The "Llano Costero del Caribe" ("Caribbean Coastal Plain") is the largest of the plains in the Dominican Republic. Stretching north and east of Santo Domingo, it contains many sugar plantations in the savannahs that are common there. West of Santo Domingo its width is reduced to as it hugs the coast, finishing at the mouth of the Ocoa River. Another large plain is the "Plena de Azua" ("Azua Plain"), a very arid region in Azua Province. A few other small coastal plains are on the northern coast and in the Pedernales Peninsula.
