Rao Arriba is a barrio located in Añasco, a municipality on the western coast of Puerto Rico in the Mona Passage region. The barrio occupies approximately 3.50 square kilometers and sits within Añasco's interior territory, positioned inland from the coastal areas that define much of the municipality's geography. This positioning places Rao Arriba in a transition zone between the lowland coastal plains and the slightly elevated terrain that characterizes the western interior of the island.

The landscape in Rao Arriba reflects the broader topography of western Puerto Rico, with a mix of subtropical vegetation typical to the region. The barrio's name suggests elevation relative to other areas, a common naming convention in Puerto Rican geography where "Arriba" indicates upper or higher ground. This terrain influences land use patterns and property development patterns across the barrio, creating a landscape that blends rural character with scattered residential settlement.
