Interandean Valles

The term Interandean valles (Spanish: valles interandinos) refers to those valleys located in the Andes mountains, tipically large flat-bottomed valleys that allow for significant agriculture and settlement.

The interandean valles comprise most of the mid-elevation areas of the "sierra" of Peru, "los valles" of Bolivia and the "Cuyo region" of Argentina.

In Colombia the main interandean valles are formed by Magdalena River and its affluent, the Cauca River.
