This boat takes tourists up and down the Amazon. The Amazon is the second longest river in the world, running from the Atlantic Ocean far up into South America. Some places where the Amazon goes have few roads. Some have no roads. The Amazon is actually like a road, a great water highway, that goes up through the jungle. A trip on the Amazon is an unforgettable experience if you ever have the opportunity. You probably know about the dangerous piranhas in the water, but did you know that they cannot live at high altitudes? So, if the river goes high enough, you will be safe from them.
