Compare cheap car hire and rental quotes for Geneva Airport’s French side (Secteur France): the P21 pickup process, per-supplier links, real prices.
Hire a car on the French side of Geneva Airport (Secteur France) and everything runs on a separate track from the Swiss side: separate signage, a separate customs road, and a separate car park, P21. This guide covers the exact route in and out, which supplier to check first, real prices, and what actually happens if you want to drive the car into Switzerland afterwards.
Quick answer: yes, you can hire from the French side, and for a trip that’s mostly in France it’s usually the simpler choice. Every supplier on this side collects and returns at car park P21, reached via the Route douanière from Ferney-Voltaire. If you land in the Swiss sector and need to walk through to the French one, you’ll need a same-day boarding pass to pass the internal border point.
Getting to the French Sector
If you’re arriving by plane
- Collect your luggage, then go up to the check-in/departures level rather than heading straight for the exit.
- Follow signs for “Destination France”, “Secteur France” or “Porte F”. Generic “Car Rental” signs on this level usually lead to the Swiss side instead, so don’t follow those unless they specifically say France.
- Pass through the internal border point. You’ll need a boarding pass valid for that day to be allowed through, so keep it out rather than packed away.
- Your supplier’s desk sits on the check-in level in the French sector, near the Air France ticket counters.
- After paperwork, a short walk or shuttle takes you to car park P21 to collect the vehicle.
If you’re arriving by car
The French sector isn’t reachable on foot from the public road, so if you’re driving in you need the Route douanière (the customs road) via Ferney-Voltaire. Coming from Switzerland: follow signs for Ferney, go through customs, turn left toward “Secteur français, locations de voitures” onto the Route douanière, and continue through the short tunnel to P21 at the far end. Coming from France: follow signs for Ferney then Geneva, and before customs turn right onto the same road. Either direction ends at the same car park.
Which Supplier: Where to Actually Go
Every French-sector supplier uses the same P21 car park, so the practical differences are desk location within the terminal and fleet, not the collection point itself.

What It Actually Costs
French-side rates typically run 10 to 20% lower than the same category on the Swiss side, quoted in euros rather than francs. That gap narrows once you add anything Swiss-specific, like the motorway vignette (see below). Peak ski weekends (December to February Saturdays) add 30 to 50% to these figures.
| Category | Examples | Daily rate (French side) |
|---|---|---|
| Economy / compact | VW Up, Fiat 500, Renault Clio | £38 to £58 |
| Intermediate | Audi A3, BMW 2 Series, Skoda Octavia | £60 to £88 |
| Full size / estate | VW Passat, Mercedes C-Class, Audi A4 | £78 to £115 |
| SUV | Audi Q7, BMW X3, Volvo XC60 | £85 to £125 |
| 7-seater / people carrier | Ford Galaxy, Seat Alhambra, VW Touran | £95 to £140 |
Two things worth confirming before you book the lowest headline rate:
- Cross-sector one-way fees are real. Picking up French-side and dropping off Swiss-side (or vice versa) isn’t free. As a concrete example, one major supplier charges £12 per day up to a £120 cap for exactly this kind of one-way move between sectors.
- Free cancellation is worth paying slightly more for if your flight times or ski dates could still shift, since prepaid French-side rates are almost always non-refundable.
Returning the Car
- Follow signs for “Secteur France” and then “Car Rental Return” as you approach.
- Enter P21 and follow your supplier’s own return signage to their bay.
- Refuel before you commit to the final access road. There’s no convenient fuel stop once you’re on the customs road itself.
- Photograph the exterior, wheels and fuel gauge at drop-off, not just at pickup.
- Return the keys at the desk if it’s open. Most suppliers also run a key-drop for after-hours returns; confirm the exact process when you collect the car, not when you’re trying to catch a flight.
Driving Into Switzerland From the French Side
Most suppliers allow it, but it needs declaring at pickup rather than assumed. The one thing that definitely doesn’t carry over automatically: the Swiss motorway vignette isn’t included by default on a French-registered rental, since the car itself is registered in France. If your route touches any Swiss motorway, buy the vignette before you reach it, either at the border, a Swiss petrol station, or as an e-vignette through the Federal Office for Customs and Border Security. It costs around £36 and covers you to the end of the following year.
Winter Tyres, Snow Chains and the French Mountain Law
If your route runs through the Haute-Savoie region toward Chamonix or the wider French Alps, France’s mountain equipment law (commonly known as Loi Montagne II) applies between 1 November and 31 March: vehicles must carry winter tyres, or snow chains or socks, in the designated mountain zones. It’s the driver’s responsibility to check whether their route falls inside one of these zones and equip the car accordingly, so this is genuinely worth confirming rather than assuming your rental already covers it.
See our dedicated guides for what’s actually included at this airport: car hire with winter tyres and car hire with snow chains.
FAQ
Which is the French side of Geneva Airport?
It’s Secteur France, reached from arrivals via signs for “Destination France” or “Porte F”, and by road via the Route douanière from Ferney-Voltaire. It operates as a separate desk and car park (P21) from the Swiss sector, even though both sit inside the same airport perimeter.
Where exactly is the Sixt desk on the French side?
From the international arrivals hall, go left and up to the first floor toward Terminal 1; the entrance to the French sector is on your right from there. Like every other French-side supplier, Sixt collects and returns at P21.
Can I drive a French-side rental into Switzerland?
Usually yes, but declare it at pickup and budget for the Swiss motorway vignette separately, since it isn’t included by default on a French-registered car.
Is the French side actually cheaper?
Often, yes, for a trip that stays mostly in France. The saving narrows if you need the Swiss vignette, winter equipment, or a cross-sector one-way drop added on top, so compare the full quoted total rather than the headline daily rate.
Can I take the train instead of hiring a car?
If your trip is Geneva city only, yes: the airport train to Genève-Cornavin takes around 6 to 7 minutes and costs a few francs, which is simpler than parking a rental for a city-only stay. A car earns its cost once you’re heading into the Alps or further into France.
