857 Km
Very difficult
Like Route des Grandes Alpes® in road bike mode, Route des Grandes Alpes Gravel® links Thonon-les-Bains (Haute-Savoie) to Nice (Alpes Maritimes). With almost 28,000 m of positive elevation gain over 857 km of varied road surfaces, it's even more challenging than its illustrious "elder". You may even have to push your bike! By taking the back roads, Route des Grandes Alpes Gravel® will introduce you to other major passes, other villages, other landscapes... An experience of complete freedom that will stay with you for the rest of your life!

Ideally, you should have 10 days, or even better, two weeks, to complete this route in the best possible conditions and fully appreciate the extraordinary landscapes you'll be crossing.

When to go?

Route des Grandes Alpes Gravel® is a "high road", which will take you over high-altitude passes, which no variant, to date, will enable you to avoid. So be sure to ask about road conditions and access to the passes at the start of your trip.

  • By the presence of technical to very technical passages (including single) that can lead to bike "pushes.
  • By evolving inhigh mountain atmospheres.

Easier, thanks to the VAE!

About Gravel

Between road and mountain biking, Gravel is a specific activity, in terms of the routes taken, equipment and gear, preparation, organization...
