The largest amount of free flowing water in the world travels down the Amazon River. With its origins in the remote inter-Andean plateau the river flows eastwards towards the Atlantic Ocean. It drains an area spanning 40% of south America or over 6.5 million km2 (2.6 million mi2). The river flows through 8 countries and 1 overseas territory and is the source of 20% of all free flowing freshwater in the world. No bridges cross the river, mainly due to the dense forest growth along its banks.
