Trekking and ascent of one of the classic mountains of Argentina and Chile
At the foot of the majestic Maipo Volcano lies a lagoon that literally mirrors it, making the two equals in natural beauty.
The Laguna del Diamante Nature Reserve is located 200 km southwest of the city of Mendoza, within the San Carlos department. It was declared a reserve in 1994 and covers an area of 192,000 ha, protecting an important section of the main range crest in the Central Andes, which includes Maipo Volcano at 5323 m and the lagoon of the same name, located at 3300 m. Sighting herds of guanacos throughout the reserve is another of its major attractions.
This volcano has a typical triangular shape that is mirrored in the lagoon, forming the diamond shape its name refers to. It rises, imposing and isolated, part of a group of inactive volcanoes; its summit is located on the west side of the crater, from where it dominates the heights of the region.
This mountain is part of a varied group of 10 peaks and mountains scattered across Argentina, all under 6000 meters, that we have brought together so adventurous mountaineers can find a new challenge to take on. These are well-known mountains, and the idea was to rank them by the difficulty of their normal route, with at least one representative from each region and from each altitude band in the thousands.

2- Cerro Champaquí, Córdoba. 2884 m
