The surface area of the Amazon River Basin covers 7,500,000 sq. km (2,900,000 sq. mi.), draining much of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname and Venezuela. It is covered by the largest rainforest in the world. The headwaters of the Mantaro River in Peru are the Amazon’s most distant source. Its mouth on the South Atlantic Ocean is located in Brazil. The Amazon also holds records for the world’s greatest river flow and the largest tidal bore in the Americas.
