Pedernales is a barrio located in the southwestern municipality of Cabo Rojo, positioned in the western region of Puerto Rico near the Caribbean coast. The name Pedernales, meaning flint or hard stone, reflects the geological character of this area. Within Cabo Rojo's municipal geography, Pedernales occupies approximately 19.27 square kilometers and represents one of the municipality's less densely populated rural territories.

The landscape of Pedernales is predominantly rural and agricultural, characteristic of the interior and southern portions of Cabo Rojo away from the immediate coastal development. The terrain in this part of western Puerto Rico tends toward rolling hills with limestone formations and scattered vegetation typical of the southwestern climate zone. Property in Pedernales reflects this rural composition, with holdings generally consisting of larger parcels suited to agricultural use, livestock operations, or conservation rather than dense residential subdivisions. Development here remains sparse and dispersed, making it distinct from the more urbanized areas of Cabo Rojo municipality.

Given its distance from major commercial centers and coastal tourist corridors, Pedernales has maintained a primarily agricultural and residential character. Property owners in this barrio typically manage acreage rather than small urban lots, and land values remain grounded in productive and strategic use rather than speculative development. The barrio serves residents with deeper roots in the area and those seeking rural property with greater land area than is available in more developed zones.
