Pasarelas del Parque Nacional Los Arrayanes


Despite being a small area (20 hectares), a large number of southern arrayanes trees (myrtles) are preserved here, giving rise to a beautiful and old forest with unique characteristics. In addition, there are forests of coihues, cypresses and ñires in this peninsula. This NP is located in the ecoregion of the Patagonian Forests.

The walkway in the Park

When you get off the catamaran or at the end of the trail, you come to a wooden walkway. It is an interactive tour that lasts about 30 minutes, and is easy to walk around. Unfortunately, it is not easy for people with reduced mobility or in wheelchairs. Something that some National Parks should start working on. At the end of the short walway (about 800 m), there is a café where you can have something to drink and eat.

In the interior of the peninsula there are two lagoons called Hua Huan and Patagua, where otters in danger of extinction live. You may see some birds like the carpenter pitío, the parrot cachaña, and the araucana remolinera.

The arrayán is the star tree of this PN. What is the arrayán? The arrayán, or myrtle, is an Argentine native tree, from the Andean-Patagonian region. Its great attraction lies in a cinnamon bark covered with white patches. If you touch it, it is cold and smooth, something very peculiar. It grows slowly on the banks of rivers and lakes. Some reach a height of 15 meters. It is a perennial tree that in summer is filled with numerous white flowers. The effect of the sun crossing the canopy of these trees in the forest is just magical.
