Published on 09/07/2026 at 08:10 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Quebrada de Humahuaca in northern Argentina is an Andean valley where striped mountains, a winding river and centuries of human movement share a single narrow corridor. Set in Jujuy Province and named for the town of Humahuaca, it forms a long north–south passage between the high plateau of the Puna and the lower eastern ranges.
An Andean corridor carved by the Río Grande
Quebrada de Humahuaca is a narrow mountainous valley in Jujuy Province in the north-western part of Argentina, extending for about 155 km (96 mi) in a north–south directionnarrow mountainous valley. The valley is carved by the Río Grande, also known as the Grande de Jujuy, which runs along its floor from the cold high Andean plateau towards warmer lowlandsRío Grande corridor. Steep slopes rise on both sides, creating a clear sense of travelling through a corridor rather than across open country.
To the west the valley is flanked by the high plateau of the Puna, and to the east it meets more wooded ranges that lead towards temperate valleysPuna and Sierras Subandinas. Travelling along Quebrada de Humahuaca means moving between different bands of altitude and climate, from high, cold plateau landscapes to drier mid-valley sections and then towards lower, more vegetated ground further south.
Layered rocks and villages in a cultural landscape
The slopes of Quebrada de Humahuaca expose layers of sedimentary rock in different colours, forming ridges and cliffs that give each stretch a distinct profilecolourful sedimentary strata. In places those layers create striped hillsides with contrasting bands of red, brown and lighter tones. Erosion by the Río Grande and its tributaries has cut into these rocks, producing side ravines and slopes that reveal more of the valley’s geological structure.
Along the valley floor and lower slopes sit villages and small towns, including Tilcara, Tumbaya and Humahuacatowns of Tilcara, Tumbaya and Humahuaca. Fields, terraces and paths surround these settlements, linking them to the river and to each other. Quebrada de Humahuaca is described as a cultural landscape, where cultivated land, settlements and archaeological sites are part of the same valley settingcultural landscape inscription. From village streets and viewpoints, the combination of built structures and coloured slopes is a defining sight.
An ancient route recognised as World Heritage
Quebrada de Humahuaca follows the line of a long-established route used by caravans and travellers moving between high Andean lands and the plains further southmajor cultural route. Over thousands of years this corridor carried goods and people, linking different cultural regions along the Río Grande. Sections of the valley are associated with pre-Hispanic and pre-Inca settlements whose field systems and structures are still visible in the landscapepre-Hispanic settlements.
In 2003 Quebrada de Humahuaca was inscribed on the UNESCO World Heritage List as a cultural site, reflecting both its long history of use as a route and the combination of settlements and valley landforms2003 World Heritage inscription. The designation covers a substantial area of valley and surrounding slopes, including the departments of Tumbaya, Tilcara and Humahuaca in Jujuy Provinceextent of the protected area. Visitors encounter not only dramatic landforms but also traces of historic routes, agricultural plots and village layouts that reflect long-standing patterns of life in the Andean north-west.
