The first 30 miles (50 km) of the road from Cafayate to Salta in northwestern Argentina has become a tourist destination in its own right, in large part due to the spectacular scenery of Quebrada de Las Conchas (Canyon of the Shells). The site comprises a series of red rock formations eroded into various shapes that have earned each their own nickname.
The most famous of the formations include Garganta del Diablo (Devil’s Throat), El Anfiteatro (the Ampitheater) and Los Castillos (the Castles), but many of the other fancifully named formations are just as photo-worthy.
The best way to see Quebrada de las Conchas is by hired car. The scenic drive along RN 68 can be done in as little as a few hours, including time to hop out for pictures.
