#11: Col de la Cayolle (Alpes-Maritimes)
The one between two legends
There are climbs that are simply outshadowed by bigger, harder difficulties around them, or simply because the legend didn't establish itself on their slopes. At its west, the quite known col d'Allos, taken in every Tour de France between 1911 and 1949, then to be only included five times since, the latest one being the 2000 edition. At its east, the cime de la Bonette. Simply the highest road in France, but surprisingly, only took 4 times by the Tour since 1962, and being passes by the last time by the peloton five years ago. That simply proves how much the Tour doesn't love going into the roads going from Barcelonnette to Nice, and doing the Savoie passes again and again so they can climb them twice in a Tour.
Let's talk about the pass that is located between Allos and Bonette: the col de la Cayolle. It's kind of a twin to Allos, but except that its harder side is the southern one, and it goes a little bit higher, topping at 2326 meters. It links the Var valley to the Ubaye valley. The latter being the point in common between the three climbs: they all start or end up in Ubaye. The Tour de France visited Cayolle only three times, in 1950, 1955 and 1973. Only the first time climbed the hardest side, as the stage went from Nice to Gap, so in other words, from south to north.
Being opened mere days before the start of the first World War, the col de la Cayolle is one of the few climbs that go above the 2000 meters bar. If its north side, starting from Barcelonnette, is the easiest, with many nearly-flat kilometers in the ascent, the final part being the steepest. The south side however, starting from Saint-Martin-d'Entraunes, is a real challenge that goes for over 20 kilometers.

Starting from Saint-Martin-d'Entraunes, the climb is rather easy, averaging 4 % on nearly 6 kilometers. But the real deal begins from Entraunes, with goes straight up with an 8 % portion before an easier part until the heights of Estenc. Then the beauty of the altitude and the wilderness offers itself to the rider during 7 kilometers, at 7.5 % average, with some ramps over 10 %, in a stunning scenery which can only be found in such altitudes. Of course, it might not be as spectacular as the backdrop seen from the Cime de la Bonette, but it's still a delight for the eyes while the whole body and the legs burn from the effort of this demanding climb, and the lungs trying to take as much oxygen as they can above 2000 meters.
If ASO had the choice to go into the deep south east of France, they'd probably choose Bonette for the height, or Allos for the legend. But if a stage had to come from the Nice region and going up to the spectacular Serre-Ponçon lake (which will host an individual time trial this year) then Cayolle would be a definitive alternative. It's a climb that is worth riding, both for amateurs and professionals. It might not be as legendary as the Bonette or Allos, but it keeps a part of secrets and has some kind of charm. That's the advantage of being unknown: you never know what you'll face in the next kilometers.
