The Niagara Escarpment was created by ancient seas and is essentially a cliff that runs through Southern Ontario, from Niagara Falls to Tobermory and beyond. Not surprisingly, it is responsible for numerous waterfalls, the most famous of which is Niagara Falls. Any river or stream that originates above the escarpment and flows towards Lake Ontario or the Georgian Bay is going to fall off the escarpment at some point, resulting in a waterfall.

The Bruce Trail follows the escarpment from Tobermory all the way to Niagara falls, and passes by dozens of waterfalls.

If you travel from Tobermory to Niagara, some of the falls you will pass (in order) are:

You will also find Keefer Falls, Walters Falls, Hoggs Falls, Cataract Falls, Hilton Falls, Tiffany Falls, Upper Balls Falls and Louth Falls along the escarpment. Many of these waterfalls are reduced to trickles in mid or late summer.

The water that falls off the Niagara Escarpment by means of Eugenia Falls, Inglis Falls, Jones Falls, Indian Falls and Keefer Falls flows into Lake Huron. This means the water is destined to fall over the Niagara Escarpment a second time when it eventually empties into lake Ontario by means of Niagara Falls.
