Rao Abajo is a barrio located in Ceiba, a municipality on the northeastern coast of Puerto Rico in the Noreste region. The barrio spans approximately 20.78 square kilometers and occupies an inland position within Ceiba's territorial division. Its geography reflects the transition zone between the coastal lowlands and the interior terrain characteristic of this part of the island, where tropical vegetation and moderate elevation changes define the landscape. The climate in this region is tropical and humid, with consistent rainfall that supports dense vegetation typical of northeastern Puerto Rico.

The barrio's landscape is predominantly rural to suburban in character, with development patterns reflecting traditional settlement patterns in the interior of Ceiba. Much of the area consists of undeveloped land interspersed with residential properties, agricultural plots, and natural forest cover. Property in Rao Abajo tends toward larger land parcels rather than dense urban subdivision, making it suitable for landowners seeking space for agricultural use, residential compounds, or land investment. The terrain and vegetation support small-scale farming and forestry activities historically common in inland barrios of this municipality.

Access to Rao Abajo is provided by local roads connecting to Ceiba's main transportation corridors, linking residents to the municipality's more developed coastal zones and to regional routes serving the broader northeastern sector of the island. The barrio remains relatively isolated from major urban centers, preserving its rural character while maintaining connection to Ceiba's municipal services and infrastructure.

Property records and cadastral information for parcels within Rao Abajo are available through Propieda's database of CRIM land records.

Ceiba: Ceiba, on Puerto Rico's east coast, underwent transformation after the Roosevelt Roads Naval Station closure. The former base area offers development opportunities, while established areas provide residential options near the Ceiba ferry terminal serving Vieques and Culebra. Natural attractions include beaches and the nearby rainforest.
