Cerro Ñielol, Natural monument mountain in Temuco, Chile

Cerro Ñielol is a protected natural monument in Temuco, Chile, rising between 115 and 335 meters above sea level. Its 89 hectares hold one of the last remnants of Valdivian forest in the Intermediate Depression, with species such as ñirre, olivillo, copihue, raulí, roble and canelo. A paved road climbs to viewpoints and the La Cumbre del Ñielol restaurant.

The mountain received protected status in 1987 through a government decree after conservation groups advocated for preserving its forest. This action recognized the ecological importance of the site for the region.

The Mapuche called the hill Nge-lol or Ge-lol and used it for ceremonial worship and for timber to build rucas. At the spot where the 1881 parliament was held stands a ceremonial center with a chemamull, an anthropomorphic wooden totem, named La Patagua del Armisticio.

The site is most accessible during daylight hours, with the main entrance located about seven blocks from the city center. Visitors should bring comfortable walking shoes and water since trails wind through steep forested sections.

The summit holds a ceremonial site with a chemamull, an anthropomorphic wooden totem, called La Patagua del Armisticio, marking where Mapuche representatives and the Chilean Army signed a peace treaty on 24 February 1881. The hill was also the territory of the lonco Ralum-Koyam.
