Reserva Provincial Castillos de Pincheira, Protected natural area in Malargüe Department, Argentina
Reserva Provincial Castillos de Pincheira is a protected natural area covering more than 600 hectares with rock towers that resemble castle structures. These formations were shaped by ancient glaciers and water erosion over thousands of years.
In the early 1800s, the Pincheira brothers, outlaws from Chile, used these rock formations as a refuge for their operations. The area is named after them due to their notable presence here.
The Huarpe people lived in this territory long before other groups arrived in the region. Today, traces of their presence remain visible in the landscape and archaeological finds.
The area is accessible from Malargüe city via Fortín Malalhue Street with regular bus service available. Guided tours through the local tourism office will help you understand the geological features you see.
The sedimentary rocks here display distinct color bands and layers from different time periods that are clearly visible to visitors. Archaeologists discovered arrowheads and pottery from ancient times, showing that people knew these formations long before modern settlement.
