Cerro Bonete, Mountain summit in La Rioja Province, Argentina.

Cerro Bonete is a mountain peak in northern La Rioja that rises to about 6,759 meters above sea level with steep slopes and a pyramid-shaped top. The surface is covered with volcanic rocks and displays the jagged formations typical of this region.

Measurements from radar satellites in the early 2000s corrected earlier estimates and established the peak's height at approximately 6,759 meters. This scientific survey resolved long-standing questions about the mountain's true elevation.

The name Bonete comes from the bonnet-like shape of the summit cones of both this mountain and the nearby Bonete Grande, 12 km to the north. The two are often confused: Bonete Chico is the higher one, at 6,760 m, while Bonete Grande reaches 5,945 m.

Visitors should prepare for high altitude and harsh conditions, as the peak sits in a remote location where winds are strong and temperatures swing dramatically. The best time for expeditions is during the local dry season when weather is more stable.

Walther Penck climbed the mountain from the east in 1913 and, in cloud and fog, believed he had reached the summit; his altimeter read 6410 m, and it is presumed he only gained a pre-summit. The first confirmed ascent came in 1971 with Cicchitti, Urriche and Brignone.
