Find the Cheapest Hertz Car Hire Geneva Airport French deal: how to reach the French sector, P21 car park pickup, and correct return routes.
This guide is for travellers using Hertz car hire in the French sector of Geneva Airport. The French side works very differently from the Swiss side, with separate terminal access, road routes and car parks.

Below you’ll find exactly how to reach Hertz, where the cars are collected (usually P21), and how to return without accidentally ending up on the wrong side of the airport.

Understanding the Hertz French-side setup
Hertz operates separate rental locations on each side of Geneva Airport. The French-side Hertz is part of the airport’s Secteur France, which functions almost like a mini airport within the terminal.
- Terminal access: via “Secteur France / Porte F” inside the terminal
- Road access: via Ferney-Voltaire (France), not Swiss airport roads
- Vehicle collection: French-sector rental car park, commonly P21
- Best suited to: trips entirely or mostly in France
How to reach the Hertz desk (French sector)
If you arrive by plane
- Land at Geneva Airport and collect your luggage.
- Go up to the Departures / Check-in level.
- Follow signs for “Destination France”, “Secteur France” or “Porte F”.
- Pass through the internal border into the French sector.
- The Hertz French-side desk is located on the check-in level alongside other France-sector rental companies.
Tip: ignore general “Car Rental” signs unless they explicitly mention the French sector. Many lead to the Swiss side.
If you arrive by car (from France)
- Drive toward Geneva Airport via Ferney-Voltaire.
- Follow signs for “Aéroport – Secteur France”.
- Use the customs access road into the French sector.
- Proceed as directed for Hertz / P21.
Picking up your Hertz car (P21 French sector)
On the French side, Hertz vehicles are normally collected from P21, the dedicated French-sector rental car park.
- Complete your rental paperwork at the Hertz desk.
- Follow the signed route or staff instructions to P21.
- Walk to the Hertz bays within the car park.
- Locate your vehicle using the bay or row number.
- Before driving away, take photos of all sides, wheels, windscreen, fuel level and mileage.
Returning a Hertz car on the French side
The single most important rule
For returns, always navigate to “Geneva Airport – Secteur France – P21”. If you follow standard airport signage without specifying the French sector, you may be routed to the Swiss side and forced to loop back.
Return steps
- Approach the airport via Ferney-Voltaire.
- Follow signs for Secteur France, then Car rental return.
- Enter P21 and follow Hertz return signage.
- Park in the Hertz return area.
- Take final photos of the car and fuel gauge.
- Return keys at the desk if open, or use the key drop if returning out of hours.
Fuel, tolls and borders (French-side specifics)
- Fuel: refuel before entering the final French-sector access roads.
- Swiss motorway vignette: not included by default on French-side rentals.
- Driving into Switzerland: usually permitted, but must be declared at pickup.
- Tolls: French motorways use toll booths; carry a card.
When the Hertz French side makes sense
- Staying in France only
- Trips to Chamonix, Morzine, Les Gets or Annecy
- Travellers who do not need Swiss motorways
- Anyone wanting to avoid Swiss vignette costs
