-Rio Clarillo National Reserve

This reserve is located in the central pre-Cordillera area, some 45 kilometers southeast of Santiago, in the Pirque municipality. Its terrain covers 13,185 hectares, with altitudes varying between 850 and 3,500 meters above sea level.
Its main attraction is the Rio Clarillo, a stream providing drinking water to the nearby municipalities of Pirque and Puente Alto, and forming the main axis of the Reserve.
This Reserve is notable as the last outpost of the (hard-leafed) sclerophilous forest in the central area. This type of forest is formed mainly by species such as peumo, litre, lun and quillayes.

Among birds inhabiting the area are specially found the eared dove, a bird which in the Metropolitan Region is in danger of extinction and whose only refuge is in this reserve. Another endangered species is the Chilean iguana, that looks somewhat like an "overfed" lizard.

The Reserve is equipped for picnicking, and has excursions accompanied by interpreters and an Environmental Information Center. The Park has no authorized campsites, and camping is only possible here with special permission from the Conaf.
The local climate consists of a 7-month dry period, with rainfall occurring in the winter months. January temperature is 24°Celsius and in July 11°Celsius.

Also among its attractions are the Excursion Pathways:
