Why do people visit Niagara Falls?

Because waterfalls are cool. It's a very romantic and pretty place to go.

I was there as a tourist just to see it since there aren't many waterfalls like that around and we also got it see the lightshow at night playing over the falls in different colors. it was very beautiful. Some people go there to be in the tiny boats and get close to it that way and others go there to get married.
