Cerro Renca, Mountain summit in Santiago Region, Chile

Cerro Renca is a summit on the northern edge of Santiago's urban area, reaching around 905 meters above sea level. It rises noticeably above the surrounding neighborhoods and connects through trails to nearby peaks such as Cerro Colorado and Puntilla Lo Ruiz.

A white cross was installed near the summit in 1987, linked to Pope John Paul II's visit to Chile, and fireworks were launched from it at New Year under the Municipality of Renca. In 2010 the sign "Renca la lleva" went up on the southern slope; in December 2016 mayor Claudio Castro had "la lleva" removed, leaving only "Renca". In 2014 the hill placed second in the Cerros Isla competition, which Cerro Chena won.

The white cross near the summit was installed in 1987, and the Municipality of Renca launched New Year fireworks from it, not from gatherings of residents watching the city below. In 2010 the hill's southern slope received white letters reading "Renca la lleva"; in December 2016 mayor Claudio Castro had "la lleva" removed, leaving only "Renca", arguing the slogan stigmatised the commune.

Access to the summit is via a gravel road from Quilicura on the northern side and a paved road from Renca on the south. A new entrance through Cerro Colorado opened in November 2024. Slopes can reach about 65 degrees, and shallow ravines may carry loose sediment during intense rainfall.

On a clear day, both the Andes to the east and the coastal range to the west are visible from the top at the same time. Few spots within Santiago's city limits offer this kind of view of the two mountain systems framing the valley.
