Straddling the US-Canadian border, Niagara Falls is within reach of Toronto - and well worth it. The three falls combined, the Horseshoe Falls, the American Falls and the Bridal Veil Falls, form the highest flow rate of any waterfall in the world (around 2,400 m3 per second). Once you've seen the Falls (take a Maid of the Mist tour), explore the theme park-esque town that lives off the natural wonder's tourist appeal.
