Meet the animals that have inhabited these mountains forever: condors, pumas, grey foxes, and more than 200 bird species.
The San Luis Pampean Sierras host remarkable biodiversity. Unlike Patagonia or the Misiones rainforest, the wildlife of the San Luis mountains lives in a delicate balance between aridity and native vegetation.
Birds (200+ species)
The Andean Condor is the undisputed star, but the list includes crowned eagles, peregrine falcons, burrowing parrots, chimangos, and the small long-tailed hummingbird endemic to the region. Dawns are the best time for spotting.
Mammals
The puma is the apex predator of the sierra though it is rarely seen. More common are the grey fox, wildcat, mara hare, and guanaco at higher elevations. In the reservoir there are otters and river otters.
Reptiles
The lampalagua boa can reach 2 meters and is harmless. Liolaemus genus lizards are endemic and display striking colors. In summer rattlesnakes are commonly seen in rocky areas.
Spotting Tips
Rise early, bring binoculars, wear neutral colors and walk quietly. A guide makes all the difference: they know each animal's territory and the best vantage points.
