The Niagara Whirlpool is a powerful natural phenomenon formed by the Niagara River's sharp bend, creating a massive vortex, best viewed from above. It is easily accessible via the Niagara Parkway for free, or for a more immersive experience, ride the historic Whirlpool Aero Car (approximately CAD $17-20 per adult, operating seasonally from spring to late fall, typically April/May to November). A visit typically lasts 15-30 minutes for a view, or 30-60 minutes if including the Aero Car ride, and can be enjoyed both solo or as part of a guided tour of the wider Niagara Falls area. While the whirlpool is present year-round, winter viewing may offer different aesthetics, but some facilities like the Aero Car will be closed.
