The lake is fed by glacial meltwater from the surrounding high Andean peaks.
It sits within a protected zone influenced by the geological history of the Maipo River basin.
The water levels fluctuate significantly between the winter snowmelt season and the arid summer months.
Laguna de los Patos is a high-altitude alpine lake located in the Cajón del Maipo region of the Andes. It sits at an elevation of approximately 2,800 meters above sea level. The site is a frequent stop for trekkers heading toward more remote mountain peaks in the San José de Maipo area. It is characterized by its volcanic soil and rocky surrounding terrain. The lake serves as a natural watering point for local mountain fauna. Access to the area is heavily dependent on weather conditions due to snow accumulation in winter.
The eastern shore provides a panoramic view of the lake reflecting the jagged peaks of the surrounding Andes.
Carry at least two liters of water, as the high altitude increases dehydration rates.
Use trekking poles to navigate the loose, rocky scree slopes surrounding the lake.
Pack layers, as wind speeds can cause temperatures to drop sharply within minutes even on sunny days.
Attempting to reach the site without a high-clearance vehicle or during the winter months when roads are blocked by snow.
Accessible primarily during the summer months; heavy snow often closes the area to vehicular traffic from May through October.
Practice Leave No Trace principles; carry all waste out as there are no trash facilities in this remote environment.
