Car rentals in Réunion: what to know before you book
Réunion is almost exclusively explored by car. Public transit covers the coast, but it does a poor job serving the interior cirques and highlands, which hold most of the trailheads and viewpoints. Renting a car is essential if you want to explore the island at your own pace.
Roland-Garros Airport in Saint-Denis handles the majority of rental desks. A second airport, Pierrefonds, located in the south near Saint-Pierre, offers a smaller selection but makes sense if you are staying on the southern coast.
How much does a car rental cost in Réunion?
Rates vary significantly depending on the season. Peak tourist season lines up with the southern winter (July to September), which is the coolest and most popular period for hiking in the cirques, along with the year-end school holidays. Prices jump noticeably during these windows, and the most in-demand vehicles (4x4s, economy models) often book out several weeks in advance.
During the low season (March to June, excluding school holidays), rates are more flexible and you will find a broader choice of vehicles on the lot.
Good to know: book your car several weeks ahead for a trip in July-August or during the year-end holidays. The island draws plenty of travelers looking for an escape without a major time zone change, and local demand quickly fills up the smaller fleets.
What type of vehicle should you choose for Réunion?
Réunion's road network is generally in good shape along the coast and main arteries, but mountain roads heading up to the cirques (Cilaos, the access route to Mafate, Salazie) are winding, narrow, and feature tight switchbacks over long distances.
- A city car or compact works fine for a trip focused on the coast and main highways
- A vehicle with a stronger engine makes drives up to Cilaos or the Piton de la Fournaise much easier, as they involve continuous uphill curves
- A 4x4 is not required for most paved roads, but comes in handy for unpaved dirt tracks (access to certain trailheads, Grande Anse beach outside the rainy season)
- Mafate can only be reached on foot or by helicopter, as no cars, not even 4x4s, can drive there
Motion sickness is a real risk on these switchback roads. If you or your passengers are sensitive to it, plan regular stops, especially on the road to Cilaos, which is infamous for its endless turns.
Local agencies versus major brands in Réunion
Major international rental companies have a strong presence at Saint-Denis airport, with desks right on-site or close by. Pierrefonds airport features a more limited lineup dominated by local or regional agencies.
Local Réunion agencies know the island's quirks inside out: the actual condition of mountain roads, seasonal restrictions (certain routes can close temporarily after heavy rains), and insider tips on less-frequented tracks. They sometimes offer more flexible pricing outside the high season, though their fleet can shrink fast during peak travel rushes.
Booking with a major brand
- Desk directly at Saint-Denis airport
- Larger fleet, better availability in peak season
- Standardized procedures, clear security deposits
Booking with a local agency
- Practical advice on mountain road conditions
- Rates that can be more flexible in the off-season
- Smaller selection during peak travel times
Requirements and specific driving rules
Réunion is an overseas department of France, meaning a valid US driver's license is sufficient for short-term stays, and an International Driving Permit is generally not required. Traffic laws and road signs match mainland France.
One island-specific hazard to keep in mind: certain mountain roads (access to Cilaos, the volcano road) can close temporarily after heavy weather or rockfalls. Always check road conditions before heading into the heights, especially during cyclone season from January to March.
Also check with your rental company to see if the contract permits driving on unpaved dirt tracks, as several agencies explicitly exclude them from their insurance coverage.
