Piz Ault is a mountain of the Glarus Alps, located south of the Oberalpstock in Switzerland.

Three ridges lead to the peak with a fourth one not very distinct to the south.

The municipalities are Disentis and Sedrun on the south and Silenen to the northeast.

In winter time the area is accessible by a T-Bar ski lift which reaches up to some 200 meters (660 ft) under its peak in its southwestern face.

The ski resort[2] is accessible from Disentis, lying south of Piz Ault in the State (Canton) of Graubünden.
