Rao Grande is a small barrio located in the northeastern municipality of Río Grande, in the central-eastern region of the island. The barrio comprises approximately 0.51 square kilometers and represents one of several neighborhoods within Río Grande's wider administrative area. This northeastern region of the island features a tropical climate with consistent warm temperatures year-round and elevated rainfall, characteristics that have historically shaped both land use and agricultural patterns across the municipality.

The barrio's geography and name suggest a landscape oriented toward rural or semi-rural development, typical of many inland neighborhoods in Río Grande. Rather than the coastal infrastructure found in some parts of the municipality, Rao Grande likely contains mixed residential and agricultural land use. Properties in this size range tend to feature smaller lots typical of traditional Puerto Rican rural settlement patterns, with land parcels reflecting historical inheritance divisions and subsistence-based family holdings.

Currently, cadastral records maintained by CRIM (Centro de Recaudación de Ingresos Municipales) show zero recorded parcels for Rao Grande, which may indicate either very recent parcellation changes, incomplete digitization of historical property records, or that the barrio comprises unregistered or aggregated landholdings.
