Located in northwestern Argentina, the Calchaquí Valley is famous for its wineries, waterfalls and myriad red rock formations. One of the most famous sits just west of Tilcara and is known as the Devil’s Throat (Garganta del Diablo). This red rock gorge has walls 160 feet (49 meters) high with waterfalls trickling down depending on the season.
Devil’s Throat and the nearby Amphitheater formation are the two most iconic red rock formations in the valley, an area on UNESCO’s list of possible World Heritage sites.
The Devil’s Throat formation is located 4 miles (7 kilometers) west of the town of Tilcara in Salta.
