In summer, the Plan du Fou has to be earned: you can reach it on foot either from Siviez or from Tracouet via the Dent de Nendaz and its mountain ridges. The advantage is that this makes it a less crowded summit from where you can enjoy the panoramic view over the Cleuson dam at the bottom of the valley, and the incredible natural surroundings.

In winter, the Plan du Fou comes to life: it is a central point of the 4 Vallées ski domain; its gondola links Siviez to Haute-Nendaz. There is a restaurant whose sunny terrace offers magnificent views over the surrounding mountains. It is also possible to reach it via a signposted ski touring itinerary.
