France rewards the overland traveller generously. Its rail network is one of the densest and fastest in the world, yet step off the TGV corridor and you find slow regional lines winding through vineyards, river valleys and medieval towns that no flight could ever show you. Whether you are crossing from north to south or meandering east to west, here is how to plan a ground-level journey through France.
The backbone: TGV high-speed trains
France's TGV (Train à Grande Vitesse) network ties the country together with remarkable speed. Paris to Lyon takes around two hours, Paris to Marseille about three hours and fifteen minutes, and Paris to Bordeaux roughly two hours. These are journeys that once demanded overnight sleepers but can now be done comfortably between breakfast and lunch.
All TGV services require a reservation in addition to your ticket or rail pass. Book early — advance fares are the cheapest, and they rise as the train fills. The main Paris hubs are Gare de Lyon (south-east), Gare Montparnasse (south-west and Atlantic coast) and Gare de l'Est (east and Rhine).
If you hold an Interrail or Eurail pass, it is valid on TGV trains, but the compulsory reservation carries its own fee. Book these through SNCF or the pass platform — reservation quotas are limited and sell out well before the train.
Regional trains: the slower, richer layer
Beneath the TGV grid lies a web of TER (Transport Express Régional) trains that link smaller towns and secondary cities. These trains are slower, often stop-and-start, and run without compulsory reservations — you simply buy a ticket and board. The trade-off is that the routes themselves are frequently beautiful.
A few routes worth seeking out:
- Lyon to Grenoble — valley floor views of the Alps approaching, roughly 1 hour 20 minutes.
- Bordeaux to Bayonne — flat Landes pine forest giving way to Basque country, under an hour.
- Nice to Breil-sur-Roya — the Train des Merveilles climbs into the Maritime Alps; not a fast option, but one of the most scenic rail journeys in France.
- Nantes to La Rochelle and the Atlantic coast — a coastal corridor rarely considered by visitors fixated on Paris.
The north-to-south overland journey
The classic French overland run goes from Paris south to the Mediterranean. By TGV the direct distance is covered in a few hours, but a slower version — worth taking if you have three or four days — might look like this:
- Paris — spend a day or two before heading south.
- Lyon by TGV (2h) — France's food capital, the Vieux-Lyon cobblestones and the confluence of the Rhône and Saône.
- Avignon by TGV or TER (about 1h from Lyon) — the walled papal city, with easy day trips to the Luberon and Pont du Gard.
- Marseille or Montpellier by regional train — the coast, the Calanques, the end of the line.
This itinerary can be done entirely without flying and requires nothing more adventurous than French rail booking.
Travelling west: Bordeaux and the Atlantic
The south-west TGV line from Paris Montparnasse reaches Bordeaux in about two hours and continues to Bayonne and Biarritz. For a slower, more varied journey, break the trip in Tours or Poitiers — both on the high-speed line — to explore the Loire Valley châteaux by regional train and hire bike.
Bordeaux to Pau, Lourdes and onward into the Pyrenees is served by intercity trains on a secondary line: slower, and more interesting for it.
Cross-border connections from France
France sits at the hub of European overland travel, and its long-distance connections are among the continent's best:
- To Spain: direct TGV from Paris to Barcelona (about 6h40) and from Paris or Marseille to Madrid via the Franco-Spanish high-speed link.
- To Italy: Thello sleeper services have ended but day trains run Paris–Turin–Milan via the Mont Cenis tunnel corridor.
- To the UK: the Eurostar from Paris to London St Pancras runs several times a day in about 2h15, reserved seat required.
- To Germany and beyond: high-speed trains connect Paris Est to Frankfurt (about 3h40) and Stuttgart.

Long-distance coaches in France
FlixBus runs an extensive network across France, connecting major cities as well as smaller towns that trains bypass. Fares are typically well below the equivalent train ticket, and booking is done entirely online. The trade-off is journey time — the coach from Paris to Marseille takes around eight hours versus three by TGV — and comfort over distance.
Coaches are most useful for routes not well served by rail, for very budget-conscious travel, or for travelling to cities close to the Belgian, German or Spanish borders where international coach services cluster. See the FlixBus guide for booking tips and what to expect.
Driving through France
France's motorway (autoroute) network is fast but expensive: tolls add up quickly on a north-to-south drive and can easily reach several dozen euros. The alternative — the free Routes Nationales and Départementales — is slower but takes you through the France that motorways bypass. Car journeys also open up the countryside, the wine regions and the lesser-visited areas not connected by rail.
If you are combining driving with rail, be aware that French motorway services (aires) are well equipped for long stops, and BlaBlaCar is widely used for shared long-distance car journeys, which can cut costs significantly for both driver and passenger.
Frequently asked questions
Do I need to book trains in advance in France?
TGV trains require a reservation and advance fares are substantially cheaper than flexible ones, so booking ahead is strongly recommended. Regional TER trains generally do not require a reservation and can be bought on the day.
Can I travel the length of France in a day by train?
Yes — Paris to the southern coast by TGV takes around three to four hours. Add a stop in Lyon and you can still reach Marseille comfortably in a day, making it one of the more achievable long-distance train days in Europe.
Is France covered by Interrail?
Yes. An Interrail Global Pass or France-specific pass covers SNCF trains. TGV reservations are still required and carry a fee; regional trains are generally included without extra booking.
Are there overnight trains within France?
SNCF has been expanding its Intercités de Nuit network after years of cuts. Services connect Paris with several southern and south-western destinations. Check the current timetable on the SNCF website, as routes and frequencies change.
