Argentina–Bolivia border, International border between Argentina and Bolivia in South America
The Argentina-Bolivia border runs across approximately 742 kilometers through diverse landscapes including mountains, valleys, forests, and flat terrain in the Chaco region. This boundary line separates the two countries and contains several established crossing points where travelers regularly move between them.
The current border was established through a series of treaties negotiated between the two nations over centuries. These agreements determined territorial divisions and shaped how populations settled on either side of the line.
The border region connects indigenous communities from both nations, resulting in shared celebrations, culinary practices, and traditional customs.
Three main crossing points allow entry between the countries: La Quiaca-Villazón in the highlands, Aguas Blancas-Bermejo in the valley, and Profesor Salvador Mazza-Yacuiba in the flat Chaco area. Each crossing serves different regions and offers different landscape experiences.
The Yungas forest area spans across the border, with hundreds of plant and animal species moving freely between both countries. This green zone acts as a biological bridge where nature exists independent of political lines.
