Peñón de Entrerríos, Natural rock formation in Antioquia, Colombia.

Peñón de Entrerríos is a granite monolith 72 metres high above ground level, located entirely within the municipality of Entrerríos, Antioquia. It is part of the Antioquian batholith, the same underground rock body that includes the Piedra del Peñol de Guatapé. Its summit is narrow, with a Christ statue and a statue of the Virgin of Mercies on one of its ledges.

The rock formation emerged from tectonic movements and volcanic activity during the Andes mountain building process over geological periods. These processes created the distinctive structures that shape Antioquia's landscape today.

The rock is Entrerríos's most recognisable symbol and, with the nearby Pontezuela stream and Ríogrande II reservoir, forms one of the emblematic landscapes of Antioquia's Norte region. A Christ statue on the summit and a Virgin of Mercies statue on a rock ledge express the municipality's faith. Legends told about the caves at its base feed local folklore.

You can reach the site via marked hiking trails that vary in difficulty and length depending on your starting point. Plan adequate time and check local weather conditions before visiting.

At the base of the monolith are deep caves that remain practically unexplored, and local myths and legends have grown around them, feeding the folklore of the area. The rock is the most recognisable symbol of Entrerríos, together with the nearby Pontezuela stream and the Ríogrande II reservoir.
