As you leave from Attelas, turn left in the direction of Lac des Vaux, then turn in front of the valley chair lift station and follow the sign "Vallon d'Arbi, Col des Mines". Make sure that the passage is open and not closed for safety reasons. Ski down into the first little valley, which ends with a small blue ice cascade under which a brook still runs. Continue skiing between the high snow walls. Choose one of the three options available, depending on your skill and the condition of each route. The magnificent peaceful surroundings, the gentle murmur of the flowing water and the white slopes dotted with a few larch trees invite you to stop and rest for a while (a more than adequate reward for the challenging descent). A trail leads you to the La Tzoumaz cable car. Important: Please ask the piste service about the condition of each route. It is advisable to carry out this half-day tour in the company of a guide.
