Pierre-sur-Haute is a mountain peak at an elevation of 1.631m (5,351ft) above the sea level, located in the Massif Central, in south-central France. It is in the Sauvain and Job communes, with the boundary between the Rhône-Alpes and Auvergne regions passing through the site. The access is closed to private vehicles.
It is subject to winter snowfalls with such a high summit altitude, and the road can be closed anytime when the access is not cleared of snow. The summit is home to the Pierre-sur-Haute military radio station, a site used for French military communications. A civilian radio relay has also been built at this location by the telecommunications company Télédiffusion de France. The perimeter is surrounded by a high barrier of wood and metal. Military staff and employees arrive via road or tracked vehicles. There are 2 routes to reach the summit. On the western side, the road is paved but pretty narrow. It was asphalted in 1961. On the eastern side, it's a gravel road.
