Cerro Chena hosts one of the most important Incan Pukaras (fortresses) identified in the central region of Chile.
The archaeological complex dates back to the late period of the Inca occupation in the Mapocho valley (approx. 1470-1540 AD).
Archaeological studies have identified specialized rooms for food storage (qollqas) and administrative activity within the stone foundations.
The park restoration project emphasizes the recovery of native flora to combat erosion and promote local biodiversity.
The name 'Chena' is linked to local indigenous toponymy, reflecting the area's history of habitation before the arrival of the Incas.
The site was historically utilized as a strategic lookout point due to its commanding elevation over the surrounding valley.
Cerro Chena is a significant archaeological site and urban park located in San Bernardo, serving as a primary node for the Metropolitan Regional Park system. The site features an Incan Pukara, a fortified hilltop structure that functioned as an administrative and defensive center for the Inca Empire's southern reach. Excavations have uncovered circular and rectangular stone structures, including dwellings and ceremonial platforms. The park spans varied topography offering panoramic views of the Santiago valley and the Andes mountains. Native sclerophyllous vegetation, such as peumo and quillay, has been extensively replanted during recent restoration efforts. The site is recognized for its historical duality, bridging pre-Hispanic history with contemporary public recreation space. Trails are integrated into the hillside, facilitating access to both the archaeological zones and higher observation points.
The highest summit point provides a 360-degree view, including the Pukara ruins with the Andes mountains as a backdrop.
Bring a windbreaker, as the hilltop is frequently exposed to strong breezes.
Apply high-factor sunscreen, as there is very limited natural shade along the ascent.
Carry at least one liter of water, as there are no potable water stations inside the park.
Do not attempt to climb off-trail, as the rocky terrain is unstable and risks disturbing unexcavated ruins.
The park may close during periods of extreme weather conditions or high forest fire risk during summer months.
Stick strictly to marked trails to avoid damaging fragile archaeological remains and native vegetation; leave no trace.
