Posted on October 30, 2025

Introduction to Los Alerces National Park

Los Alerces National Park is an important conservation area and a captivating destination located in the Chubut Province of Argentina. Established in 1937, the park spans approximately 2,630 square kilometers and is celebrated for its awe-inspiring landscapes, which include lush forests, pristine lakes, and majestic mountain ranges. The park derives its name from the ancient alerce trees (*Fitzroya cupressoides*), a key element of this unique ecosystem.

Ecological Significance

The ecological significance of Los Alerces National Park is profound. One of the park’s defining characteristics is its diverse array of flora and fauna.
