The 100th Tour de France next year will start with a first time visit to Corsica.
Riders will race over three stages before re-joining the French mainland at Nice.
The rest of the route will be unveiled on October 24 at the Paris Palais des Congres convention centre, and online at letour.fr.
Last year, almost 150,000 visitors took advantage of the streamed video to discover the details of the route.
Viewers of Eurosport France and Eurosport International will be able to watch the ceremony live.
