The reserve protects one of the few stable populations of guanacos in the central Chilean Andes.
The name 'Cipreses' refers to the Ciprés de la Cordillera, a species of conifer that can live for over 1,000 years.
The park's altitude ranges from approximately 1,000 to over 4,000 meters above sea level.
Archaeological evidence in the reserve includes rock art sites attributed to the ancestral inhabitants of the Teno and Cachapoal river basins.
The area functions as a vital water catchment zone for the Cachapoal River, supporting downstream agriculture in the O'Higgins region.
Reserva Nacional Rio de los Cipreses is a high-Andean protected area located in the O'Higgins region of Chile, encompassing over 36,000 hectares of rugged mountain terrain. The reserve serves as a critical habitat for the endangered Andean condor and the guanaco, a wild camelid native to the region. Its landscape is defined by the deep canyon of the Cipreses River, carved through volcanic rock and characterized by steep slopes and diverse microclimates. The flora includes high-altitude forests of Ciprés de la Cordillera (Austrocedrus chilensis) and various endemic shrubs adapted to the arid mountain environment. The reserve is managed by CONAF (Corporación Nacional Forestal) and features a series of marked trails ranging from short interpretive walks to more strenuous alpine treks. Visitors can access various sectors, including the Ranchillo entrance, which provides connectivity to primary trekking routes and observational sites. Geological features within the park include evidence of past glacial activity and unique rock formations visible throughout the central canyon area.
