Youtube videos: Journey behind the Niagara Falls

The sound is like thunder, the sight awe-inspiring! Take a journey deep below and behind the heart of Niagara and stand in the mist where the mighty Horseshoe Falls tumbles from 13 storeys above! At Journey Behind the Falls, you'll experience the awesome spectacle of one-fifth of the world's fresh water crashing down to the basin below. During summer daylight hours, over 2,800 cubic meters of water thunders over the brink every second, travelling 65 kilometers per hour!
