Nevado Tres Cruces National Park (Spanish pronunciation: [neˈβaðo tɾes ˈkɾuses]) is a national park located in the Atacama Region of Chile, east of Copiapó. It includes Laguna Santa Rosa, Laguna del Negro Francisco, and a part of the Salar de Maricunga. The park is divided into two zones, the northern zone encompassing the southern portion of Salar de Maricunga and Laguna Santa Rosa, and the southern area the Laguna del Negro Francisco. The park is named after Nevado Tres Cruces, which dominates the landscape of the area. The park is managed by the Corporación Nacional Forestal (National Forest Corporation; CONAF), which offers two refuges in the area: one at the south of Negro Francisco Lagoon and other at the west of Santa Rosa Lagoon. The park is open from October to April.
