Los Arrayanes National Park is a national park of Argentina with an area of 17.53 square kilometres. It covers the Quetrihué Peninsula on the shore of the Nahuel Huapi Lake in the province of Neuquén, 3 km from Villa la Angostura.
Even though arrayán trees can be seen on the way to the end of the peninsula, the forest of 300-year-old arrayanes covers 0.2 km2 of the southern point, with individuals of over 600 years. The forest can be reached by boat from different points of the Nahuel Huapi lake, or a 12 km path from the beginning of the park at the port of Villa La Angostura. This path, full of ups and downs, is also popularly done by mountain bike.
