the mountains and hills will burst into song before you.

I'm not sure if I have words for how majestic the Wli Waterfall was.  It may just be something you have to experience.  If you go (and you really, really should go), you should be prepared to walk into the water.  I wasn't prepared, but I went in anyway.  I couldn't really resist.  The power of the water falling from the mountainside sent misty wind right into my skin as the waves met my ankles, then my knees, and my hips.  I just stood there soaked and in complete awe.  Really, I'm not sure how anyone could deny a Creator while standing where I stood.
