Mopan River
 The Mopan River is a river in Guatemala and the Cayo district in western Belize near the border with Guatemala. The Mopan River discharges to the Belize River as the Mopan merges with the Macal River; the Belize River in turn terminates at the Caribbean Sea. The Belize River/Mopan River Catchment contains over 45 percent of the human population of Belize. A hand-cranked ferry boat conveys visitors to the Xunantunich site across the turbid Mopan River.
