I'm just putting the finishing touches to a non-commercial site :

http://www.corsicabus.org

This site provides bus timetables for the whole island. Since the bus companies are numerous and independent, it has always been difficult for visitors to get a full picture of what is available. Now it is possible.

There is also a link to the SNCF website giving train times, and a page giving other useful links concerning Corsica.[/url]
