The Calchaquí Valley stretches across several regions of Argentina, from the southern regions of Catamarca and Tucumán to the northern regions of Jujuy and Salta. We have driven this road several times; most of the photos were taken through the car window, but this is just the tip of the iceberg of what this valley hides. In a few hours, I saw more spectacular ridges and slopes than you could hike in a decade.
We stopped along the way to see the Garganta del Diablo and el Anfiteatro gorges. Both are formed by the river’s current, are enormous, and are dizzyingly interesting.
