I am surprised to find this climb on the site, I live almost at the foot and never had the idea to climb up there.
Yesterday I mounted the tubeless wheels equipped with 28mm section tyres and this morning of 21 August 2022 I set off on an adventure because it is an adventure.
I confirm what was predictable, this climb is to be reserved for mountain bikes and Gravels because it is unmanageable with an ordinary road bike.
Of course I did it, but several times I had to put my feet down to pass very degraded sectors, the road is not maintained any more and damaged by the loggers (see photos).
No superb panorama except at the 6th km where one can see the valley and the lake of Grignon, if not one is in the trees permanently, vehicles 4*4 circulate while thinking that there is nobody and one almost mowed me in a lace whereas I was well on my right.
Ps: By VTT or Gravel you can go back down to Essert Blay by joining the road of Fouettaz.
Je suis surpris de trouver cette ascension sur le site, j'habite presque au pied et jamais je n'ai eu l'idée de monter la haut.
Hier j'ai monté les roues Tubeless équipées en pneus section 28mm et ce matin du 21 août 2022 je me suis lancé à l'aventure car s'en est une.
Je confirme ce qui était prévisible, cette montée est à réserver aux VTT et aux Gravel car ingérable avec un vélo de route ordinaire.
Bien sûr je l'ai fait, mais plusieurs fois j'au dût poser pieds à terre pour passer des secteurs très dégradés, la route n'est plus entretenue et abimée par les grumiers ( voir photos ).
Pas de superbe panorama sauf au 6ème km où on peut apercevoir la vallée et le lac de Grignon, sinon on est dans les arbres en permanence, des véhicules 4*4 circulent en pensant qu'il n'y a personne et l'un a failli me faucher dans un lacet alors que j'étais bien sur ma droite.
Ps : En VTT ou Gravel vous pouvez redescendre sur Essert Blay en rejoignant la route de la Fouettaz.
