The pastoral road which passes in front of the Refuge de Plan du Lac serves the various alpine pastures where the farmers graze their herds of cows and sheep. This is where Beaufort, Tome de Savoie and Bleu de Termignon are made. This road is an old communication and trade route between the valleys of Tarentaise and Maurienne, via the Col de la Vanoise that links Pralognan-la-Vanoise to Termignon. It’s the “salt and cheese road”.
