebooking fee rather than voiding the ticket, which is better than nothing, but a seat on tomorrow's first train does not get you to work. Assume nobody is coming to help and keep the margin.

At the London end, an evening train puts you back at St Pancras late. Work out before you leave how you will get to your hotel at that hour, especially if you are staying well away from King's Cross. On Friday and Saturday nights our guide to the Night Tube shows which lines run through the small hours; on other nights you are looking at a night bus or a taxi. If you get in hungry, our round-up of places to eat near King's Cross and St Pancras notes what stays open late.

Frequently asked questions

Can you do a day trip to Paris from London?

Yes. With the first train out and the last train back you get roughly nine or ten usable hours in the city, and with a mid-morning departure closer to six. Pick one major sight and one area to walk, and check that your chosen museum opens on the day you are going.

What time do I have to leave Paris to catch the last train?

Stop sightseeing about two hours before departure. Eurostar wants Standard passengers at Gare du Nord 75 to 90 minutes ahead, and you still need to cross the city and find Hall 2 on the first floor, which is not obvious the first time.

How much does a Paris day trip by Eurostar cost?

The floor is £78 per person for two Standard fares, and most dates cost considerably more. Add €12.30 for an all-day travel pass, €32 for a Louvre ticket if you are not an EEA resident, and whatever you eat, which puts a realistic midweek day at well over £120 a head.

Is it better to stay a night in Paris instead?

Often, yes. Once same-day return fares climb, a cheap hotel plus two less restricted train times can cost little more and gives you an evening, which is when Paris is at its best. Compare both before booking, especially for weekends and school holidays.

How do I pay for the Métro in Paris?

With a ticket bought in advance, not by tapping a bank card at the barrier as you would in London. Île-de-France Mobilités sells a single journey at €2.55 and a Navigo Jour day pass at €12.30 through its app or on a Navigo Easy card, and there are machines at Gare du Nord.
