Los Arrayanes National Park, National park in Neuquén Province, Argentina.
Los Arrayanes National Park sits on the Quetrihué Peninsula along Lake Nahuel Huapi and contains a dense forest of cinnamon-barked arrayán trees that grow up to 20 meters tall. The park covers a wooded peninsula with shoreline access and features walking trails winding through the tree canopy.
The park was established in 1971 to preserve one of the largest remaining concentrations of native arrayán trees, with some specimens exceeding 600 years old. This protected status safeguarded a woodland that has long been part of the regional landscape.
The name Quetrihué comes from Mapudungun, the language of the Mapuche people, and means "place of the arrayánes." This name reflects how indigenous communities understood and valued this woodland long before it became a protected area.
Visitors can reach the park on foot via a 12-kilometer trail from Villa La Angostura or by boat service that connects to the peninsula's southern point. Access depends on your preferred travel method, and both options provide different views of the woodland.
The arrayán trees feature a smooth, cold-to-touch bark in cinnamon color that feels unusual when handled. This distinctive quality makes walking through the forest a notably different sensory experience compared to other woodlands.
