Paris to Lyon
France's Flagship High-Speed Line

Gare de Lyon is the grand southern gateway of Paris, its belle-époque clock tower presiding over the forecourt and Le Train Bleu - the most extravagant station restaurant in Europe, all gilt and frescoes above the platforms - worth an early arrival on its own. TGVs leave from the main halls; platforms are typically posted about twenty minutes before departure, so watch the boards with a coffee rather than guessing.

Getting there is the easy part: metro lines 1 and 14 and RER A and D all stop beneath the station, putting it fifteen minutes from almost anywhere central. There is no security screening and no check-in - ticket barcodes are scanned at the platform gates, and boarding takes minutes.

The first quarter hour is ordinary railway - out through the south-eastern suburbs on the classic lines, past the confluence country where the Seine collects its tributaries near Melun. Then the train swings onto the LGV Sud-Est and the acceleration is something you feel in your back: within a couple of minutes the TGV is cruising at 300 km/h, and the world outside reorganises itself into foreground blur and slow-moving horizon.

It is worth knowing what you are riding. This line, opened in stages in 1981–83, was Europe's first purpose-built high-speed railway - the experiment that proved city pairs two hours apart by fast train no longer needed an air route. Every LGV in France, and most high-speed lines in Europe, descend from the success of exactly this stretch of track.

Everything Europe knows about high-speed rail was learned first on this line - and it still runs like the proof of concept it was.

The middle hour is deep France: the Yonne valley, then the rolling pastureland of Burgundy - white Charolais cattle, hedgerows, distant church spires - scrolling past at a speed that turns farmland into cinema. The LGV deliberately avoids the towns, which is why the scenery stays so unspoiled and the stops so few.

Le Creusot-Montceau TGV, which a minority of trains serve, is the emblem of that choice: a high-speed station standing almost alone in the fields, built to bring the TGV era to Burgundy's old industrial heartland. Most services flash through without slowing - if yours stops, you are on one of the semi-fast runs, adding a handful of minutes to the journey.

South of Le Creusot the landscape softens into wine country - the Mâconnais on the slopes to the west, the Saône glinting to the east, and, past the occasional stop at Mâcon-Loché TGV, the hills of the Beaujolais crowding the right-hand windows. It is the prettiest quarter of the journey, and the signal that Lyon is close.

The TGV leaves the high-speed line north of the city and threads down the Saône corridor into the urban approach. Watch for the river doubling alongside - Lyon sits at the meeting of Saône and Rhône, and the train arrives between them.

Most trains arrive at Lyon Part-Dieu, the tower-flanked hub of the business district on the Rhône's left bank - not the prettiest quarter of Lyon, but comfortably the best connected. Metro line B runs from directly beneath the station, trams T1 and T4 stop outside, and the Presqu'île - the peninsula heart of the city between the two rivers - is ten minutes away. Vieux Lyon's Renaissance lanes and the Fourvière basilica rise just beyond it.

A minority of services call instead (or additionally) at Lyon Perrache, at the southern end of the Presqu'île - closer to some hotels, less useful for connections. Unless you have a specific reason, Part-Dieu is the stop to choose: it is also where the TER regional network and onward TGVs concentrate, which matters for the next leg of most itineraries.

TGV INOUI is the full-fat product: first and second class, power and Wi-Fi at every seat, a café-bar car, and luggage limited only by what you can carry and label. First class buys a 1+2 layout, wider seats and a quieter working atmosphere - often only modestly dearer when booked early. OUIGO is the low-cost twin: same speed, same route, stripped service, stricter size-limited luggage with paid extras, and rock-bottom fares for those who pack light and book ahead.

The reservation rule has no exceptions: every TGV seat is assigned at booking, and you cannot board with an open ticket. For Interrail and Eurail holders that means a compulsory paid pass-holder reservation on INOUI, drawn from a limited quota per train - book through SNCF Connect or the pass channels as soon as plans firm up, especially for summer and holiday weekends. OUIGO does not accept passes at all; if quotas are exhausted, its cheap ordinary fares are the pragmatic fallback.

Lyon is where the French network opens out. Onward TGVs continue down the Rhône to Avignon and Aix-en-Provence, to Marseille, and along the coast toward Nice; many run through from Paris, so the same platforms serve your connection. Eastward, the TER network climbs into the Alps - Grenoble, Chambéry and Annecy are all direct - making Lyon the natural interchange between the capital and the mountains.

That geography is the quiet argument for breaking your journey here: a night in Lyon buys the bouchons, the Renaissance traboules of the old town and Fourvière's view over the rooftops, and costs your itinerary nothing - the onward trains leave from where you arrived. Paris to the Mediterranean with Lyon in the middle is France's classic rail itinerary for a reason.

Paris built the line, but Lyon is the hinge - everything south and east of here swings off this two-hour ride.
