FATMAP difficulty grade
A long and enjoyable run down to Le Chable which needs good snow cover and is not often in condition - make sure you know you can get down or you are in for a very, very long walk.
From La Chaux, ski directly south on the broad ridge.
Continue down the open slopes towards Sarreyer, making sure never to head too far left.
At 1520m either continue straight down to Sarreyer where you will need to arrange transport or turn right and follow the forest road and you pick up a forest road that continues all the way to Le Chable.
