Why fly when direct high-speed trains can whisk you from the centre of London to the centre of Paris in less than two and a half hours – that’s quicker than flying when you take airport transfers and waiting around in the terminal into account – plus it’s much better for the environment too. Hop on a train and you’ll be in a patisserie living like a local in no time at all. Before you arrive, why not check out our guide to the best things to do in Paris.

All Eurostar trains have modern, comfortable facilities, plenty of room for luggage, and onboard food and beverage car.

Most of the train companies across Europe release their tickets around three to six months in advance, many of which can be cheaper the earlier you book. If you know the dates you want to travel, you may be able to find some cheaper train tickets from London to Paris by booking early.§
Many of the train services in Europe are also popular commuter services, lots of train companies increase ticket prices during “peak hours” (generally between 06:00 – 10:00 and 15:00 – 19:00 on weekdays). If you can, consider travelling outside of peak hours to find lower priced tickets.
On some of the busier routes, you might also have the option to take a slower or connecting train. It may take a little longer than some high-speed or direct services, but if you have a little extra time on your hands, you might find a cheaper fare. Plus, you'll have more time to enjoy the view of the countryside!

I arrived at London St. Pancras station 45 minutes before my Eurostar train was due to departure, as check-in closes 30 minutes before. The Eurostar terminal is located about a five-minute walk from King’s Cross - St. Pancras tube station and is easy to find as it’s in the centre of the station and well signposted.
There are three border controls to go through at the Eurostar check-in which took around 15 minutes - first I had to scan the bar code on my ticket (which I printed at home), then pass through a metal detector and finally go through passport control (if you’re an EU citizen ID cards are accepted if you don’t have a passport). Note that there are two different document check areas – ID cards on the left and passports on the right. Before leaving home, I checked online if I could bring liquids with me through security but couldn’t find an answer. So, I decided to roll the dice and bought a 1L OJ from the Marks & Spencer next to departures – I can now confirm that you can bring liquids with you. I also discovered that you can bring a maximum of two pieces of large luggage (max dimensions 85 cm x 85 cm) and there are no weight limitations. Unfortunately, you can’t bring any type of animal on Eurostar trains.
Once you’re through security, you’ll find yourself in a wide hall with airport-style seats, three bars, a WHSmith and free toilets. Just like at an airport, there’s a sort of boarding gate that opens about 20 minutes before departure. When the gate is open, intercom will announce the departure platform in English and French (usually platform 9 or 10) and you’ll need to take the escalators to go upstairs. All the seats on Eurostar trains are assigned so you’ll have to find your carriage before boarding. There are up to 22 coaches on a Eurostar train, so it can be quite a walk to reach your carriage.
The train itself
In Standard class the seats are wide and comfortable, I was surprised by how much leg room I had. Every seat has a reclining table and magazine holder – between the seats, there’s a power socket with the UK and European pins. Every carriage has dedicated luggage space and overhead storage, with bathrooms in the middle of every other carriage – all with infant changing facilities. Coaches 6 and 13 (or 9 and 16 on some trains) are restaurant carriages where you can find the “Café Metropole” for sandwiches, snacks and beverages. The Café is quite expensive – €3 for an espresso, around €5.50 for a sandwich and a sandwich + soft drink + snack meal deal for €9.80 (November 2017 prices). Because of the train’s speed and numerous curves, I found it a bit challenging to walk up and down the train – it requires some balancing skills!
I’d suggest checking out the site onboard.eurostar.com – you can see a map of where you are, how fast you’re travelling, how long you have left and (a nice touch) what’s around you. For example, through this website, I discovered that the train passes through where the famous Battle of the Somme took place. This onboard website works even if the WiFi signal is weak (more on this later).
At first sight, entering the Eurotunnel is like entering any other mountain tunnel but you’ll soon notice a drop in temperature in the carriage. In its deepest part, the tunnel is 75 meters deep (the length of 107 baguettes in a line 🥖) and 50 km long! You won’t pass another train in the tunnel as there are actually two separate tunnels, one for each direction.
Arriving in Paris
The Eurostar trains always arrive at the Paris North station (Paris Gare du Nord), located in the north-east part of the city near Montmartre and the Louvre. It’s the busiest railway station in Europe with 214 million passengers a year! When you arrive in Paris you don’t need to show your travel documents again as a check by the French police already took place in London. The station is served by several tube lines and it’s easy to reach all of Paris’ major attractions from here. If you need to take another train to other destinations in France or towards Italy and Switzerland, you’ll have to transfer to another station. Thello trains to Milan and Venice depart from Gare de Lyon, in the south-east of the city – hop on tube line D in the direction of Melun or Melesherbes and you’ll be there in around 30 minutes. If you need to take the tube, you can buy the tickets onboard the Eurostar at the Café Metropole. Remember that, before boarding on a French train, you need to validate your ticket at one of the yellow machines located on the platforms. If you’re at risk of losing a connection train because your Eurostar train was delayed, remember to have your ticket stamped by one of the Eurostar controllers – you can then jump on the next available train to your desired destination without the need to change your original ticket.
