Siviez
The journey towards either Nendaz or Thyon will take you down Tortin whether you choose to go down the extremely difficult Chassoure run or downloading on the cable car. The ski from Tortin to Siviez is a really nice long blue run, which is great for novices or children, and there is also a luge path if you fancy a change of activity. From Siviez you can then either take the 4-man lift to Combatseline or take the bubble lift to the top of Plan-du-Fou.
Nendaz
The ski into Nendaz is quite challenging, from the top of Plan-du-Fou you have the choice of another demanding itinerary or the bubble down, from there is a nice black run down to a 3-man lift that will take you to the top of Tracouet. Once here the runs are long blues and reds, really pleasant skiing through the trees. I particularly like Nendaz for the scenery and the really nice views of Thyon and the valley.
