How to take a rail journey from London to Nice by day or by night

At St Pancras:

Eurostar is currently suggesting that Standard Class And Standard Premier ticket holders should be at the Eurostar departure area in St Pancras International 90 mins before departure; and that Business Premier ticket holders should be there 45-60mins prior to departure.

The departure gates will close 30 mins prior to departure for Standard Class And Standard Premier ticket holders; and 15 mins prior to departure for Business Premier ticket holders.

Our guide to taking a Eurostar from London is here.

Note that London is in a different time zone to mainland Europe, it is one hour behind; hence what can seem like a discrepancy between the journey time and the interval between the departure and arrival times.

Departing from the Gare De Lyon

The Eurostar will arrive in Paris at the Gare Du Nord, but the train on to Nice will depart from the Gare De Lyon.

This guide explains how to make the transfer between the two stations by RER train.
What's good to know is that the journey from stepping off the Eurostar to being on the concourse at Gare De Lyon will typically take 25-30min - depending on how long you will have to wait for an RER train
The end-to-end bookings on the ticket agents allow over 1hr 20mins between the arrival of the train in Paris and the departure on to Nice.

Or avoid the need to make your own way across the French capital by making a connection between trains at Lille Europe station; see option 2.
Note that Eurostar seemingly doesn't sell that alternative journey option via Lille.

The alternative day trains on from Paris

Some of the journey option sold by the ticket agents involve taking a more basic 'Ouigo' train on from Paris.
The rationale for the Ouigo trains is that they are more basic than the regular TGV InOui trains, because the ticket prices are much cheaper, so if you don't see a much lower price, avoid them if possible.

Book Early And Save: Yes

Online bookings open: up to 6 months ahead of the travel date
This booking period tends to be shorter when looking up journeys between mid August and mid October.

Seat reservations are automatically included when booking tickets for both trains.

Your ticket will not include the RER train across Paris from the Gare Du Nord to the Gare De Lyon.

Eurostar train's general ticket terms:

The only ticket type are the Flexible tickets, but it is the class of service you opt to travel by, which impacts on the terms and conditions of travel.

*Exchanges

Book to travel in Standard and Standard Premier class:
The booked date and time can be exchanged to a different departure to the same destination up to one hour* before departure time.

• If the cost of your new ticket is more than the cost of your original ticket, you will be required to pay the difference;
• If the cost of your new ticket is less than the cost of your original ticket, you will not receive a refund of the difference.

Book to travel in Premier class:
The booked date and time can be exchanged to a different departure up until the end of the previous day, without having to pay any price differences on any other charges.

The Eurostar ticket terms summary is here

Refunds

Book to travel in Standard and Standard Premier class:

• Up to seven days or more before the date of departure you will need to pay a fee of £25 per person for a one-way / single ticket and £50 per person for a two-way / return ticket - So you will only receive any sum you paid in excess of these sums.
• Less than seven days before the date of departure, tickets are non-refundable - Also applies if you exchanged a ticket to an alternative departure, under seven days ahead.

Book to travel in Premier class:
Up until the end of the day before departure date, tickets can be refunded at no additional cost

Seat Reservations on the Eurostar

Reservations are mandatory so seats are assigned when booking - But after a booking has been completed, you use the ‘Manage Your Booking’ facility, which can be easily found on the Eurostar website and select specific seats within the travel class you have chosen.

You don't need to have booked the ticket with Eurostar
You will need to enter a Booking Reference number - but other booking agents such as Trainline, Rail Europe, SNCF Connect, B-Europe and NS International, will also include this number on the communication sent to you. ** .

General ticket terms for TGV InOui trains

The terms on SNCF Connect state:
'Ticket can only be exchanged (adjustment to the current fare) and refunded prior to departure: 40% of the price 6 days prior to departure (€15 max fee). From 30 minutes prior to departure, tickets can be exchanged up to two times (for the same day and the same journey), and are non-refundable after the first exchange.
Which could be clearer, but it seems as though the three key things to be aware of are:

1. Exchanges and refunds are free up to 7 days before departure.
2. If you want to amend your booking in the 6 days before departure:
   If you are travelling on a TGV InOui train you must pay an amendment fee of €19 per person per person for an exchange or a refund.
3. In the 30 minutes before departure, refunds cannot be requested and exchanges are only allowed for the same journey later that day. The same amendment fees apply to the exchange.

Making the connection in Paris:

There is relatively new E.U. legislation which protects travellers against financial loss in the event of missed connections due to train delays, but it only applies to 'through tickets'.
The Eurostar terms and conditions specifically state that when booking journeys which combine Eurostar + Thalys trains 'through tickets' will be issued.
'However, 'for all other journeys that combine a Eurostar Service and a service provided by another carrier (such as the TGV InOui on from Paris) including when purchased in a single commercial transaction, those tickets will be separate contracts and issues regarding delays, missed connections, cancellations, compensation, and the management of aftersales will be handled accordingly'.

