Overall this route is one of the best routes I have ever done, in particular a section in between Les Scaffarels to Rouaine. Very curvy with the perfect camber and amazing surface. This section ends in Roche Percee.

A superb road with a great surface, lots of open bends with great visibility and very little traffic. This is motorcycling heaven!
An excellent alternative to the Route Napoleon, I think its actually better. Little traffic, some fabulous corners and a mix of hills and valleys. Just over 50 miles with hardly a town in sight, my favourite bit is a stretch through a valley with perfect road surface, long constant radius corners and no junctions, biking heaven. Have a go, then have a rest at the end to let your tyres cool down!!
