Cordillera Occidental, Mountain range along Chile-Bolivia border
The Cordillera Occidental is a mountain range spanning the Chile-Bolivia border, featuring active volcanic peaks and sweeping high-altitude plateaus. The terrain consists of rocky slopes, salt flats, and sparse vegetation adapted to the thin mountain air above 13,000 feet (4,000 meters).
This range has served as a border region between the two nations for centuries, marked by territorial disputes. Following a major conflict in the late 1800s, Bolivia lost the territory to its west, leaving this chain as the international boundary.
Indigenous Andean peoples have lived in these highlands for centuries, developing deep knowledge of the terrain and its wildlife. Their settlements dot the high plateaus, where traditional ways of raising llamas and alpacas continue alongside the natural rhythms of mountain life.
Visiting this range requires high-clearance vehicles and careful planning, as roads are rough and scattered across remote areas. Stock up on fuel and supplies before heading out, as services are few and far between in the mountain region.
The northern section protects rare high-altitude forests of queñua trees, among the highest growing trees on earth. These forests also shelter wild vicuñas that roam freely across the slopes, making the area a refuge for remarkable wildlife adapted to extreme conditions.
