The first 10 kilometres of this climb (up to hamlet Le Faz) is known as Montée du Faz; I climbed 'm up to this hamlet in August 2023. It is a tricky climb as there are long stretches of 8-10％ rise and the climb is open (little shade): if there is no wind it is hot here. Up to hamlet Le Faz, signs along the road indicate the gradient for the next kilometre.
De eerste 10 kilometer van deze klim (tot in gehucht Le Faz) staat bekend als Montée du Faz, ik heb 'm tot dit gehucht in augustus 2023 beklommen. Het is een lastige klim, want er zijn lange stukken van 8 tot 10％ stijging en de klim is open (weinig schaduw): indien er geen wind is het hier warm. Tot gehucht Le Faz staan langs de weg bordjes die het stijgingspercentage voor de komende kilometer aangeven.
Of the many accesses to the Mont Noir pass, this is probably the least attractive from a touristic point of view but also the most difficult. In particular, there is a very steep section after the intersection with the road to Presles... I have seen cyclists dismounting there several times! Be careful, the last part, in the huge forest of Coulmes, can be in bad condition. This is the case for all the access roads as soon as you approach the pass. So be careful on the way down, whatever route you choose.
Des nombreux accès au col du Mont Noir, c'est probablement le moins attrayant touristiquement parlant mais aussi le plus difficile. Il y a notamment un passage très pentu après l'intersection avec la route menant à Presles… j'y ai vu plusieurs fois des cyclistes mettre pied à terre ! Attention, la dernière partie, dans l'immense forêt des Coulmes, peut être en mauvais état. C'est d'ailleurs le cas de tous les accès, dès qu'on approche du col. Prudence donc à la descente, quel que soit l'itinéraire choisi.
