Calchaquí Valleys

Located 90 km southwest of the city of Salta. This ravine is an area of great scenic beauty with very striking rock formations for their reddish colorations. The reserve protects the curious geological formations and high walls of unique landscape value, as well as an important paleontological site belonging to the period Cretaceous. The ravine is geologically relatively recent, produced by tectonic movements that took place in the last two million years.
