You already know it: to visit La Réunion, you need a car. The best, is even to rent a SUV. It is way more comfortable to drive this kind of car in the mountainous road as it gives you more power and more visibility.
you can rent an economy car if you prefer of course, but this kind of cars is better when you stay in the cities for a business trip for instance.
To rent a SUV, you need to be 23 years old minimum and be licenced for more than 2 years.
We have Automatic SUV to rent, so if you have an automatic driving licence, you can still rent a SUV in La Réunion.
