Sirac, Mountain summit in Hautes-Alpes, France

Le Sirac is a 3,441-metre summit in the Écrins massif, the southernmost of the range's major peaks. It forms the western promontory of a long ridge separating the Valgaudemar from the Haut-Champsaur, linked to the southern Bans chain that ends abruptly above Lake Vallonpierre. Its upper part is a jagged crest of dark grey rock with at least four points, snow lying in the gullies below.

The first ascent was made on 2 July 1877 by William Auguste Coolidge with Christian Almer and his son, via the former Gouiran glacier, the south shoulder and the east side of the south ridge. On 3 September 1908 the first ascent by a woman was made by Mme G. Buisson with M. G. Buisson and Eugène Estienne.

The mountain serves as a well-known landmark for climbers exploring the southern Alps and is regularly visited by hikers seeking alpine routes. Its location and reputation make it a reference point for those navigating this mountain region.

The most direct approach to the summit follows the western slope, with marked trails leading toward the Chabournéou and Vallonpierre shelters as orientation points. Visitors should be experienced mountain walkers and plan their visit according to weather conditions in this high-altitude environment.
