The Niagara Whirlpool is a natural whirlpool along the Niagara River located along the Canada–US border between New York and Ontario. The whirlpool is located in the Niagara Gorge, downstream from Niagara Falls.
It is estimated that the whirlpool formed approximately 4,200 years ago. Average depth of Niagara whirlpool is 125 feet (38 m). The Niagara whirlpool formed approximately 4,200 years ago by the upstream erosion of the Niagara Escarpment by the Niagara River. The rapid flow of water exiting the Niagara Gorge results in turbulent swirling of the river.
The whirlpool naturally spins in a counterclockwise motion during normal flow. When more water from the river is diverted to the surrounding hydroelectric power plants, the flow often reverses.
There are two state/provincial parks located alongside the whirlpool. The Whirlpool State Park (on the US Side) and Niagara Glen Nature Reserve (in the Canadian side).
The Whirlpool Aero Car Whirlpool Aero Car suspended between two Canadian points, crosses the Niagara Whirlpool during the trip. The passengers can enjoy the spectacular views of the swirling Niagara Whirlpool during the trip.
