Sherman Falls sits pretty right in the middle of a pretty town called Ancaster. The flow is always good here because its comes from the Ancaster creek where it flows over the Niagara Escarpment.
If you drive, just park on the side of the road (everyone does it) where Old Dundas meets Lions Club road. Sherman is on your left. Just a hop, skip and a jump and you're into a lovely forested cove with tall aspens and birch trees.
If you are fortunate enough to live in Ancaster, its about a kilometer along Old Dundas road, not far from the Ancaster Mill Restaurant. Canterbury Falls is in the area as well. There's a hike up above the Sherman Falls as well, but will have to return for that sometime soon.
Last year some helpers from the Iroquois Bruce trail club replaced the 25 year old bridge that ran across Ancaster Creek with a new one made of Douglas Fir. It only took them a couple of days to construct it, but members of club volunteer their time and materials to projects around the city to help maintain the Bruce trail and others. Some of them have ties to Dofasco so they are able to bring tools and equipment in the effort.
Sherman Falls is 17 metres high and 8 metres across. You'll find excellent directions to get here if you click this:
