Laguna Miscanti is a striking brackish lake perched at 4,140 meters (13,580 feet) above sea level on the Altiplano of Chile's Antofagasta Region, nestled among the towering volcanoes of the Central Andes. Shaped like an arrowhead with a distinctive peninsula jutting from its northern shore, the lake covers approximately 13.5 square kilometers (5.2 sq mi) and is fed primarily by groundwater and springs, with no permanent surface inflows or outflows. The lake sits within the Reserva Nacional Los Flamencos, southeast of the Salar de Atacama, and is separated from the smaller Laguna Miñiques to the south by an ancient lava flow from the Miñiques volcanic complex. The surrounding landscape is defined by golden puna grasses, snow-capped volcanic peaks, and crystal-clear high-altitude air. The closest towns are Socaire, approximately 20 km away, and San Pedro de Atacama, roughly 90 km to the northwest. The extreme elevation, volcanic geology, and brackish water chemistry make this one of the most unusual and remote fishing environments in South America.
