The Niagara Escarpment is a long escarpment running through southern and central Ontario, Canada.
In February 1990, the Niagara Escarpment was designated a World Biosphere Reserve by UNESCO, making it one of 12 in Canada.
Niagara Falls is formed by the Niagara River flowing over the escarpment, and the Bruce Trail runs the length of the escarpment. The Welland Canal allows ships to traverse the Escarpment between Lake Erie and Lake Ontario.
