As you reach the spot this is the view you are presented with.  Looking around for a few seconds you are at a bit of a loss as to how to get down the bluff line to get underneath and get a good view of the falls and check out the "cave".

On the opposite side of the falls is a smaller overhang you have to crouch down and waddle though to get to a shaky pile of rocks that serve as steps.  It take a bit of nerve to take that first step down.

Here's another shot of the area off of Panoramio taken from the top of the falls during leaf-on.  The "walk-down" is nearly in the dead center of the photo.
