Qhapaq Ñan, Andean Road System (Argentina, Bolivia, Chile, Colombia, Ecuador, Peru)

Qhapaq Ñan is an extensive Inca communication, trade and defense network of roads, covering more than 18,000 miles through one of the world’s most extreme geographical terrains. The road links the snow-capped peaks of the Andes to the coast, running through hot rain forests, fertile valleys and absolute deserts.

Quebrada de Humahuaca (Argentina)

Quebrada de Humahuaca, a natural valley corridor in northwestern Argentina, has been used over the past 10,000 years as a crucial passage for the transport of people and ideas from the high Andean lands to the plains. Its distinctive pre-Hispanic and pre-Incan settlements, along with their associated field systems, form a dramatic addition to the outstanding landscape.
