Espejo Lagoon is one of the most outstanding natural attractions of the Araucanía Andina, located in the Sierra Nevada area, commune of Lonquimay. It sits in a stunning mountain setting where native forests, mountains, waterways, waterfalls, rock formations and glacial landscapes all converge.
One of its main draws is the view of the Sierra Nevada and its glaciers, which accompany much of the route. On clear days, the lagoon's still waters can reflect the surrounding mountains, giving rise to its characteristic name, 'Mirror Lagoon.'
The hike offers a mountain trekking experience and a connection with nature, in a largely untouched setting of great scenic value.
