The Montmorency Falls are the highest waterfalls in Canada. To get to the top, one can take the gondola, or climb the 467 stairs straight up the side of the hill.
The 467 stairs to the top of Monmorency Falls are built precariously up the side of a steep slope and it can be a little frightening to look down, but it's well worth the climb.
