Río Grande serves as the inland anchor of this coastal landscape, where the Río Espíritu Santo flows toward the Atlantic Ocean. The topography shifts from the low-lying wetlands of Ciénaga La Picúa and the mangrove-lined Ensenada Comezón to the rising elevations of Cerro Bravo and Cerro El Faro. This area is characterized by a mix of traditional municipal centers and modern development, with civic landmarks like the Tribunal de Primera Instancia de Río Grande and the National University College - Río Grande appearing alongside established residential sectors. Coastal features like Punta Miquillo and Punta Percha define the shoreline, while smaller settlements such as Mini Mini, Vieques, and Honduras provide a detailed look at the local geography between the river and the sea.
