FATMAP difficulty grade
This is a long access line where a full day is needed starting from one resort to finish in another resort.
From "Les Combes" ski lift follow the "Mont Grange Sunny Line" which takes about a half day to a full day where skins are great time and energy saver.
The line gets a lot of sun so make sure a good weather window is present and good there's good snow conditions before heading in.
Avalanche risk is really high around here due the high attitude and the face exposure taking a lot of sun.
The main hazard present in this line is the isolated nature of the mountain.
The line finishes at "Plagne to Plaine Dranse line." which leads back to Pré-la-Joux area in Chatel after some more tree skiing.
Only totally expert and autonomous skiers need apply for this line.
