Piedras Blancas is a barrio in Aguada, located on the northwestern coast of Puerto Rico in the region known as the Porta del Caribe. The barrio spans approximately 7.26 square kilometers and represents one of Aguada's interior neighborhoods, positioned inland from the municipality's coastal areas. Within the broader geography of northwestern Puerto Rico, Aguada sits between Moca to the south and Isabela to the north, placing Piedras Blancas in an area marked by transitional terrain between coastal plains and the foothills that characterize the region's interior.

The landscape of Piedras Blancas reflects the mixed topography typical of inland northwestern barrios, with a combination of relatively flat agricultural areas and gentle elevations. This terrain has historically supported both farming activity and low-density residential settlement. The barrio's name references the distinctive white or light-colored stone formations found throughout parts of Aguada's interior, a geological feature that has shaped land use patterns for centuries. Like much of the inland areas in this region, Piedras Blancas experiences the tropical climate characteristic of northwestern Puerto Rico, with warm temperatures year-round and significant rainfall that supports vegetation growth.
