Laguna Brava is a high-altitude lake situated within the Laguna Brava Provincial Reserve in the northwest of La Rioja Province, Argentina. Perched at approximately 4,230 meters (nearly 14,000 feet) above sea level, this remote and otherworldly body of water is surrounded by some of Argentina's highest peaks, including Mount Pissis (6,795 m), Bonete Chico (6,759 m), Bonete Grande (5,943 m), and the snow-capped Veladero (6,436 m) — all dormant volcanoes. The reserve itself encompasses 405,000 hectares and spans altitudes between 2,500 and 4,500 meters above sea level, with a Puna-Andean dry climate. The landscape is dramatic and largely uninhabited, with no permanent human settlements within the reserve boundaries. The lake sits within a wetland system that supports remarkable endemic birdlife, including Andean and Puna flamingos, making it as much a wildlife destination as a fishing one. Access to the reserve is only permitted through organized excursions led by authorized tour guides, and the journey from Villa Unión covers approximately 180 kilometers of asphalt and gravel road via RN 76.
