You can also catch a not inexpensive bus right at the airport that runs quite regularly (there's a ticket office and you can buy either one-way or "aller et retour") and is one heck of an exciting ride, depending on the driver. Not a bad alternative to driving the corniches if you're at the end of a long trans-atlantic. The train is considerably cheaper, although you would have to go by taxi or bus to "la gare."
