Niagara Falls are a stunning display of mother nature’s beauty and force. The falls are actually composed of three waterfalls, the America Falls, the Bridal Veil Falls, and the Horseshoe Falls. Horseshoe Falls is the largest of the three, with a vertical drop of over 165-ft. Together, the three waterfalls produce the highest flow rate of any waterfall on earth. Nearly 700,000 gallons of water travel down Niagara Falls every second. For this reason, Niagara falls is also an important source of hydroelectricity. The falls are just a short drive from Toronto and straddle the border between Ontario, Canada, and New York, USA, but don’t think you can cross the border so easily; you’ll still need to present a valid passport and go through customs. In fact, in 2012, when Nik Wallenda crossed Niagara Falls by tightrope, he was required to carry his passport and present it on entry to the Canadian side of the falls. Viewing platforms and a ferry offer spectacular views of the falls at a safe distance.
