Currently, Los Arrayanes National Park and Nahuel Huapi together form a single conservation and management unit. The park administration is located in the city of San Carlos de Bariloche, serving as the administrative and information center for both national parks.

Flora and Fauna

The Arrayanes: Ancient Trees

Arrayán trees are characterized by their cinnamon-colored bark and can live up to 650 years. They are endemic species of the region.

Iconic Species of the Park

The emblem of Los Arrayanes is the tree that gives it its name: the southern arrayán, also known as quetri, scientifically referred to as Luma apiculata. This tree or shrub thrives in very humid soils and is known for its slow growth. It can reach heights between 8 and 15 meters.

The southern arrayán has a distinctly twisted trunk, and its bark has a beautiful cinnamon color. As the tree matures, the bark peels off, revealing white spots, giving it a unique and attractive appearance. Its small, white flowers emit a pleasant fragrance.

This iconic tree, with its unique and enchanting appearance, is one of the main attractions of the park and one of the reasons why visitors are drawn to this magical place in the midst of nature.

Flora Species

In addition to the arrayán trees, the park is home to other plant species such as coihue, cypress of the Andes, and notro. Despite its modest size, Los Arrayanes Park hosts a magnificent display of southern arrayán trees (Luma apiculata), forming an extensive and ancient forest with unique characteristics. This concentration of arrayán trees is hard to find elsewhere in Chile and Argentina, making it an invaluable natural treasure.

The arrayán forest in the park captivates visitors with its ancient and towering trees. These southern arrayán specimens create a magical atmosphere with their cinnamon-colored bark and twisted trunks. It’s a captivating experience to stroll among these trees, immersing oneself in their beauty and feeling the energy they emanate.

In addition to the arrayáns, the forests of coihue and ñire trees flank the Quetrihué Peninsula, which extends like a giant tongue into the northern end of Lake Nahuel Huapi. These lush forests, with their leafy trees, frame and enhance the beauty of the park’s landscape. The coihue and ñire trees add diversity and contribute to the richness of the present flora in the area.

The combination of the impressive arrayán trees with the lush coihue and ñire forests creates an unparalleled landscape. The park offers nature enthusiasts a unique opportunity to immerse themselves in natural beauty and appreciate the variety of species that make up this unique ecosystem.

Typical Fauna

In the heart of the peninsula, there are two lagoons known as Hua Huan and Patagua, which serve as habitats for the southern river otter (huillín). This native otter species is endangered, and its presence in these lagoons is of great significance for conservation efforts. Observing the huillín in its natural habitat is a privilege and a unique experience for visitors.

Regarding birds, the park hosts a variety of noteworthy species. Among them is the Magellanic woodpecker, known for its distinctive drumming on tree trunks. The Austral parakeet is also present, with its colorful plumage and striking song. Another notable bird is the Thorn-tailed Rayadito, which inhabits the forests and offers a beautiful spectacle with its agile flight and melodious voice. Additionally, on nearby islands, you can find the freshwater subspecies of the imperial cormorant, a water bird species that seeks refuge in these natural environments.

The diversity of birds and the presence of the huillín in the protected area of Los Arrayanes provide birdwatchers and wildlife enthusiasts with a great opportunity to enjoy and appreciate the beauty of these species in their natural habitat.
