Travelling from Trafalgar Square to Place Masséna by train means taking Eurostar from St Pancras International, changing stations in Paris and continuing to Nice-Ville. There is no direct London–Nice train: the daytime journey uses Gare de Lyon, while the overnight variation leaves from Paris-Austerlitz.
The main decision is whether you want an overland journey with a central arrival or a shorter travel day by air. For rail, choose the London and Paris departures together, not just the cheapest Eurostar ticket.

Rail suits an overland journey, while a direct Heathrow flight suits a shorter travel day. Between the same central endpoints, rail travel components add up to about 9 hours, before departure waiting, St Pancras checks and boarding, or extra circulation and connection time in Paris.
Daytime rail rather than a direct Heathrow flight
Pros
- Arrive at Nice-Ville, with a walk into the centre rather than an airport transfer.
- Advance rail offers can help, but compare the onward French ticket and local fares as well as Eurostar.
Cons
- The Paris station change means moving your bags again; with children or bulky luggage, a direct flight may be easier.
- Flight travel components total about 3½ hours before airport formalities, waiting and reaching the Nice bus stop, substantially less than rail.
British Airways and Air France fly directly from Heathrow to Nice. BA’s scheduled flight takes 2 hours 10 minutes. From Trafalgar Square, Piccadilly line access to Heathrow Terminal 5 takes about an hour and costs £6 per adult one way using pay as you go. Terminal arrangements depend on your flight.
At Nice Terminal 1, the bus 12+ component from Parc Phoenix / Promenade to Albert 1er / Phocéens, followed by the walk to the square, takes about 19 minutes. Allow separately for airport formalities and reaching the stop.
A flight might cost roughly £60–£250 per adult one way, depending on advance booking, demand and luggage. The Eurostar headline offer alone does not tell you which complete journey is cheaper: include every ticket and both cities’ access fares.
St Pancras tickets and boarding
From Trafalgar Square, walk to Leicester Square and take the Piccadilly line towards Cockfosters to King’s Cross St Pancras. Follow signs for Eurostar departures at St Pancras International. The access journey takes about 17 minutes, but leave additional room for navigating the station with luggage.
You can reach the South of France using Eurostar, but you change trains in Paris. Eurostar goes directly to Gare du Nord, not Nice. You can buy the Eurostar and onward SNCF journey together, but the Eurostar and TGV INOUI tickets remain separate transport contracts.

On Sunday 4 October 2026, the first London departure is at 08:01 and the last at 20:31. An early departure gives you more onward choices, while a late London departure means planning an overnight stay in Paris rather than a same-day daytime connection.
If disruption makes you miss a Eurostar–TGV INOUI connection, ask staff for proof of the delay. HOTNAT/AJC connection agreements allow travel on the next available train to your destination at no extra cost. Speak to staff on the delayed train or at the connecting station, then present the proof at the station ticket office for an alternative ticket. Compensation is assessed separately for each delayed transport contract, not by the total delay on reaching Nice.
Gare du Nord to Gare de Lyon
- After Eurostar arrives at Gare du Nord, follow signs for the RER suburban trains.
- Take RER D directly to Gare de Lyon, using the platform display to identify a train serving it.
- At Gare de Lyon, leave the RER network and follow signs for the mainline departures.
- Find your onward train by its number on the departure display, then go to its platform ready to board.
The Gare du Nord–Gare de Lyon transfer takes about 13 minutes. The adult Metro-Train-RER Ticket costs €2.55 and allows metro, RER and suburban train travel within 2 hours without exiting the network. Leave extra room for station circulation, waiting and finding your platform, rather than treating the transfer time as the whole connection allowance.
RER D offers a direct transfer with lift access to the platforms. With luggage or reduced mobility, allow extra time to locate the lifts, especially on a first visit to these large stations.

From Gare de Lyon, TGV INOUI and OUIGO Grande Vitesse run directly to Nice-Ville, and the daytime rail leg takes about 6 hours. The earliest departure on 5 October 2026, at 06:03, instead uses OUIGO followed by a TER regional train. Choose both rail departures together, using Paris local time, which is one hour ahead of London.
If your Eurostar arrival leaves no usable daytime connection, stay overnight in Paris. Allow enough time to cross the stations and board the onward train after the RER ride.
The Paris night train
There is no through sleeper from London to Nice. Instead of continuing from Gare de Lyon, you can take Eurostar to Gare du Nord and transfer to Paris-Austerlitz for INTERCITÉS de nuit, the French night train serving Nice-Ville. This replaces the daytime French leg with an overnight journey, not the London–Paris train.
From Gare du Nord, take Metro line 5 towards Place d’Italie directly to Gare d’Austerlitz. The transfer takes about 19 minutes. An adult Metro-Train-RER ticket costs €2.55 for this journey. Allow room for leaving Eurostar and finding the night-train platform.
Select a berth, not a seat, if you want to lie down. Second class offers seats or sleeping berths in shared six-person couchette compartments. First class has shared four-person compartments. Private compartments can also be reserved in either class. Choose the accommodation explicitly when buying the onward ticket, particularly if your group wants its own compartment.
Nice-Ville to Place Masséna
After the daytime train from Gare de Lyon, or the night train from Paris-Austerlitz, you arrive at Nice-Ville, the city’s main long-distance station. Choose Nice-Ville as your arrival station in ticket searches. Nice Saint-Augustin serves regional TER trains, while Nice-Riquier is a secondary station for local TER services, rather than the main hub for this journey.
From Nice-Ville, leave towards Avenue Jean Médecin and continue south to Place Masséna. The final walk is about 1.2 km and takes about 17 minutes. The square brings you into the city centre without another rail connection. Carrying or wheeling your luggage is the deciding consideration: leave yourself room for a slower walk with heavy bags rather than planning an immediate appointment on arrival.
