An iconic animal of the alpine grasslands, the marmot is closely related to the squirrel, with 4 digits on the front paws and 5 digits on the back paws. The marmot lives on a family territory that the dominant adults defend tooth and claw. The marmot hibernates and lives idly for 6 months on its reserves of fat accumulated during the summer. The marmot is present throughout the entire route, but especially around the chapel of La Glière.
