Piedra Rojas is as name suggests red rock area. Although it is named as rock, the area is famous for surreal vista of what Altiplano can offer in the Chilean highland which is on par with what Bolivian Altiplano offers. Piedra Rojas is right next to the Ruta 23 near the border of Argentina. It is a bit of travel from the San Pedro de Atacama. Unlike I heard about the area, access trail paths to the lakeside are off limit and visitors can just enjoy the views of area at the mirador. Although I had seen a lot of similar vistas in the Bolivian Altiplano, Piedra Rojas is just equally as beautiful as others.