But SNCF, which operates the train on to Nice has signed up to Agreement on Journey Continuation (AJC) policy for when a traveller holds separate transport 'contracts' for an end-to-end journey involving more than one train.
So this agreement applies both when 'a bundle' of tickets / contracts is issued as the result of a single transaction - and if travellers have bought several different tickets for their journey, even from different sales channels/ticket providers.
As long as the passenger had planned enough connecting time to change trains (called “reasonable connecting time”), the AJC will apply.

So in usual* circumstances, if a delay to a Eurostar has caused a booked connection on to Nice to be missed, replacement tickets/reservations should be issued at the Gare De Lyon.
*= But that new E.U legislation specifically states that in exceptional circumstances, the train operators do not need to issue replacement tickets - and the terms and conditions on the SNCF Connect website reiterate this.
These exceptional circumstances specifically stated in Regulation (EU) 2021/782 of the European Parliament include:

• extraordinary circumstances not connected with the operation of the railway, such as extreme weather conditions, major natural disasters or major public health crises...
• ...the behaviour of a third party... such as persons on the track, cable theft, on-board emergencies, law enforcement activities, sabotage or terrorism.

Using Rail Passes on Eurostar:

Rail pass users can now pay reservation fees to travel on Eurostar trains, in a similar manner to other international European high speed trains.

The new rail pass reservation fees are similar to the cheapest single journey ticket prices, but as those cheapest tickets can sell out quickly, it's likely that the rail pass reservation fees will save money.

You can purchase these online with no booking fees on B-Europe
Booking in advance is recommended as it's not unknown for rail pass reservations on specific Eurostar services to sell weeks in advance, there is evidently limited availability per departure.

If you are a UK resident, your rail pass + reservation is only valid if you take a train from the UK on the first day that your pass is valid for and return to the UK on the final day that you will be using a pass.

If you want to make a London to Nice train journey and avoid travelling via Paris then an option is to make comparatively straightforward connections between trains in both Lille and Avignon.
Though the Eurostar website doesn't seemingly off this end-to-end journey option.

The positive of taking this combination of trains is the avoidance of having to make the transfer across Paris from the Gare du Nord to the Gare de Lyon.
In particular Avignon TGV is an exceptionally easy station in which to change trains.

The transfer times between trains will be around 35 mins in Lille and around 1hr in Avignon, which will typically allow the connections to be relatively uncomplicated - if the trains are on schedule you won't be rushing through an unfamiliar station against the clock, and neither will you be hanging around awaiting departure.

Though the potential negative is that those transfer times won't allow much contingency in the unlikely event of delayed trains.
Completing the end-to-end journey in a single day is dependent on making that 35 min connection in Lille.

Note that London is in a different time zone to mainland Europe, it is one hour behind; hence what can seem like a discrepancy between the journey time and the interval between the departure and arrival times.

Departing from Paris

The overnight train departs nightly* from a different station in Paris to that which the TGV trains depart from,
*= the train seemingly isn't available on some Saturdays.

The Eurostar will arrive in Paris at the Gare Du Nord, but the Intercités De Nuit train on to Nice will depart from the Gare Austerlitz.
Metro Line 5 (direction Place d'Italie) provides a direct link from Gare Du Nord to Austerlitz, but think twice if you have luggage.
The Austerlitz Metro station on line 5 is above ground and there are no escalators/lifts down to ground level, where the mainline trains depart from, you have no choice but to use the stairs.

Or if time is in your side* take the bus, Line 91 goes to Austerlitz from this stop on Rue de Saint-Quentin.

*= The ticket agents typically sell end-to-end journeys which involve departing from London at around 16:30, with an arrival into Paris around 1hr 5mins before the usual departure time of the train on to Nice.
The station-to-station transfer by Metro will take around 30mins, from stepping off the Eurostar at the Gare Du Nord to being on the concourse at the Gare Austerlitz.
So departing London at around 16:30 will only around 30mins of contingency in the event of a delay to the Eurostar - but it is essential to make the connection in time, there isn't an alternative option, which would avoid the need to stay overnight in Paris.
Hence it can be good idea to book separate tickets, so that you can depart London earlier in the day.

When the end-to-end journey is available to book online, the ticket agents will typically opt for the train which departs London at around 16:30
However, this Eurostar will typically arrive in Paris only 1hr 5min prior to the departure of the train on to Nice.
It is essential to make the transfer in time, but this option allows for around 40mins of delay to the Eurostar.
So to provide more contingency time, this is an instance when booking separate tickets can pay off, so that you can leave London earlier.

Book Early And Save: Yes

Online bookings open: up to 6 months ahead of the travel date
