The Barima River is a tributary of the Orinoco River, entering from the Atlantic Ocean. It originates from the Imataka Mountains in Guyana, flowing for approximately before entering Venezuela about from its mouth. Features Early recorded explorations of the Barima were made by Robert Hermann Schomburgk, which was mapped as far as the tributary Rocky River. The head of the Barima rises in a steep gorge of the Imataka mountains, above sea level. Near the Duquari Creek, the Arawatta Rock, a distinct large granite rock, is located. Settlements Mabaruma, Koriabo, and Morawhanna are Barima-Waini Region communities on the Barima River.
