But there's something special about this place. It has a noise! And the noise is very very LOUD! Click the video to see how loud it is!

If there's no sound, right click and watch on YouTube.

I obviously regret that the camera may not capture the loudness as our ears do..

So what's that loud sound? Obviously, water! What's that noise? You guessed it - a waterfall.
