The lowlands are fed by streams and springs, the water of which brings minerals to the lowest areas of the quarry basin. Salta, located in the Calchaquíes Valley, is the nearest city to the park entrance. The area was of great importance during pre-Columbian times as a junction and route built by the Incans, which was used by shepherds and their herds.
The highest point in the park is the Cerro Negro at 5,226 metres and there are countless areas to explore such as the Cachipampa plain, the Enchanted Valley, the Obispo Slope, the Incan traced Tin-Tin Straight road one, several churqui forests and Argentina’s largest chandelier cactus woodland. The Piedra del Molino is also another impressive sight – a gigantic granite sculpture at 3,600 metres high with incredible views over the park.
The area is great area for birding with over 100 species, the condor being the most significant, and it holds huge interest to palaeontologists, as dinosaur prints here are said to have an antiquity of 70 million years.
