Salinas sits along the southern coast of the Island of Puerto Rico, where the waters of Bahía de Rincón meet the Caribbean Sea. This coastal landscape is defined by its intricate shoreline, featuring the Marina de Salinas and numerous offshore keys such as Cayos de Ratones and Cayo Morrillo. The town is situated on a low coastal plain between the mouths of Rio Nigua and Rio Jueyes, with the prominent elevation of Cerro Modesto rising to the north. Settlement patterns include the residential clusters of Playita, Las Ochenta, and Coco, connected by the established PR-1 and PR-3 routes. The geography here is a mix of mangrove-lined inlets like Mar Negro and coastal points such as Punta Salinas, reflecting a region tied closely to maritime activity and river drainage systems.
