Stay observant, as the chamois and ibex, some of which are ear-ringed and with VHF collars, may cross your path. They spend the summer in the towns of Pralognan, Méribel and Courchevel. A part of the population returns to the valley of Maurienne in the town of Modane, where the sunny slopes provide them with better winters. Modane is the site where they are captured for marking.
