By far the best way to see the island is to rent a car. We found a good deal through Auto Europe, getting a sporty 4-door Renault hatchback from the decidedly unfriendly staff at Hertz at the Ajaccio airport. (Note that Corsica is not known for being the friendliest destination, and while this stereotype was validated by plenty of service industry staff, we found just as many exceptions). It’s virtually impossible to find a car with an automatic transmission, so make sure you can drive a stick shift. The curvy roads wreaked havoc with Sylvia – carsickness was a persistent condition for her as a passenger. If you’re prone to motion sickness, make sure to bring the preventive treatment you need.
For non-drivers, there are buses, taxis, and some train service, but Corsica is not an island meant for mass transit, and it can be especially difficult to get off the beaten path without your own wheels.
