Several hundred million years ago, during the Paleozoic era, the entire Québec City area was located on a continental margin. The waterfall is a remnant of this ancient period—a fault over which the Montmorency River rushes..

"There are staircases that allow visitors to view the falls from several different perspectives. A suspension bridge over the crest of the falls provides access to both sides of the park. There is also an aerial tram (Funitel) that carries passengers between the base and the top of the falls. In the summer the park hosts an international fireworks competition with the falls as a backdrop.

During summer months, the falls give off a yellow glow due to high iron content in the waterbed." -Wikipedia
