Geography of the Dominican Republic
The Cibao Valley is the largest and most important valley of the country. This long valley goes from Northern Haiti, where is called Plaine du Nord, to Samaná Bay. It can be divided in two parts: the northwestern part is the Yaque del Norte Valley (or Línea Noroeste) and the eastern Yuna Valley (or Vega Real, English: Royal Valley). The Vega Real has the best soils of the country; the population density is high.
