Find out everything you need to know about travelling with your children.

Children under 4 years old

Kids under 4 can travel for free on Eurostar, provided they can sit on an adult's lap. Here's how it works:

  • Your child will need to sit on your lap throughout the whole journey.
  • If you want them to have their own seat you'll need to buy a child ticket (see below).
  • Travelling with more than one child under 4? They'll each need to sit on an adult's lap.
  • Travelling alone with two or more kids under 4? You'll need to take one on your lap and buy child tickets for the others.
  • Remember, kids of any age need their own passport to travel.

Fares for children aged 4 to 11

Special fares for kids aged 4 to 11 years old are available in Standard class.

A child ticket can only be booked with an adult ticket on If you need to book a standalone child ticket, please get in touch with our contact centre.

Child facilities on board

Baby changing

All of our trains have baby changing facilities. If you'd like to sit nearby, simply log in and choose your seats once you've booked.

Family seating

If there's space, you can also choose to sit around a table so you can spread out the colouring books or get stuck into a game on the way.

Children's meals

Child-friendly options are available at Café Métropole, our onboard bar buffet. We don't sell baby food but we're happy to help by warming it up at Café Métropole.

If you're travelling in Standard Premier with your child(ren), you can request a child meal for them. Visit Manage your booking at least 24 hours before travel if you'd like to request a child meal.


Child luggage allowance

Kids travelling on a child ticket can take:

  • 1 piece of luggage (up to 85cm long)
  • 1 piece of hand luggage

Pregnant or travelling solo with children under 4

If you think you need an extra pair of hands, you can pre-book assistance for your journey.

One of our team will be able to support you through the whole departure process, from going through the ticket gates to passing security and stepping on board.

We’ll also be able to help you once your train arrives in its destination. If you only need assistance for part of the departure process, make sure you let our teams know so they can help you accordingly.

Some of our local providers in France and Belgium can only offer assistance to pregnant women, but aren’t able to do so for adults travelling alone with children.

Please let us know at least 48 hours in advance what kind of help you’ll need. Find out how to pre-book assistance

Unaccompanied under 18s

Unaccompanied minors (up to the age of 18) will require additional documentation for travel. Please read the relevant section below and we also strongly recommend checking the latest government advice before you travel – from both the country you’re departing from, and the country you are travelling to.

  • Children under 12 years old:

Children under 12 must travel with a responsible person aged 16 or older.

  • Children 12 to 15 years old (inclusive):

Children 12 to 15 (inclusive) can travel on their own to some Eurostar destinations, as long as they’ve got a fully completed Eurostar unaccompanied minor form and only travel on trains departing between 06.00 and 17.00 local time. The form must be signed by their parent or legal guardian (or by a responsible adult given consent by the parent or legal guardian) at the station in the presence of a member of the Eurostar team. The child will need to keep this signed form with them throughout their journey and show it to the onboard team if they’re asked. 

When the parent or legal guardian gives written consent for the young person to travel, they accept and agree that the young person will travel unaccompanied and be treated as an adult passenger (i.e., the young person will not be supervised by a member of the Eurostar staff) for the entirety of the trip. The responsible person must also ensure arrangements are in place for the young person to be met on arrival. 

Please note: Children under 16 years of age cannot travel unaccompanied on our direct trains to or from the Netherlands.

16 to 17-year-olds can travel by themselves, as long as they’ve got all the usual travel documents and meet all the legal requirements.

  • Documents your child will need:
    • Eurostar ticket
    • Passport
  • Additional requirements for French residents
