Near Paso Alto Coyhaique on the Argentine border, this 181-hectare wetland reserve hosts diverse birdlife, including black-neck swans, coots and grebes. It's an ecological transition zone from southern beech forest to semiarid steppe. Orchids abound. A short hiking trail goes to Laguna El Toro while a longer loop flanks the northern edge of Laguna Escondida. Near the entrance there's a self-guided nature trail (1km) and picnic area.
While the park lacks regular public transportation, Coyhaique's branch of Conaf may be able to offer suggestions for getting there.
