Pitahaya is a barrio located in Arroyo, a municipality on the southeastern coast of Puerto Rico. The barrio spans approximately 8.26 square kilometers and sits within the broader Caribbean context of the eastern coastal region, characterized by tropical climate and proximity to the Caribbean Sea. As part of Arroyo, Pitahaya benefits from the municipality's geographic position between the mountainous interior and the coastal plains that define this part of the island.

The landscape of Pitahaya reflects the typical terrain of southeastern Puerto Rico, with a mix of coastal plain and gradually rising terrain moving inland. Like much of rural Arroyo, the barrio is primarily characterized by open land and dispersed settlement patterns rather than dense urban development. The vegetation and climate are consistent with the tropical dry forest zone that dominates this region, making it suitable for a mix of agricultural pursuits and low-density residential use.

Property in Pitahaya tends toward larger plots and rural parcels rather than urban subdivisions. Residents and landowners in the barrio are likely to hold property used for agriculture, livestock, or conservation, alongside traditional residential holdings. The absence of major commercial corridors or high-density housing distinguishes Pitahaya from more urbanized barrios in the municipality, preserving its rural character while remaining accessible to Arroyo's services and the broader infrastructure of the southeastern coast.

Property ownership and lot configurations in Pitahaya are documented through Puerto Rico's cadastral system, and Propieda maintains accessible records for all parcels registered in this barrio.
