Les Rouies, Alpine summit in Écrins massif, France

Les Rouies is an Alpine summit in the Ecrins massif with an elevation of approximately 3,600 meters (11,800 feet). Its plateau above 3,400 meters (11,150 feet) is shaped by glaciers and sits entirely within Ecrins National Park.

The first recorded ascent of Les Rouies was made on 19 June 1873, during the golden age of Alpine mountaineering. The party was led by Frederick Gardiner and Thomas Cox and included William Martin Pendlebury, Charles Taylor, the guides Hans and Peter Baumann, Peter Knubel and Josef Marie Lochmatter. The summit lies on the ridge line dividing the Isère and Hautes-Alpes departments, between the Vénéon valley in Oisans and the Séveraisse valley in Valgaudemar.

The name Rouies is a local Alpine term; the summit's first recorded ascent on 19 June 1873 was made by Frederick Gardiner, Thomas Cox, William Martin Pendlebury, Charles Taylor, Hans and Peter Baumann, Peter Knubel and Josef Marie Lochmatter, a party of British climbers and Swiss guides typical of the golden age of Alpine mountaineering.

The ascent requires a two-day expedition with an overnight stay at Pigeonnier refuge situated around 2,400 meters (7,900 feet). Proper footwear and experience with glacier travel are essential, as the route crosses ice and rocky terrain.
