This route is accessed by hiking off to the left at the top of the Lanchettes chairlift in Arc 2000. There is a sign stating that you need to have done the Nature Course- this teaches you about the local wildlife on the Aiguille Rouge and is mandatory in order to ski most off piste on the Rouge. You can sometime get away with out it on this route as its very popular, but its at your own risk and I recommend you do the course. The hike is obvious and is only about 5 mins long, once you reach the ridge line you can see clearly your run. You are also stood next to a cross in memory of the many deaths on this part of the mountain, a reminder that you are still venturing off piste!
