Nevado Juncal, Mountain summit in Los Andes Department, Chile.

Nevado Juncal is a mountain summit in the Central Andes located at the border between Chile and Argentina. The peak rises to approximately 5,950 meters and sits in a region shaped by glaciers that feed the water systems of nearby valleys.

The first ascent via the hanging glacier, and the fifth overall, was made in 1951 by Wolfgang Förster, Eberhard Meier, Ludwig Krahl and Wilhelm Niehaus of the German Andean Club of Santiago. Robert Helbling carried out the first measurements of the massif between 1908 and 1918, and Luis Lliboutry confirmed them in 1956.

The summit lies on the Chile–Argentina border, with the peak itself in Chilean territory, at the boundary between the Valparaíso and Santiago Metropolitan regions. Its name is shared with the glaciers on its flanks, including Juncal Norte and Juncal Sur, which feed the Juncal and Olivares rivers.

The summit sits in a remote, high-altitude alpine setting that requires specialized mountaineering gear and experience. Visitors should prepare for extreme elevation and variable weather conditions in this mountain region.

Two major glaciers named Juncal Norte and Juncal Sur cover the mountain's flanks and shape the water systems of the entire Aconcagua region. These ice masses are key to the hydrological patterns and long-term water supply for the valleys below.
