The commune counts fifteen villages and hamlets. Basse-Nendaz is the administrative and parish capital.

Near Sion, the commune of Nendaz is located in the middle of the Rhône valley, on the left bank. Its immense territory of 8593 hectares has several unique characteristics: it follows the contours of the valley of the same name and extends from the fertile plain to the eternal snows.

The forest occupies nearly a quarter of its land. It plays a notorious protective role, protecting against erosion and avalanches. The valley is divided into two slopes by the Printse, a tumultuous river, both source and outlet of a multitude of bisses (artificial water channel) used for irrigation.

Nendaz is crowned with magnificent peaks, such as the Rosablanche which, culminating at 3336 meters, is the most beautiful alpine belvedere of the central Valais or the Mont-Fort (3330 meters) today accessible to all thanks to the ski lifts.
