You can drive right up to this viewing spot .There are warning signs about going past the fence, so I don't think you can hike down to the falls, at least not officially. Judging by the memorial on the fence (last pic) I don't think I'd want to ignore the signs.
Here's Jody at the lookout:
And here are some of the necklaces that are hung on the fence in memory of someone who died there. We wish we knew the story.
