Réserve de biosphère Laguna Blanca, Natural biosphere reserve in Catamarca Province, Argentina.
Laguna Blanca is a biosphere reserve on the high plateau of Catamarca Province, in northwestern Argentina. At its center lies a salt lake surrounded by Andean peaks that tower well above the treeline.
The reserve was established in 1979 with the main goal of protecting vicuna populations that had been shrinking for years. In 1982, it was accepted into UNESCO's Man and Biosphere program, which brought broader attention to the area.
The six small villages inside the reserve keep a way of life built around raising goats and sheep, a tradition that shapes daily routines at high altitude. Visitors who pass through these communities can notice the simple stone houses, the animals grazing nearby, and the slow pace of a pastoral life far from any city.
Getting to the reserve is easiest by car, with the nearest towns of Antofagasta de la Sierra or Belen serving as starting points for the journey. Accommodation in the area is basic, and electricity often comes from generators, so it is worth coming prepared for limited services.
Near the central lake, Salamanca Cave holds prehistoric rock paintings that show people have lived in this part of the Andes for thousands of years. The cave is easy to overlook, yet it offers one of the most direct connections to the ancient history of the region.
