Short answer: Ouigo low-cost trains are now on sale for summer 2026, with one-way fares from €19 on the high-speed Ouigo Grande Vitesse network in France and Belgium and from €10 on the slower Ouigo Train Classique. The seats cover travel from 4 July to 12 December 2026 across more than 70 destinations, and Ouigo also runs low-cost high-speed trains in Spain. Book early — the cheapest seats are capped on each train.
If you are planning a summer getaway across France, Belgium or Spain, Ouigo is one of the easiest ways to keep the transport budget low. SNCF's low-cost high-speed brand released its summer 2026 seats on 11 March, opening a long travel window that runs from the July holidays right through to mid-December. The headline is simple: Ouigo low-cost trains from €19 one-way on the high-speed network, with even cheaper fares on the classic-line services.
What the Ouigo summer 2026 sale includes
Ouigo runs two very different products, and the summer 2026 sale covers both:
- Ouigo Grande Vitesse — the double-deck high-speed trains that reach more than 300 km/h, in the recognisable blue-and-pink livery. One-way fares start at €19 for adults and €8 for children.
- Ouigo Train Classique — slower trains on classic lines that link Paris with Nantes, Lyon and Bordeaux at wallet-friendly prices, from €10 and up to about €59 depending on the date.
There are no frills baked into the price — a seat, one small bag and one cabin bag are included — but paid extras (larger luggage, power sockets, seat choice) stay cheap. For a family or a group of friends, the maths usually beats both a budget flight once you add airport transfers and a full-price flexible ticket on the mainline TGV INOUI.
Which routes and destinations are covered
The high-speed network fans out from Paris to more than 70 destinations in France and Belgium, including Lyon, Marseille, Lille, Bordeaux, Rennes, Nantes, Strasbourg, Montpellier, Nice, Toulouse and Brussels. For summer 2026, Ouigo has added new links worth flagging:
- Paris–Bordeaux in about 5 h 30 via Poitiers on the Ouigo Train Classique.
- Strasbourg–Marseille via Lyon Part-Dieu and Avignon.
- A third weekend Paris–Lyon round trip on top of the existing service.
Ouigo also operates as a separate low-cost high-speed carrier in Spain, where its bullet trains connect Madrid with Barcelona, Valencia, Zaragoza, Alicante and more. That Spanish network is part of the three-way price war we break down in our guide to cheap high-speed trains in Spain, alongside Renfe's AVE and Avlo and the rival operator Iryo.
How to book Ouigo low-cost trains for the best price
The cheapest Ouigo seats sell first, so the method matters more than luck:
- Set your dates anywhere between 4 July and 12 December 2026. Mid-week and off-peak departures keep the widest choice of €19 seats.
- Compare the whole corridor. A search on Gopaxo lines up Ouigo next to buses, carpooling and flights on the same route, so you can see instantly whether the train is really the cheapest option that day.
- Book early. Discounted seats are limited per train; prices climb as a departure fills up.
- Check the station. In Paris, some Ouigo trains leave from Marne-la-Vallée–Chessy or Massy TGV rather than the central terminus — factor in the transfer time before you book.
For operator details, timetables and the full route map, see the Ouigo carrier page. Under-30s travelling in Spain should also check whether they qualify for the discounts in our guide to Verano Joven 2026, which can stack savings on cross-border trips.
Is Ouigo actually cheaper than the alternatives?
Usually, yes — but not always. On the busiest corridors, a €19 Ouigo seat booked weeks ahead is hard to beat, especially versus a low-cost flight once you add baggage and the trip to and from the airport. City-centre-to-city-centre rail also saves the two hours you would lose at security and boarding.
The catch is availability: the lowest fares are rationed, so a last-minute Ouigo ticket can cost more than a coach or a carpool seat on the same day. That is exactly why comparing every mode before you commit pays off.
