It was formally declared a National Park in 2020 after previously operating as a National Reserve since 1982.
The park is home to the 'Río Clarillo' river, one of the few watercourses in the region that maintains water throughout the year.
It is considered a biodiversity hotspot due to its location at the meeting point of distinct ecological zones.
The park serves as a refuge for the 'Carpintero Pitío', a type of woodpecker endemic to the region.
The elevation within the park ranges from approximately 850 to 3,500 meters above sea level.
Río Clarillo National Park is the first national park located in the Santiago Metropolitan Region, elevated to this status in 2020. The park protects the sclerophyllous forest ecosystem and the Clarillo River watershed. It spans over 13,000 hectares, serving as a critical biological corridor for regional endemic species. Visitors access a network of hiking trails ranging from flat river-bank paths to steeper mountain ascents. The terrain is characterized by Mediterranean-type climate vegetation, including peumo, quillay, and litres trees. Wildlife observation includes the presence of culpeo foxes, mountain cats, and various raptors. The park serves as a vital water source for the surrounding Pirque agricultural valley. Conservation efforts focus on protecting the riparian flora that filters the river's water. Geologically, the park sits within the transition zone between the central valley and the high Andes.
