Quebrada de Humahuaca

The Quebrada de Humahuaca is a narrow mountain valley located in the province of Jujuy in northwest Argentina, 1,649 km north of Buenos Aires. It is about 155 km long, oriented north–south, bordered by the Altiplano in the west and north, by the Sub-Andean hills in the east, and by the warm valleys in the south.

The name quebrada translates as a deep valley or ravine. It receives its name from Humahuaca, a small city of 11,000 inhabitants. The Grande River, which is dry in winter, flows copiously through the Quebrada in the summer.
