Niagara River, International river between Ontario and New York, Canada and United States
The Niagara River connects Lake Erie to Lake Ontario and flows for most of its length along the international border between Ontario and New York. Several bridges cross the water, and large power plants on both banks use the current to generate electricity.
The French built Fort Niagara at the mouth in 1678 to control trade routes and military movements. During the 19th century, engineers began harnessing the water for power, which shaped how industry developed on both sides.
The river's name originates from the Iroquoian-speaking Neutral tribe who inhabited the Niagara Peninsula and maintained peace between surrounding indigenous nations.
Several viewpoints along the banks let you watch the rapids and gorge, especially upstream and downstream from the falls. Many spots are easy to reach, but be aware of strong currents that make swimming and boating risky.
A natural whirlpool forms in the gorge where the water rushes through narrow rapids and then suddenly turns northeast at a sharp angle. This spot draws many visitors who want to see the spinning water up close.
