This is a must see place! Awesome amounts of water, the whole area is kept in a tidy fashion for the hordes of tourists. We went on a particularly hot day so the spray dried after a few seconds and was actually quite pleasant. The Maid of the Mist boat trip was good, takes you right beneath the falls. In the summer the flow of water is reduced as a nearby HEP station takes about 30% of the water away but it's still pretty good. Also nearby is a theme park with the claim of the worlds largest steel rollercoaster.
