Vertical drop: 150 m
Technical difficulty: Fairly serious.
From the classic Chancel side, take a sharp right turn towards Breche de Pacave and continue down a wide slope to the lake. From here you can reach all the couloirs.
Be careful of wind-slabs may form on the traverse just before the couloirs, high risk of slipping on hard-packed snow. Patou is located skiers right, Le Banane is located in the center, Couloir du Lac is on skiers left.
