Some people have gone so far as to claim that Hamilton is 'The Waterfall Capital of the World.' To be honest, this is debatable. For example, there is strong competition coming from Ithaca, NY, just a few hundred kilometres to the east.

You should also be aware that many of the waterfalls in Hamilton are very small, and/or dry up for much of the year. They are still waterfalls, and great photos can be made at the right time of year. But once you get past the best 2 or 3 dozen, many people will be disappointed. (eg. see Dyment Falls or Erland Falls or West Iroquoia Falls). Still, there is nowhere else in Ontario with this concentration of waterfalls, giving it good bang for your buck.
