Watch this 3 hour long relaxing video of a large waterfall. Some play this video to relax or for insomnia to help them sleep. Nature sounds like this river, waterfall, ocean waves, rain, thunder, and lightning help lullaby you into deep relaxation. A waterfall produces a calming noise similar to white noise. White noise also masks ear ringing (aka tinnitus ).

Filmed at the upper McKenzie River; Willamette National Forest, Cascade Mountains Oregon in 2010 using a Canon HV30 camcorder and Zoom H1 stereo microphone.
