Cibao

Cibao, usually referred as "El Cibao", is a region of the Dominican Republic located at the northern part of the country. As of 2009 the Cibao has a population of 5,622,378 making it the most populous region in the country.

The word Cibao, meaning "place where rocks abound", was a native name for the island, although the Spanish used it during the Spanish conquest to refer to the rich and fertile valley between the Central and Septentrional mountain ranges.
