Puerto Rico is a small town in Pando, northern Bolivia, with an associated airport. It is located in the Manuripi-Heath Amazonian Wildlife National Reserve. Founded on May 18, 1890, it was the first departamental capital, before Cobija. It is located at the Confluence of the Manuripi and Tahuamanu Rivers. Every year, in the month of June, the International Recreational Fishing Championship of Puerto Rico takes place at the river confluence, where the two rivers combine to form the river the River Orthon. This river then flows 410 km before it converges with the River Beni.
