Llanos de Challe National Park

Llanos de Challe National Park is located on the Pacific coast of the Atacama Region, Chile. The nearly-rainless park's mountains are moistened by the Camanchaca, creating a fog and mist-fed ecosystem called lomas (Spanish for "hills"). The park is one of the southernmost locations of the lomas which are scattered along the coastal desert from northern Chile to northern Peru. The highest elevation in the park is Cerro Negro at 950 m.
