Great Falls (also known as Grindstone Falls) is located on the Grindstone Creek just off Mill Street, in Waterdown.
Until 1912, Grindstone Creek was used as a source of power for a sawmill at the base of Great Falls. The waterfall flows year round and a viewing platform has since been built, as well as a parking lot for visitors.
According to the City of Waterfalls website, Great Falls is one of the several Hamilton area waterfalls to be featured regularly in postcards.
Great Falls is also accessible via the Bruce Trail.
