Raja de Manquehua is a remarkable geological formation located in the Coquimbo Region of central Chile. Known for its dramatic landscapes and tectonic significance, this site has recently been recognized as a Santuario de la Naturaleza (Nature Sanctuary) due to its unique geology, ecological importance, and cultural value. The term “raja” refers to the deep fissure or crack that splits the Cerro Manquehua, creating one of the most visually striking landmarks in the region.

Geologically, the raja de manquehua was formed by the Manquehua Fault, which stretches over 50 kilometers and has shaped the mountain’s distinctive structure. Over millennia, tectonic movements uplifted and fractured the rock, resulting in the dramatic fissure seen today. The area also contains unique rock formations, cliffs, and valleys, making it a fascinating destination for geologists, hikers, and nature enthusiasts interested in understanding the dynamic forces that shaped Chile’s landscape.

The sanctuary surrounding raja de manquehua covers more than 2,200 hectares of protected land. This area is home to a diverse range of flora and fauna, including endemic plant species adapted to the semi-arid climate and high-altitude conditions. Birds such as the Andean condor soar above the cliffs, while smaller mammals and reptiles inhabit the scrublands and rocky slopes. Visitors to the site can observe these species in their natural habitats while exploring the trails and viewpoints around the raja.
