About this site
The Sunken Reef lies off Antofagasta, on Chile's northern coast where the Atacama Desert meets the Pacific. The area is shaped by the cold, nutrient-rich waters of the Humboldt Current, which typically carve the rocky reef structures found along this stretch of coastline. This particular site is rated an advanced dive. Conditions along the Antofagasta coast tend to reflect the open Pacific exposure typical of northern Chile, with boat access usually required to reach offshore reef formations like this one.
