The petrified forest causes a special impact when you see it for the very first time: the biggest in the world is that of Sarmiento.

Their gigantic petrified logs formed 65 millions year ago were part of the ancient forest that used to cover the current steppe, unloaded by rivers and streams coming from the hills located to the west. Scattered in the area, as you follow the walking trails, you can see palms trees and conifers turned into stone, also autochthonous fauna, such as guanacos, gray foxes, piches, black eagles and harriers.
