4.0 by BrandonThis is an automatic translation, the original language is: English.Beautiful climb when you reach the top. However, the way you reach it is quite insane. Just after Les Avants you hit two switch back corners. After the first one you think, "ah, we are going to get a bit of a steep part", luckily this feeling is soon diminished as you lay your eyes on the second switchback. A nice 20+％ gradient awaits you! You may think, naively as I did on my first ascent that this will only last until around the corner. But that is definitely not the case!!!! 70... read more

The ascent from Montreux to Les Avants is wide, well tarmaced and relatively easy to drive, with gradients of no more than 10％. You can see the Dent de Jaman from afar. After Les Avants, where you turn into the Râpes de Jor, it becomes much more difficult with some very steep climbs, definitely over 15％. The route is wonderfully scenic and not very busy, but unfortunately the steep gradients mean that you mainly concentrate on the road. The last kilometre is identical to the ascent from Glion/Caux, which is also quite a challenge at around 13.5％. The route via Glion/Caux is the prettier and, mainly due to its flat centre section, also the easier one
Die Auffahrt von Montreux bis Les Avants ist breit, gut asphaltiert und relativ einfach zu fahren, mit Steigungen nicht über 10％. Man sieht die Dent de Jaman währenddessen schon von Weitem. Hinter Les Avants, wo man in die Râpes de Jor abbiegt, wird es wesentlich schwieriger mit teils sehr stark ansteigenden Rampen, definitiv über 15％. Die Strecke ist landschaftlich wunderbar und wenig befahren, man konzentriert sich aufgrund der starken Steigungen aber leider hauptsächlich auf die Straße. Der letzte Kilometer ist identisch mit der Auffahrt von Glion/Caux aus, dieser hat es auch noch einmal in sich mit ca. 13,5％. Die Strecke über Glion/Caux ist die schönere und, vor allem wegen ihres flachen Mittelteiles, auch die einfachere

700m @ 20+％ (max I registered on my garmin was 26％, on three different occasions). The profile given on this website is NOT CORRECT. The 13％ kilometer is definitely much steeper than that! If you plan to take your spouse, be prepared to sleep on the sofa for the next couple days as I almost had to for not identifying this ridiculous gradient beforehand.
For people who prefer to deviate from this, you have the possibility to take the other ascent to the top from Montreux via Caux. This is much more balanced in gradient. You'd be better off descending this route (if you feel confident in descending steep, narrow roads).
View at the top is excellent, and on a good day you only see a handful of cars on this part, most of the cars go via the Caux road.
If you have a mountain bike, or some rough gravel tires, you can also attempt to ascent/descend on the other side of the mountain. Towards Les Cases, you can either take the golden pass express train back through the mountain or continue your way to Gstaad and then Bulle for a nice 100+km loop.
