About this site
Ugly Island lies in the waters off Cabo Frio, a coastal town in Rio de Janeiro state known for the cold, nutrient-rich upwelling that draws divers along that stretch of the Brazilian coast. The site sits near the small islands and rocky outcrops scattered around the Cabo Frio peninsula, an area typically reached by boat from the town's harbor.
