FATMAP difficulty grade
This is an easily accessed line.
Turn right from the top of the "Chaux-des-Rosées" chairlift; the entrance is gentle and quite long until you get in the middle section.
The middle section is really steep with a big cliff in the middle of the line.
There are also rocks which can be sticking out due the westerly aspect (and resulting sun) of this line.
This can also make the line icy in the morning.
The line also has avalanche danger, some tricky skiing and tricky navigation.
The line finishes on the red piste "Les Rennes" which leads back to the same chairlift or Pré la Joux.
