This is a delightful run which is relatively non-serious as it is not too steep and usually holds very good snow. It is also worth bearing in mind for flat light days as the cliffs to its R give you good contrast to improve the vis. From the top of the Grands Montets lift follow the Pylones piste until it passes through the rocky ridge with fences onto the front face. Now head straight down and R. You are on a glacier so make sure you are equipped, prepared and have practised crevasse rescue, however unlikely you think falling in a crevasse is- it is possible! A minimum would be each person to have harness, axe, crampons, an ice screw, 3 prussiks, several screwgates, a pulley/DMM Revolver karabiner, a couple of slings and 2 30m ropes in the group. A more modern simple solution substituting for many of the above might be 2 Petzl RAD systems in the group. If you have any doubts about this ski with an IFMGA Mountain Guide.
