Located in Nahuel Huapi, Argentina’s oldest national park, is this gorgeous hiking trail known as Sendero de Los Arrayanes. The photo was taking by Flickr user Adry, and she says it winds from Puerto Pañuelo to Lago Moreno.

At this particular spot, with the trees branches arched over, the trail takes on the shape of an eye.

Established in 1934, the Nahuel Huapi National Park surrounds Nahuel Huapi Lake in the foothills of the Patagonian Andes. The largest of the national parks in the region, it has an area of 7,050 km2 (2,720 sq mi), or nearly 2 million acres. [Source]
