The municipality is located in the Sierre district. The main village lies in the Rhone valley with about ten hamlets in the hills above the village. The hamlets include Loye, Daillet, Itravers and Erdesson. Erdesson was formerly known as Merdesson, but the name was changed after it was rebuilt following a devastating fire in 1912.
