The Coro region is the hilly and semi-mountainous area in northwest Venezuela, north of the Mérida Andes and east of the Maracaibo Basin, extending north to the Caribbean coast. It consists mostly of east-west running ridges, with the exception of the Sierra de Siruma which run north-south. The coastal plain of the region contains Venezuela’s only desert, the Médanos de Coro (the Coro Dunes), on the Paraguaná peninsula. The Coro region is one of the ten geographical regions into which Venezuela can be divided. Because the two major depression valleys are the Falcón and the Lara, the mountains are sometimes called the Falcón-Lara ranges. The geographic region covers all of Falcón State, half of Lara State and Yaracuy State, and small percentages of Zulia State and Carabobo State.
