Sierras Chicas

According to Wikipedia, the range stretches about 250 kilometres from north to south and lies east of the Punilla Valley. Its eastern slopes are less steep than the western ones, and it falls in height toward the south. The Comechingones, the region's Indigenous people, called the range Viarava.

The highest peak is Uritorco, at 1,979 metres above sea level, east of Capilla del Monte, and another notable summit is Cerro Pan de Azucar at 1,260 metres, east of Cosquin. The northern section around Uritorco is the most rugged part of the range, while the rest has gently sinuous slopes.

The Sierras Chicas have Precambrian origins and belong to the Sierras Pampeanas, whose southern extreme is the Sierras de Cordoba. The rocks are metamorphic, and Wikipedia explains that erosion reduced the ranges to nearly flat surfaces over millions of years before the Andean uplift of the Tertiary rejuvenated some blocks and sank others. Because the Sierras Chicas sit on the eastern edge, they stayed modest in height compared with ranges closer to the Andes.

Three rivers that predate the mountains cut across the range: the Anisacate, the Los Molinos and the Primero, also called the Suquia. Rivers flowing from the eastern flank of the Sierras Grandes carve deep gorges through the Sierras Chicas, and dams such as El Cajon, Mal Paso and La Quebrada provide water reserves for cities. Other dams in the wider system, including San Roque and Los Molinos, generate hydroelectric power.

A string of towns lies at the foot of the range. Wikipedia lists La Calera, Saldan, Villa Allende, Mendiolaza, Unquillo, Rio Ceballos, Salsipuedes, El Manzano, Agua de Oro, La Granja, Ascochinga and Jesus Maria among the commuter and satellite towns of Cordoba city. Further along the Punilla Valley, tourist towns include Villa Carlos Paz, Cosquin, La Falda and La Cumbre, with Villa General Belgrano and Santa Rosa de Calamuchita in the Calamuchita Valley.

Tourism centres on these foothill towns, where river valleys, hill viewpoints and a cooler setting than the plains draw visitors. The Wikipedia article is light on climate and visitor detail, so the range is best understood as a green belt of hills and small towns rather than a single destination.

Because the Sierras Chicas are spread over a long north-south strip, a private guided visit with a driver is a practical way to link several towns and viewpoints in a single outing without worrying about navigation. Seasons and trail conditions vary, so plan around local advice.
