Welcome to Parque Nacional Laguna Blanca
At 1275m above sea level and surrounded by striking volcanic deserts, Laguna Blanca is only 10m deep, an interior drainage lake that formed when lava flows dammed two small streams. Only 30km southwest of Zapala, the lake is too alkaline for fish, but hosts many bird species, including coots, ducks, grebes, upland geese, gulls and even a few flamingos. The 112.5-sq-km park primarily protects the habitat of the black-necked swan, a permanent resident. Birdlife is most abundant between November and March, and a short nature trail takes you across the steppe to the lakeshore from the visitors center.
