I hope the viewing of water and waves would cool you down on this feels-like-40°C day in Toronto.
White Water Walk at Niagara Falls is one of the attractions of Niagara Parks, where you get to experience the power of the Niagara River’s Class 6 white-water rapids. Before I pay for the $12.50+tax admission, I think it’s a bit overpriced to get in to walk the 400 meters boardwalk trail. After the visit, however, I think it’s worth it! How amazing when Toronto is so close to this world wonder, which we as Torontorians can easily drive 2 hours to have this powerful experience! People usually stayed in there for 20-30 minutes and I stayed there for more than an hour to listen to the thunder of the river and look at the interesting clash of the waves. And of course, took lots of picture! As describe on their website, the sound really provides a deceptive calmness that relax your mind.
This is a place you must be there to experience, which no pictures or videos can replace your presence.
