Parque provincial Cumbres Calchaquíes, Provincial park in Tafí del Valle Department, Argentina

Parque provincial Cumbres Calchaquíes covers 82,000 hectares in Tafí del Valle Department, Tucumán, about 130 km from San Miguel de Tucumán. It protects the western cordillera above 3,000 m and the eastern formation above 2,000 m, with summits over 4,500 m and small high-altitude lakes. Vegetation is high-Andean grassland and low shrubs, thinning out on the highest peaks.

The area received protection status in 1965 with provisional boundaries that were finalized seven years later. These two official decrees established it as one of the region's most important nature reserves.

The park holds archaeological sites and remains of the Acalianes or Calianos, the last people to resist Spanish domination at the end of the Calchaquí Wars. Visitors can also see petrified algarrobo trees and Tertiary mammal fossils in one formation.

The park lies about 130 km from San Miguel de Tucumán, in Tafí del Valle Department, around 26°30′S 65°38′W. Its protected area covers the western cordillera above 3,000 m and the eastern formation above 2,000 m, with summits over 4,500 m and high-altitude lakes. Access is by road from the Tafí del Valle area; the high passes and cold, dry high-Andean climate call for warm layers and sturdy footwear.

Between 3,700 and 4,100 m, some areas keep a rare bromeliad called locally "la flora" (Puya weberiana). It grows for decades, flowers only once, releases many seeds and then dies; it has been on Argentina's threatened endemic species list since 2010.
