Alto Biobío National Reserve

Alto Biobio National Reserve is a protected area in the Andes that spans mountains and high-altitude valleys with mixed forests. The landscape is shaped by rivers and streams flowing through steep gorges and open plateaus.

The reserve was created in 1912 to protect the Araucaria forests and mountain ecosystems from logging and exploitation. This decision came as concern grew about forest loss across the region.

Pewenche communities have lived here for centuries, relying on the Araucaria trees as a food source and spiritual center of their world. Their traditions shape how the land is used and understood today.

The reserve can be reached through various entry points, each offering trails for different skill levels from easy walks to challenging climbs. Basic camping and overnight facilities are available for visitors planning multi-day trips.

The reserve straddles the border with Argentina and forms part of a larger biosphere reserve that spans both nations. This cross-border location makes it a rare example of ecological protection that ignores political boundaries.
