Niagra Falls is very big, but it's not he biggest at anything. It does have the most visitors every year. It's on the Canadian and US border. One fun fact is that the first person to go over the falls in a barrel was a 63-year-old schoolteacher. She sent her cat over first to make sure the barrel wouldn't break. After the teacher got out of the barrel, she recommended no one else ever do that again. Other people have tried, but now it is illegal, both in Canada and in the US.
