Los Arrayanes National Park, National park in Neuquén Province, Argentina.
Los Arrayanes National Park covers the 1,796-hectare Quetrihué Peninsula on the northern shore of Lake Nahuel Huapi. At its southern tip, a 20-hectare forest of arrayán trees (Luma apiculata) grows, with some individuals over 600 years old. A wooden path crosses this forest so visitors can see the cinnamon-coloured trunks.
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 arrayán is called quetri in Mapudungun, the Mapuche language, a name also given to the Quetrihué Peninsula where the forest stands. The park's arrayanes forest area is signposted to explain the growth stages of this slow-growing myrtle-family tree.
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 forest covers 20 hectares at the southern tip of the Quetrihué Peninsula, and some individuals are over 600 years old. A wooden path crosses it to keep visitors off the soil and roots, since the species grows slowly and young specimens were damaged by trampling.
