The space of the County Belize is 8,867 mi².Belize is divided into four main geographic regions, including the relatively low Maya Mountains of the south that dominate all but the narrow coastal plain; the northern lowlands and its many rivers and streams; the flat and swampy coastal plain, and the almost countless cayes, islands and lagoons that fringe its Caribbean coastline.More than 50% of Belize is covered by tropical rain forest that's dissected by a network of rivers, mostly small in length. The largest and most significant river is the navigable Belize that stretches from the Guatemala border all the way to the Caribbean Sea.
