Laguna de Cotacotani is a stunning complex of high-altitude Andean lakes nestled within Parque Nacional Lauca in the comuna de Putre, Región de Arica y Parinacota, in northern Chile. Sitting at more than 4,500 meters above sea level in the puna altiplánica, this remarkable system of interconnected lagoons is framed by the snow-capped volcanic cones of Parinacota and Pomerape, creating one of the most visually dramatic fishing backdrops in South America. The lakes are fed by Andean snowmelt and glacial runoff from the cordillera and are hydrologically connected to bofedales — high-altitude wetlands — that in turn nourish the Río Lauca watershed. The turquoise waters contrast vividly against the surrounding volcanic rock formations and the white peaks of nearby volcanoes. The area is also part of the Reserva de la Biósfera Lauca, alongside Lago Chungará and other high-Andean ecosystems, underscoring its exceptional ecological significance. Access to the lagoons is via Ruta CH-11, the international highway connecting Chile to Bolivia, making the location reachable by vehicle from Putre and Arica.
