At the Col du Palet, you enter the restricted zone of the Vanoise National Park. Here, the view over the north face of the Grande Casse is impressive with its hanging glacier. Highest point of the Vanoise massif (3,855 m in altitude), this 900 m dark face is comprised of limestone derived from marine deposits. To its left, the summit of Grande-Motte and to its right, the Aiguille de l´Épena.
