I recently planned a trip from Nice to Madrid and researched the train routes—this journey turned out to be quite interesting. Although there’s no direct train, transfers aren’t too complicated, and you can enjoy plenty of scenery along the way with the Madrid tourist train. Let me share the information I’ve gathered, hoping it helps fellow travelers.
Basic Route Information
There’s no direct train from Nice to Madrid; you’ll need to transfer in Barcelona or other cities. The most common route is taking a TGV or regional train from Nice to Barcelona, then switching to the AVE high-speed train to Madrid. The entire journey takes approximately 10 to 12 hours, depending on transfer waiting times. If you have time when traveling by train from Madrid to France, you can actually spend a night in Barcelona and explore the city.
Fare prices vary significantly—booking in advance can save you quite a bit. Prices I found ranged from €80 to €200, mainly depending on your chosen class and booking time. Renfe’s official website frequently offers early-bird discounts; I recommend checking 2 to 3 months in advance.

Booking Platform Comparison
| Booking Platform | Advantages | Disadvantages |
| Renfe Official Site | Transparent pricing, many discounts | Website occasionally lags |
| Rail Europe | User-friendly interface, multilingual support | Higher service fees |
| Trainline | Integrates multiple rail companies | Complex refund/change policies |
| Station Counter | In-person consultation available | Usually more expensive |
I personally prefer booking directly through Renfe—although the website sometimes loads slowly, the prices are genuinely the best. Note that Spanish railway websites sometimes require a VPN to access payment pages properly.
Travel Experience
The Nice to Barcelona segment offers truly spectacular scenery, with the train running along the Mediterranean coastline. On clear days, you can see the azure waters. I recommend choosing a window seat, especially on the right side. The AVE from Barcelona to Madrid is very fast—about 3 hours—with comfortable carriages and dining car service.
I suggest allowing at least 1.5 hours for transfers. Barcelona Sants station is quite large, and finding your platform takes some time. The station has plenty of restaurants and shops where you can grab food or buy snacks for the journey. I’d heard the station had many pickpockets, but it was fine when I went—just keep an eye on your luggage.
Practical Tips
Bring a power bank and headphones—essential for long journeys. While trains have outlets, not every seat has one. You can buy water and snacks at the station; the onboard dining car is pricier. If you have lots of luggage when [taking the train from Madrid airport], choose carriages with luggage racks—AVE has adequate luggage space.
Also worth noting: European railways don’t strictly limit luggage weight, but size should be reasonable. Large bags need to go in designated luggage areas, while small carry-ons can go in overhead compartments. Overall, train travel is much more relaxed than flying—no need to arrive two hours early, and no worries about liquid restrictions.
