From the blue slope "Les Blattins" and the red slope"Pré la Joux" turn left 50 meters before the crossing of the pistes. This line is starts gently until some good steepness skills required. As soon as you see some trees the skiing becomes more technical - the first part is not steep but the line faces west so it can be frozen in the morning. Steepest part need to be very well negotiated as navigation mistake will make you fall into a big ridge if you going to much on the left, trees skiing will be available at the lowest part of the mountain where steepness getting lower before crossing back to "L’itinéraire" blue slope. Steepest part need to be well checked as avalanche risks will be high over there, and crossing back the blue slope "L’itinéraire" can bring some collisions.
