Guayaramer�n is a city within the Bolivian Beni Department. It is the capital of the Guayaramer�n Municipality in the Vaca D�ez Province. Guayaramer�n is located on the west side of the Mamor� River, facing the Brazilian city of Guajar�-Mirim. It is a port in which there is a permanent port of the Bolivian Navy. The city has a small airport, served by three local airlines: AeroCon (Aero Comercial Oriente Norte), TAM (Transporte A�reo Militar) and Amaszonas.
Facing the city there is the small island of Su�rez, or Guajar�-Mirim as it is called by the Brazilian government. The island is disputed by both countries, and treaties in 1867, 1877 and 1958 have failed to clear the matter.
