Adventure Tourism. The Niagara River collects all the water from the Great Lakes which amounts to about 20% of the world's fresh water. Over the past 12,000 years, the turbulent currents of the immensely powerful Niagara Falls have carved out a 7-mile (11km) gorge on the lower Niagara. Hundreds of thousands of gallons of water flow over the Falls every minute and as that water enters the narrow rock gorge, it is compressed into the rapids that create our whitewater playground.Why Jet Boats?Safety. Power. Again, Safety. Whirlpool Jet Boat Tours operates a fleet of custom-built vessels designed to the latest innovations in marine technology. Our boats use a triple turbo diesel water jet system for both propulsion and steering, a design that creates incredible reliability and safety in the turbulent whitewater rapids. This is why we have been able to create and sustain our exemplary safety record.
