Thyon consists of mostly cruisy runs for beginners and intermediate skiers, but Cheminée offers a nice alternative. It’s a fast red which ebbs and flows down the mountain in parallel to the Les Crêtes black. Unlike Les Crêtes, it takes you further down the mountain to virtually the top of Veysonnaz. 

If you reach the top of this run and are trying to head back towards Siviez, take the immediate path to the left which goes under the bridge onto TSA instead.
