From the parking lot, take the little path at the right end of the park, go down on by the little trail, pass the first sector of "La croix Saint-Anne". Once at the base, walk along to the very right of the cliff, the path should continue through the trees. You will quickly find a big boulder. Let it on your right and take left to go in the direction of the Saguenay river. Keep going, you should see a sign showing both directions for the top and the base of the cliff. The top is obvious. For the base, go left at the sign, you should have some easy unclimb with fixed ropes. You should see a pack of very old american cars, let them on your left and keep going. You have to pass under some boulders to get to the cliff. Here you are.
