The Amazon River is so vast that is sometimes called The River Sea. During the rainy season the Amazon can be up to 24.8 miles wide. It is so wide that it is not always possible to see across it to the other side. It is navigable all year round, by sea-going vessels as far up as the port of Iquitos in [[Peru]]. | The Amazon River is so vast that is sometimes called The River Sea.
